Built it. Sounds good or maybe nice at low strings for chugging and lead stuff BUT it had that kind of OCTAVE UP going on at the higher frets(12th fret up) . I find it weird. Is it supposed to sound like that?. LOL

What did you use for Q1-Q6 and what opamps? (what hfe are your trannies? )
Plus, did you use a charge pump or straight to 18v?

I used the specified mosfets LND150N, 2N5457 fet, and an equivalent of 2N1306 germaniums(they look really identical with the said germanium tranny). Opamps were all NE5532. And lastly, I'm using an 18V adaptor.

It turns out I mistakenly installed a 47n cap instead of 4n7 in the mid freq filter :scratch: . Now it's working fine. BTW, Germanium transistors are WEP641.
