Mini Booster

Tremendous little booster that can do mega dB of clean or add grit if you want it.

Jack Orman's (AMZ) μ-amp design has been a DIY staple for years, and it's almost unforgivable it's taken us this long to get it in store.

Tweak it a little to create your own version of the highly sought after Bad Bob Boost.

Available with through-hole or SMT FETs, so save yourself a couple of quid if you're handy at the fiddly little stuff.

The kit is supplied with a vertical-mount pot which has a round shaft, so you'll need a set-screw fitting knob.

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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knob is not included.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
