1393.1 | | SQUID::GOODWIN | I've got a mind to give up livin' | Fri Jul 21 1989 14:32 | 15 |
| I tried out a Champ 12 when they were first introduced to the market.
The one I tried didn't have the problems you mentioned, but I was
unimpressed with the overall performance/sound of the amp. I felt
it fell short of previous Champ models (Champ II to be precise).
I opted to purchase a Marshall model 5205 instead, which offered
similar features, but sounded much better, IMO. The 5205 is a
12 watt, solid state combo amp with 1 ten inch celestion speaker.
Controls are volume, gain, treble, middle, bass and reverb.
You might want to check one out before you make your final decision.
Good luck,
Steve

1393.2 | bad amp or bad tubes ? | ANT::JACQUES | | Mon Jul 24 1989 02:16 | 7 |
| It could be the amps are fine, but the tubes are bad. Good
tubes are getting hard to come by these days.
My Fender "The Twin" had tube problems from day one, until I
replaced most of them.

| I'm now on my third one and this appears to be OK.
Having tried this third Champ 12 I now realize the other two had
another fault. Namely, the GAIN control was acting exactly like
a VOLUME control. On this third box, the GAIN control dictates the
level of distortion and its associated volume control adjusts volume
as you'd expect.
Now for a real interesting fact. Both the first two I had (the faulty
ones) were Made in Mexico, this last one is Made in USA!

Damn!!! I just bought one last week and it is labeld "made in Mexico".
I haven't really played it yet at home but it sounded nice in the
store. The GAIN works correctly !!!

1393.5 | | WELMTS::GREENB | What a palaver | Thu Jul 27 1989 05:03 | 12 |
| I've also got one of theses beasts at home, and it works great.
It even makes my battered old Shaftesbury sound good! I have a
question, though.
I use a concoction of tape decks and a mini-mixer as a kind of
low-budget Portastudio (sound quality is fine for three or four
generations, but you have to get the mix right as it goes down).
Is there any way of D-I-ing the amp directly to the mixer, possibly
cutting out the speaker, so that I can blow my ears off without
blowing my neighbours doors off?

1393.6 | | AQUA::ROST | It's the beat, the beat, the beat | Thu Jul 27 1989 10:26 | 6 |

Not owning one, this is pure guess...
Use the line out if it has one, and plug something into the headphone
jack to kill the speaker. If no line out, try the headphone out
itself.

1393.7 | | LARVAE::BRIGGS | They use computers don't they? | Thu Aug 03 1989 09:08 | 10 |
| If you're referring to the feedback fault in .0 plugging headphones
on made no difference.
At a guess I'd say that there was some mechanical vibration in the
amp (mains hum on transformer?) causing the spring on the reverb
to vibrate and thus the feedback was being induced mechanically
in the power amp (as opposed to pre-amp) stage.
Richard
|
1393.8 | Yup | SMURF::BENNETT | Flicker Flicker Flam, POW! | Tue Mar 13 1990 17:58 | 8 |
|
I bought one too. Made in Mexico. Came with a severly Third Rate
6L6 installed. I'm sending the tube back to Brea with a love letter.
Class A on a budget. Sounds real nice. Too bad they used such
a cheap reverb and mounted it in the chassis.
Other recent buyers?

1393.9 | 6 months on | LARVAE::BRIGGS | They use computers don't they? | Wed Apr 04 1990 04:44 | 12 |
| Thought I'd add the last 6 months experience since I wrote the base
note.
No problems now for 6 months. Only criticism of the amp is the reverb.
Its got this sort of ringing to it above 1/3 reverb which is really
annoying. Will replacing any of the valves cure this? If so, anyone
know which one?
Failing this, I shall probably invest in some sort of echo/reverb/delay
box (I'll probbaly do this anyway).
Richard
|
1393.11 | No Hope.... | SMURF::BENNETT | | Wed Apr 04 1990 14:01 | 13 |
|
The ringing is caused by the nature of the beast. The reverb is
a cheezy (one spring?) unit mounted directly to the electronics
chassis. The only hope here is to use an outboard reverb or replace
the inboard one.
As soon as the year waranty is up I'm ripping the reverb out and
mounting RCA jacks in the back of the chassis and getting an
accutronics 3 spring reverb. At that time I'll probably also mount
jacks for the footswitch and the speaker.

1393.12 | Another happy Champ 12 owner | VINO::OCONNOR | Passion & Warfare | Thu Aug 30 1990 09:33 | 12 |
| Hi,
I just got a used Champ 12 for my birthday. I don't have a great deal
of experience with tube amps. My main amp for years was a Peavey
Pacer. I like the sound quality of the champ a lot. I live in an
apartment and I need a small amp that can sing. All of the other
small 'pratice' amps I looked at had grundgy sound when turned up and
the lead channels were, forget it. The Champ has a nice singing
quality to it. One question, where can you get nuts and washers for
Fender jack-plates channel 1 is missing them?

Joe, wouldn't it be nice if one could buy a bag of 10? I've never
found � inch phone jack harware sold separately, except at
Stewart-MacDonald where they sell them 100 at a time... I'm pretty
sure Radio Shack doesn't, cos I've looked there personally. Whenever
I find a junk radio or stereo, I always remove the � inch hardware a
stick it in my junk drawer. If you can't find what you're looking for,
I'll share (or maybe we'll both find a place to buy small amounts of
washers and nuts)
Regards,
Steve

1393.14 | Worth a shot | SMURF::LAMBERT | Just 'do it'? - *Here*?? | Thu Aug 30 1990 15:22 | 9 |
| Hmm.. Radio Snack *used* to carry that stuff. I know, I used to work
there. (Can't believe I admitted that in public. Well, I was young and
foolish at the time, and it was only for about a year... :-))
They used to carry them in the little plastic bags of stuff like crimp
connectors and wire nuts. They _have_ changed their stock considerably
in the last 10 years, so I could be all wet.

| Not to go down a rathole here, but I unscrewed the mounting nuts from
my Pacer and they wouldn't fix. It seems the Fender jacks are fatter
or the Peavey jacks are skinnier. Oh well, I'm going to rob my old
Sears amp, yeah I've even gut one of those, and see if that helps.
Other than this small problem. I love the amp. The best thing is the
nice low volume sound. I can practice without headphones fairly late.

1393.16 | HUM ON MY CHAMP 12 | GVA05::BERGMANS | | Thu Dec 05 1991 09:50 | 15 |
| I just bought a Champ 12.
I like the sound, but.............. I did not realize in the shop that
it has a hum....
As soon as it is heated up, about 20 seconds, there is a very noticable
hum, even with all volumes and gains turned down.
As soon as I start playing, I do not hear it, but it is anoying in a
quite environment.
Is this a bug or is this a feature?
Regards
|
1393.17 | | PHAROS::SAKELARIS | | Thu Dec 05 1991 10:16 | 16 |
| re .16
Most definitely a feature! Sure, you wanna know that the amp is working
without having to look at the pilot light all the time don't you. Yeah,
see that's that pilot *tone*. Now while I'm at it, I should let you
know that I got this used car for sale...its loaded with
*features*...driven only by my grandmother....
Seriously, the amp isn't likely to be the cause of that problem. Could
be a noisy ac line (dimmer switches), you maight have a Radio Shack
guitar cord or equivalent, or you axe might not be adequately
sheilded. If you get the hum without the guitar and cord plugged in
then you know its either the line or the amp. If you plug the amp into
a different ac source and its quiet, you know its the line.

1393.18 | | WEDOIT::KELLYJ | Master of rhythm, Phd in swing | Thu Dec 05 1991 10:27 | 8 |
| Do you get the hum with no instrument plugged in? If so, then I would
guess that there's a problem with the amp. Are you located near
another player with a similar amp, so you can A-B the amps?
My Fender Princeton Reverb is very quiet; my Deluxe Reverb is a tad
noisier, but still not objectionable.
|
1393.19 | Noisey tubes?? | GANTRY::ALLBERY | Jim | Thu Dec 05 1991 17:39 | 6 |

Even the it's a new amp, it could be the tubes. When I retubed my
Deluxe Reverb, it got a lot quieter.

|
1393.20 | HUM | GVA05::BERGMANS | | Fri Dec 06 1991 11:00 | 10 |
| Thanks for all the feedback so far.
What I do not understand is that the hum is there, without anything
plugged into the the amp and all volumes closed.
Could that still be the tubes? I was more leaning towards a faulty
diode or capacitor that would somehow let the 50 HZ (yes 50, I live
in Europe) through.

1393.21 | | RICKS::CALCAGNI | Don't fret! | Fri Dec 06 1991 11:17 | 5 |
| I've seen hum and other noise problems with all the volumes closed,
and the cause has usually been bad output tubes. Closing the volume
controls keeps any signal from going through the amp, but if the
noise is coming from inside the tubes themselves, it makes sense
that volume controls would have no effect.

HI, back again. 2.5 years of Champ usage now with no trouble
whatsoever. Ended up buying an Allesis Microverb III a year ago to
overcome the poor reverb. The hum has always been on mine but surely
this is the down side of a valve (sorry tube for you US types) amp? In
the old days all valve hifi stuff hummed. I have even got CD remasters
of 50s and 60s stuff where you can actually hear mains hum in the
quiter parts. This was presumably masked by rumble etc on LPs and 45s.
I have a number of questions about the Champ still though...
1) Why does the overdrive and reverb control affect BOTH channels? Why
would anyone want overdrive on BOTH channels at once? This is really
annoying because if you are using the 2nd input for rhythm then the lead
can't use overdrive. Seems really stupid to me.
2) WHY hasn't the tape input got an adjustable level control? Seems the
only way you can control the level of a tape input is from the tape
itself. Really stupid in my view.

1 - the two inputs are not independent channels. You pay big bucks
to get that.
2 - why charge the customer for the expense of a volume control
when most tape decks have them already?

I guess the problem is I have only come into electric guitars (as
opposed to acoustic)in the last three years. I would expect to be able
to take my tape output from the normal output you'd use for
hifi/recording and thus capitalise on the better quality sound than
from a speaker output.
In short my experience of amps, keyboards and other electronic musical
kit is very negative. It appears my expectations have been clouded by
the facilities etc that hifi systems offer.I guess what I'm saying is
that the whole area of amplified music seems, at times, to be a
rip-off.

Amplified music a ripoff? Compared to what? Are you talking real high
fidelity gear, or are you talk Sears hifi? Spend some time in the
AUDIO conference, and then come back here and tell us about exotic
cables that cost more than most peoples' components...
|
1393.26 | I've heard this before... | GOES11::G_HOUSE | Tommy The Cat | Wed Dec 11 1991 12:43 | 44 |
| This reminds me of a conversation I had once with a non-musician
friend.
I was showing off my brand-y new Marshall JCM900 amp head, had it
sitting there on the "Hi-gain" channel with the gain cranked...
He: "What's that hissing sound? Is something wrong with it?"
Me: "No, they all do that"
He: "What? Do they use cheap components in 'em or something? You'd
think for 700 dollars they could make something that sounds clean."
Me: "...I suppose, but it wouldn't sound right clean."
He: "I can go to any store and pick up virtually any stereo for
$100 and it won't hiss like that!"
Me: "That's because it doesn't have a high gain tube preamp sitting in
front of it!"
He: "TUBES?? O-my-gawwwwd! Why don't they use up to date solid state
technology??? No *wonder* it doesn't work well!"
Me: "Some companies do, but I don't think solid state guitar amps don't
sound good"
He: "They have to sound better then that"
Me: "You're missing the point, they don't distort right"
He: "DISTORTION???? It DISTORTS your signal???"
...the conversation went downhill from there.
Bottom line was that he couldn't be convinced that an amp should not be
absolutely crystal clean and couldn't seem to understand why anyone
would want to distort their guitar signal. (and this was not someone
into classical music or other some other type where clean guitars
prevail, he just couldn't comprehend where that sound came from) He
thought I'd been robbed to pay that much for an amp that made a hissing
sound when you turned it up.
The real problem (to me) is that you can't get a natural sound from a
perfectly clean electric guitar signal, it doesn't sound right. Some
people think they want a perfectly clean sound to sound like an
acoustic guitar, but I don't think it sounds acoustic. The signal you
get from an electric pickup is different then what comes off a real
acoustic instrument and needs to have something happen to it before it
sounds very natural.
JMO, naturally.

| What makes me laugh is that his $100 stereo "colors" the signal too.
If you want pure amplification and signal integrity, you have to spend
$thousands$ that would be equivalent to studio/PA gear.
He's confusing his applications of amps. The real amps that he would
want are made by Crown, Boulder, Bryston, etc. These amps typcially do
not color the sound and are very pure signal wise. That's why studios
use these brands most.

1393.34 | Low Noise Isn't Impossible, Just Expensive | RGB::ROST | Felix Pappalardi in a previous life | Wed Dec 11 1991 16:51 | 20 |
| High gain and tubes don't equal hiss automaticaly. There's plenty of
super high end tube hi-fi gear out there and hiss aint part of the
equation. The preamplification of a magnetic or moving coil cartridge
is a pretty high-gain application. The whole situation of noise in
guitar amplification is a sore point with me, too. First you crank the
f**k out of the gain then you run through various signal processors
which tend to *increase* the hiss levels than into a noise gate to
clean it up and an aural eciter to restore the lost high
end...?????!!!!!?????
On the other hand if guitars came with *low impedance pickups* and
were designed for lower noise overall (heck, most guitars off the rack
aren't even shielded!!!) then all that noise would go away.
When I turn my bass amp on full blast with no input, is quiet as a
mouse. I have to stick my ear up against the grille to hear the hiss
to see if it's on. 99% of the hiss I hear when playing is actually
coming from the *instrument*.

Well, back again. 3.5 years and zero problems with my Champ 12. Only
problem is I can't understand why I bought it or why anyone would buy
it in the first place! Let me explain....
I've recently started to do some gigs in small halls in a group and the
Champ 12 is plainly inadequate with regard power. I'm currently using a
Peavey 80 watt amp for these events. Now this Peavey sells for
*significantly* less than my Fender Champ 12 here in the UK.
Now having said this, the sound of the Champ is superb. The Peavey
cannot touch it for tone and the Champ's overdrive is lovely and warm
(if a bit unpredictable), much better than my Boss ME-6 can generate
through the Peavey. So, the conclusion I've come to is that the Champ
is a superb quality low power amp. But why would anyone pay all that
money for something so low powered. On the face of it, its nothing more
than a practice amp. Talking to a guy in a music shop about part
exchanging the Champ for something more powerful he was saying "no
problem, I can't sell enough of them".
Or, is its real niche being miked up to a suitable PA? Is that the real
attraction of this amp?

| RICHARD,
You're right about the tonality.... I use a Special 130 Peavey and I
have found serious problems "warming" my sounds through it, but connect
in a 4x12 or a 4x10 to the spare speaker socket and it screams... it is
a bit of a metal type combination but I find it works equally well for
the rock/pop stuff I am doing with the band I play with...
Why not invest in something like a Valve State Marshall...
