experiment with. The MOSFET op amp cannot run at more than 9v. But the other
op amps can run at 18v.
·
Output buffer highlighted in blue. The buffers are where most of the mosfet noise
comes from.
·
Clipping section highlighted in red. Note that while you can use either the MOSFET
transistors as clipping devices or the LEDs as clipping devices regardless of what
specs you build the rest of the pedal to, you cannot have components on the PCB in
both of these spaces at the same time. It's one or the other in this case. If you
wanted both, you'd need to get rid of the stock silicon diode clippers and put the
LEDs in their place adn then leave the spaces for the LEDs on the PCB empty.
·
Boost Circuit highlighted in green. The standard silicon boost will sound fuller and
will be louder but cannot run at more than 9V. The MOSFET boost will not be as
loud as the silicon boost, but it will have some sparkle to it that many guitarist like
and it can run at 18V.
Making the Boost louder
- 1. You can squeeze more volume out of your boost by
adjusting the 470ohm resistor highlighted in red. This could be considered the gain
resistor of the boost circuit. By lowering the value of this resistor, the boost circuit will
