evo ti 1 jednostavna igračka.
čak za bass treba pobacati neke komponente.
"Bass Guitar, Electric Piano
As shown, the preamp is just as usable for bass or electric piano as for rhythm or lead guitar. A couple of changes that you may consider are ...
Delete the clipping diodes (unless fuzz bass/piano is something you want, of course). If these are removed, then the output should be taken directly from the Master output pin (M-OUT in Figure 1), so leave out / change the following ...
Delete R14, and D1-D4
Delete Q1 and associated components (C14, C15, R15, R16, R17)
Delete VR5
Change R13 from 4.7k to 100 ohms
You may also want to experiment with the tone control caps - I shall leave it to the builder to decide what to change, until I have tested a few possibilities. C3 and C8 may be increased to 4.7uF to provide an extended bass response. If the gain is too high, simply increase R11 (10k would be a good starting point and will halve the gain)."
