hi, i commented on another thread, but it doesn't seem to be showing up on the "what's new", so maybe nobody has seen the question. hope this is not an anoying redundancy if you've scrolled past this question already.
i've just tested my two sticks of derm board and the effect is quite nice, but there is a very high pitched squeal/howl type of noise accompanying the distortion. i have seen a suggestion to go for another NPN transistor in the middle slot, that has an hfe of around 200. i don't currently have a way to test that (on the way) but the handful of the 2n3904 units that i tried sounded exactly the same. is there a nearby component value that could be adjusted? is there another common NPN that i might try, or should i just try all of my 30 or so 3904s and hope one works out? thanks for any help!
