From the vendor

A pedal incarnation of the gloriously obnoxious IVP rackmount preamp.

Wuh? You think the Harmonic Percolator was the secret to Steve Albini's in-your-face guitar assault? No - it was the Instrument Voicing Preamp. The HP was the icing on the cake, so yeah - grab yourself one and play them together.

Clangy, crass and quite unique. You've played nothing like this. Active EQ comes BEFORE the distortion section, which makes it feel... just different. It's easier to tune it to the frequency boost you're after.

This isn't the full preamp by any means. It is a perfect distillation of the raw essence in a much handier package.

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: IVP Preamp / Surveyor
