Rather super circuit utilising the blend functionality of the Maestro BrassMaster, put together by Moosapotamus.
A somewhat bigger build than your average blend circuit, but well worth the effort. A phase switch means you can flip the signal being sent to the effects loop to alleviate any phase cancellation issues, and a Big Muff tone control on the loop give you a world of possibilities.
With pots for Send Level, Return Level, Tone and Thru Level you have complete control over every stage. There's also a Tone Bypass switch for you signal purists.
Available in three different enclosure configurations. Those with top-mounted jacks have the controls set further down the face.
Works equally well on guitar or bass.
Pots and switches are board mounted (round shafts), but you can wire up 'normal' splined shaft pots if you prefer.
Pot spacing is 22mm - take that into account when choosing knobs.
Kit includes: PCB, all components, hook-up wire, 3PDT footswitch for true bypass, high quality jack sockets, DC socket, battery snap, LED. Enclosure (pre-drilled) is optional and will not take a battery. Does not include knobs.
PCB size: 84 x 32mm
Knobs required: 4
Direct-Connect compatible (4 or 6 way)
If you want the kit pre-build you MUST include the enclosure and choose the board-mounted pots option. Don't forget your knobs!
