From the vendor
Lovely little drive designed to emulate the classic and impossible to find Vox 4 and 7 series amps. What are they? Only an integral part of the guitar tones on The Beatles' Revolver and Led Zeppelin's II. What's not to love? Small, simple build that can be tweaked to suit your guitar with a small turn of the FET biasing trimmer. A little hotter? No problem... Wide ranging gain control and a lovely tone sweep make this very versatile. 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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included. Builds are only available with full kits including enclosures. Please choose appropriate knobs.
