From the vendor
Neat amp-in-a-box bringing you mid-focused, touch sensitive Dumble style tones.
Based on the 80's blackface model, it's very tweakable thanks to the 'Dynamics' control and gain range selector switch. Keep it low-medium for sweet mild break-up, or flip it into high/fat mode for extra oomph.
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 and vertical-mount pots. Please choose appropriate knobs.
Inspired by: Dumble Blackface
