May Queen

RunOffGroove's sweetly simple one-knob emulation of Brian May's signature tone.

Smooth oomph and sustain for days without a wall of AC30s behind you. Very simple to tweak into life by ear if you don't have a meter.

Available with through-hole or SMT FET, depending on how confident you are with tiny, fiddly components. It's not that hard, honestly.

Here's the original project page if you fancy a read.

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.
