Quotewhat effect do the caps C4 and C6 have on the circuit?i have tons of volume. as in unity volume is about a quarter of a turn, and C4 is the only sub i made.although it does overdrive the crap out of my amp...

Quote from: merlinb on February 12, 2011, 08:04:06 AMHere's a very dirty sound clip. LP into a home made 18watt and 4x8 cab, SM58 into sound card. Practice volume. No processing.First is the bypassed sound, then with gain pots at about 3/10. Then with both gains close to max.Then I switch two of them in series at max gain (but unity volume), just for fun!www.freewebs.com/valvewizard2/SparlGapMixdown.mp3(If it tries to redirect you back to this page, just cut and paste the URL into the browser instead)
Quote from: misterg on February 09, 2011, 07:05:10 PMwhat did you sub C4 with?Quote100pf.i used log pots throughout. unity gain on mine is about 9 oclock. i guess the tolerance difference could account for some of this... either way it sounds good.i guess it dosnt really matter to me too much because i can always turn it up
