From the vendor
The classic +26dB boost gets embellished with active Bass and Treble EQ.
Not much more to say really. Loud boost with low noise floor and highly tweakable tone.
The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.
If you want the PCB without parts there's a link for that at the bottom of the page.
Partial kit: PCB, all board-mounted components), pots.
Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.
Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.
Builds are only available with full kits including enclosure. Please choose appropriate knobs.
Inspired by: Micro Amp +
Difficulty: Medium
PCB size: 50 x 33mm
