I have tried to make a vero layout for myself. The switches are spdt but shown as dpdt as mine are three columns wide.
It is unverified and I am myself experiencing some problems. I have build it also on breadboard and am having the same problems so I am not sure if I am overlooking something or if there might be some problem with the schematic (
members/soulsonic/schematic/LAL_SuperOscilloFuzz.GIF).
I get an extreme fuzz plus oscillation controllable with the adjust pot and guitar volume pot.
Switches 1,4, and 6 change the tone a bit and also the pitch of the oscillation. So this seams about right.
But switches 2,3,5 work only in one position. In the other I get either nothing or very low output fuzz with no oscillation.
Switch 3 works only when switched to the 10K resistor. I can make the other position work with a resistor as low as 1K5, but with lower values or with no resistor at all(as on schematic) it does not work.
Switch 2 works only when connected to the collector of Q3. Not when connected to the emitter.
Switch 5 works only when connected to the collector of Q2. Not when connected to the emitter.
I would really appreciate if a successful builder of this fuzz could give me any insight on these problems.
Would be also grateful for any comments on the Q2-Q3 section, I am having a hard time trying to understand how it is supposed to work. (especially the bias of Q3...)
Thanks a lot!
