Accutronics BTDR-3H Reverb Belton Brick
Clever reverb module used in lots of boutique pedals and DIY circuits. No, we don't currently do any kits that require this brick, but there are plenty out there.
These are the horizontal mount version, with pins at 90° to the body.
This brick has a variable decay time, so only comes in one flavour.
Size: 38 x 32 x 12mm
