Valve - 12AU7 Warm Boost Pedal
VALVE is an all-tube boost pedal (no silicon involved) operating in starved-plate and starved-heater mode, which is difficult to pull off. Most attempts (Matsumi) have marginal performance due to excess grid current at such low bias. This new design solves those issues, breathing life into the tube, achieving full bandwidth and low-noise performance, all while maintaining that gooey non-linear tube goodness. This pedal will fatten up your tone like nothing else. Destined to be your always-on pedal. Works great on bass too!
- True bypass
- 10dB to 20dB gain (tube dependent)
- 12AU7 tube (included)
- Level control
- 100k ohm input impedance
- 25Hz to 12kHz bandwidth
- 9V @ 135mA power (up to 12V)
- "Tonight, I put a NOS Sylvania (mil-spec) 5963 into my Valve pre-amp pedal ... OMG! My 5w Marshall is loving it! This has been one of the best pedal purchases I’ve ever made."
- "Good stuff. I run it in front of a Valeton pedal and it really rounds out the clean tones which is the reason I bought it."
- "Love the 12AU7 boost. I've been using it in front of my quilter US superblock and it's a perfect fit for adding that extra something in terms of feel and warmth."
- "Best place I've found is at the end of my pedal chain, right before the amp. That's where it will live on my board, always on. Really gives the Quilter some fat. Nice work!"
- "This pedal is fantastic! I’ve been playing all afternoon. Noticeably boosts my Marshall C5 at low volume. I think it’s going to take the place of my Maxon OS-9, as it boosts equally, but sounds more organic."
- "Hello Jim, just wanted to let you know this pedal is awesome and is doing exactly what I hoped! I am using this with a vox minigo amp, and this pedal is taking it from slightly annoying tone to really good tone. I am delighted. Took me a while to figure out the right settings but once I found it I am very happy :-) Thank you for making this pedal."
- "I played the valve boost through both my bass and guitar. On bass, I can definitely hear the sound liven up with the additional harmonics. It also adds more of a growl than a drive, which is good thing for most bass styles. I do appreciate the lower fundamental not being cut off like most pedals do. For guitar, this thing is a game changer. I'm playing into a tube amp and this pedal increases the dynamics even that much more. It sings. It's become a part of the instrument as a whole. A keeper for both instruments for sure."
- "I'm convinced that your starved voltage circuit works well, and sounds great. I'm only using it (so far) set at 9:00 (so not really distorting much) but it adds a nice crunch to the 12AX7s. The tube boost sounds great going in to my amp sims in the computer."
