From the vendor

Clone of the Phase 45 with some extra tweaks and features. Though a lot less in-your-face than the 4-stage Phase 90, this is far from a weak effect. Pleasant swirls abound. You won't get full-on psychedelic madness but there's plenty of swooshy phase going on. The board has a few extras over the standard one-knob pedal (though sweet and simple is the favoured configuration at FuzzDog HQ), drawn up by JC Maillet back in 2003: • Optional Mix control to vary the sound between phase and a kind of pitch-shifting vibrato • Pseudo Univibe mode switch. No, it isn't a univibe but it has a similar.... vibe! • Optional external pot for the bias control, rather than an internal trimmer. Why? well, you may want to tweak it slightly when selecting between Phase and Vibe modes. Up to you. However, we'd suggest keeping it simple so we're no longer offering Mix and Bias as part of the kit. Once you find the bias sweet spot you'll likely keep it there. Same with the mix. The vibe switch is well worth adding though. Kit can be supplied with or without the matched pair of FETs - note: you need these for the circuit to work, so if you don't have your own already you should include these. The kit is supplied with a vertical-mount pot which have round shafts, so you'll need set-screw fitting knobs. The Univibe mode switch is also board mounted. 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 partial kits, and will not take a battery. Knobs are not included.
