From the vendor
Another Dumble-in-a-box pedal... but this one tops the FDHQ chart for those tonal needs. Let's get all the usual cliches out there - organic, touch-sensitive, tube-like. They all fit. There's a little whiff of magic dust in this one. We've never played a Dumble amp, but you really will think you're plugged straight into something warm and willing rather than a little box of bits. 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, 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 enclosures. Please choose appropriate knobs. Inspired by: Simble Difficulty: Medium PCB size: 50 x 30mm Knobs required: 4 Enclosure: 1590B Direct-Connect compatible (4-way) Download theINSTRUCTION PDF
