From the vendor

One for the fans of the 'different'. A wonderful combination of reverb and fuzz, but not just any combination. Throwing convention out of the window, this fella verbs things first, them fuzzes what comes out. The results are are as interesting and fun as it sounds. Lots of scope for all kinds of weird textures and drones with deft use of the controls on hand.

So, lots to play with here. Right up front you have a dry/wet mix pot. This was a trimmer in the original, and you can stick with that if you want, but why keep controls locked up in the box? It's unlikely you'll want much dry going on, as the fun all happens with the signal drenched in 'verb, but with the reverb bricks having a slight pre-delay you may want some to maintain some pick attack. You then get your reverb controlled by the dwell pot, along with your dialled-in amount of feedback. Turn that baby up and you're into self oscillation.

Then BAM! You're into the Fuzz-Face style fuzz section, followed by a tweaked Big Muff style tone section. Your dry/wet signals are combined just before the fuzz.

For extra possibilities you have a drone function. This pumps more gain into the reverb feedback section, keeping things going without any guitar. Very handy. The drone level was, again, an internal trimmer on the original but it is an essential external control. You have the option of having a momentary or latching footswitch for the drone function. Our suggestion - latching FTW.

Supplied with Lumberg jacks which are top-mounted.

NOTE: This kit does NOT include the Belton Brick. If you need one please order it on this page. The original uses the LONG variant, and for the most fun we'd say stick with that.

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 (not BTDR-2), 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 and vertical-mount pots. Please choose appropriate knobs.
