Re: Fender Champ 12



Hi Ray,
 
Check the Champ12 thread in Guitar Tech forum down a ways,
I had a couple links to my screen voltage mod, it's easy and helps
the clean channel give a little more of what's needed, both channels
really since it's the power tube. Runs hotter but that's the way I like
it, supposed to be class A anyway.
 
I replaced the ceramic signal caps with mica or film and it helped
the preamp, before changing values if you are going to get a better
speaker (especially for overdrive) I would voice it to that.
 
Good luck with the overdrive channel, exactly there is the least
progressive gain I have ever seen, never clean enough or dirty
enough without being harsh, there is almost no more gain clockwise
than there is CCW, and articulate settings stay louder than the clean
channel. I put the OD gain at 9o'clock and OD volume at 3o'clock
and voiced that setting to be a little better, but still I prefer a clean
LPB2 pedal in front of the clean channel for workhorse overdrive.
Then I still can bypass the LPB2 and use the Champ12 OD
sometimes which is harsher, then kick in the LPB on top of that for
some really aggressive screaming. Still there's a volume boost each
step of the way, and it helps to turn down the reverb as you go. It'd
be interesting to find out what you do here, and with the reverb, its
a microphonic feedback special.
 
And have fun with those red knobs and removing nuts from every
pot before you can fix the board, don't get violent
