From the vendor
There's a doomy one-knob fuzz capable of atmospheric disturbance right here.
This one is based on that but goes stratospheric, prodding the void where the eldritch horrors lay in wait.
There's some dark magic in the combination of the MOSFET and germanium transistor that takes this one into unknown realms. Crank up that depth control and see new colours...
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: 3-knob Hybrid Cthulu
Difficulty: Easy
PCB size: 50 x 30mm
Knobs required: 3
Enclosure: 1590B
Direct Connect compatible (4 way)
If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability.
