3207.0. "Acoustic Bass Guitar Amplifier?" by IRNBRU::NIVEN () Thu Jun 20 1996 05:21

Hi,

I have an Ovation acoustic bass guitar that I bought last year while on business
in Korea. I love it. I've been using it mostly acoustic but sometimes through my 
Peavey KB100 (3 i/p keyboard combo). I'm now going to be emigrating to 
California so I sold the Peavey (wrong voltage!). As a result I was messing
around and tried the Ovation through my HiFi and I have to say I liked the sound
(at least at "home" levels). It was clean and full.

Does anybody have any recomendations for an amplifier, suitable for an acoustic
bass, that I should look out for when I get to California? How much should it 
cost?

Cheers,
       John

Laney, and Peavey are making Acoustic guitar amps.

I'm not so sure they make bass amps though.....

    My preference for acoustic bass is Polytone.  I use a Polytone
    Minibrute (w 1 12" and 1 mid-range tweeter) which produces a soft
    tone quality that lends itself to acoustic playing.  I use this 
    primarily for jazz playing on an upright bass.  Of course, that's a 
    matter of personal taste and really depends on what YOU like.  For 
    electric bass, I use a Peavey Mark III which, since has been vastly 
    improved by more choices from the Peavey line.  However, for my needs, 
    the Mark III is adequate.  It has a wide adjustment range of pre & post 
    gain eq to yield a wide range of bass sounds.

The Polytone Minibrute (sounds like my wife %^}) sounds interesting. I assume
that with a 12" its probably physically small, which is good. I've not heard of 
Polytone before in the UK. Does it have anything to help minimise feedback? I've 
not had a big problem with this 'cos I usually just play with myself in my 
bedroom %^} , but it did seem that it would be a problem at higher volumes.

3207.4Carvin may be an optionCUSTOM::ALLBERYJimThu Jun 20 1996 13:012
    Carvin claims their acoustic guitar amp is also good for acoustic
    bass guitars.  It's a two way design (12" woofer + a tweeter).

I'm *very* curious about this amp.  I play double bass in a bluegrass band
and electric bass in another band that I don't know how to describe, and
I'm wondering if this amp might work for both situations.

    The Gallien Kruger MB200 seems to be very popular with jazz upright
    bass players in the Boston area; it may even have replaced the Polytone
    mini-brute as the "industry standard" for this application.  It's solid
    state, 1x12, 100 watts (I think) and still the undisputed champ for
    portability in it's class.  MB200 is old technology, and I've had my
    concerns about GK in the past, but everyone I've spoken to seems to
    think these are very reliable.  Got mine for $300, used, which is
    typical.  There are updated versions of this amp that don't seem to be
    as popular with working bassists; not sure why.
    
    Of course, the base note asks about amplifying an acoustic bass guitar.
    This is a relatively new field and I don't think any consensus has
    emerged among players as to what works best here.  The solutions that
    work well for upright may not necessarily do the job for ABGs.

   Carvin also makes (or made, I haven't seen a catalog in a while) the
   PB150 - a 150w bass amp with 1 10" speaker, noise gate, and compressor.
   It's about $250 US, new.  I've got one and love it, though I use a
   regular electric bass with it.  Believe it or not, even the 10" puts
   out plenty of low end for most (reasonable :-) situations.

They still make it, but it's $299.  If I was just playing the electric
bass gig I'd probably get one.   The AG100 intrigued me 'cause one of
the channels has an XLR mic input.  I figured I could use that to combine
a mic with a pickup for the double bass.  On the other hand, the AG100
costs $150 more.  Maybe I should just get the PB150 and a Fishman Blender.

    One other advantage to the Carvin "acoustic" amp is that the tweeter
    can be turned off for bass applications if so desired.

3207.10Have they got the guts?IRNBRU::NIVENTue Jun 25 1996 05:5229
Thanks for the info so far....!

A couple of people have suggested using the acoustic guitar amps. My experience
of electric guitar amps is that they have open backs and "colorfull" sounds!
The speakers in them being choosen for their "sound" not their reproduction.
The open backs limit the low frequency response of the cabinets. I have no
problem with this as IMO you have to regard the combination of the electric
guitar (or bass) *and* the amp as "the instrument". 

However, in my case, running through the HiFi started me thinking more in terms 
of reproducing the *sound* of my Ovation Bass. I guess its the same as looking at 
it as a small PA.

Is the philosophy of acoustic guitar amps basically to provide a small PA?

What about the low frequency response? 

re: .8
The Peavey KB100 inputs, that I used to have, had switchable gain (you just 
pulled out your knob ;-}) and you could use it with a mic. All 3 inputs were
mixable. Being intended for keyboards, it had a 15" and a tweeter, in a ported
box. I used it with drum m/c, electric bass, electric guitar, mic, whatever...

Of course "Jack of all-trades, master of none" probably applied, hence I started
to wonder what a specialized amp may offer extra.

Does anybody know how much a KB100 (or equivalent) costs in the US?
