hey Boris,
These amps do hit the power stage really hard. if you use the preamp out jack on the back of the amp, you can plug the preamp into a mixer to see what the preamp is doing. my guess is that it is clean. you can even record some signal coming out of that and post it here. might be helpful to determine if things are wonky.
I have seen resistors go way off value in the mid circuit, which has caused some unpleasant sounding distortion/muddiness. I wouldn't assume a 6k11 is bad.
now as to your feelings about the treble, mids.
This amp is not a fender. so when you put the treble, mid and bass at 12 o'clock, that should be a flat frequency response. from 20hz to 20khz. This is not always desirable for guitar and for someone used to fenders/marshalls this may feel like very unfamiliar territory, this is because flat frequency response on a fender/marshall isn't really possible.
so you need experiment the EQ to shape your tone. a few tips:
1. As I mentioned before the controls are flat at 12o'clock, so start with treble/mid bass all there, and think about what frequencies you want to remove, and try subtractive eq first. this is especially true with the mid eq (see #2)
2.The mid has a switch that selects the frequency band. 300hz, 1k or 3k. this mid control has options. I have never found boosting 1k to be pleasant but I did know people that liked this. you mentioned your kids were at 3.15... this is a considerable boost. and if your switch was set to 1k, I bet it was unpleasant.
3. turn the ultra-high off. the ultra high uses 120pf ceramic caps. I don't like the cap value or type, I switch it to 250pf 500V silver mica. These sound much less harsh and will tame the ultra-high considerably
4. please check out my EQ mod http://www.vintageampeg.com/ampeg-tone-s...n/#more-22 This can help a lot with the harsh sounding treble, and the fluffy lows. replace with tubular film capacitors and you will be much happier.
also, what kind of guitar are you using?
