I had my settings like this:
Preamp Gain - 7
Master Volume - 8
Treble - 6
Middle - 7
Bass - 5 (Sometimes

Presence - 5
The sound was really spiky, harsh, sounded like there was a load of hash in the distortion and the clean sound (guitar volume turned down) had a big mid hump that made strumming sound really bold and stand out.
Anyway at the end of the night (had to find out then didn't I!) I was messing about trying Solodallas settings for the Let There Be Rock tone and it sounded great. When experimenting I found that if I turned the Middle up past 5 the tone would get spikey and the bad tone would come out. Also with the master on 8 it seems the pre amp gain was best set at 6.
So what I'm getting at is how different the 2204/2203 tone controls work compared to the 1987/1959 amps. Anybody else find this? Maybe it's the JJ 6V6s?
I suspected that the primaries might be the wrong way round giving me positive feedback but the amp wouldn't clean up if that were the case.
