3229.0. "Popping problem with Fender Amp at shutoff" by EPS::DEANE () Tue Sep 03 1996 13:42

Maybe this has already been discussed in this conference. If so,
point me at the right note...


I have a Fender Pro 185 Solid State Guitar Amp. It makes a LARGE
popping sound whenever I turn it off. If the amp volume was set high
it would probably blow the speakers. I called Wurlitzer and
Daddy's Junky Music. They said to call Fender. I called Fender and
they said "that's the way they work". The rep knew EXACTLY what
I was talking about from the get-go. He said to minimize it:

	1) turn off the reverb
	2) switch to the "clean" channel
	3) turn down the volume

I thought, gee, why don't I stand on my head and start singing a
song too before I power down!!!

So, since this is such a "common" problem, one of you machine-heads out
there must have solved this problem ala a soldering iron and some
minor electrical engineering. Anyone got a solution to this? Like caps
across the power switch? Or relays just before the speakers? Let me know.

Personally, I think the Fender amp is poorly designed to allow a transient
like this to occur at all...

   My Fender Performer 1000 (MOSfet power amp section) does the same thing.
   I've "adjusted" by teaching myself to unplug the guitar at the amp before I 
   shut down.  

   Just one of those things...
