Verb Engine

Not for the easily offended, or those looking for nice, clean reverb. You have been warned!

This piece of work is less a reverb than an unpredictable, untameable texture machine.

Based around the ever-popular Belton 'brick', this circuit twists and tweaks the boundaries of this unit. Controls for reverb level and volume are pretty straight forward. Add the gain control to the mix and things get crazy. The extra signal being mixed with the verb causes all kinds of overloaded, distorted havoc which is both fun and satisfying. Two distinct tone modes are available, giving you dark, cavernous rumbles or bright, spangly twang. Something for everyone, as long as you're a fan of the unusual.

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.
