J-Drive Mk3

Now shipping! The Mk3 evolution of the J-Drive integrates even more functionality and tonal variations into the combined drive and clean boost concept.

In the clean boost section, the Mk3 has an independently switchable clean boost consisting of a Vishay JFET and BJT clean boost. 

Borrowing from the limited edition J-Drive TR, we've also added a cool transformer output stage to the overdrive section - it has a wonderful smoothing effect on the upper mids and highs, placing an inductive source impedance at the amps input as a guitar's pickup would (but at a lower output impedance so it works great into other pedals as well as amps). 

Our 'Close Asymmetry' overdrive circuit utilizes a Schottky barrier diode for smooth asymmetrical clipping - which combined with the transformer output gives a liquid smooth sustain with punch. The 'Warmth' control offers a unique tonal control adding low end gain while simultaneously cutting top end- perfect for warming up a bright amp or guitar. We've also added a toggle switchable high frequency shelf filter to add extra 'bite' when needed.

功能特色:

- true bypass signal path for both the clean boost 
and drive sections
- discrete clean boost circuit with JFET input/BJT
amplifier
- premium audio components, including 2% polypropylene capacitors, 1% metal film resistors and a Burr Brown OPA2134 opamp

- post-volume control overdrive transformer output stage 
that smooths upper mids and highs
- 'Close Asymmetry' Schottky diode clipping circuit
- switchable highpass shelf filter for additional 'bite', 
implemented without additional active components
- battery or standard negative tip 9V DC adapter operation

Oh my god!! This sweet baby is the best overdrive pedal out there in the market. It sounds even better than the Fulltone Fulldrive 2 MOSFET. It makes my solid state amp sound like a tube amp. It just warms up the signal significantly and you can get a wide range of sounds using this pedal and all of them are excellent!

The sound is just phenominal and it's the best Overdrive I've ever heard. I love especially the clean boost. It can be either by itself or with the Overdrive. Sounds so amazing. Though I would like to have another pedal with a heavyier distortion this pedal's tone stood out from all the rest and that is why I bought it

"Just got one of these and bottom line is, they rock! The drive channel is really smooth, very mild to no mid hump (close to flat with the bright switch on and warmth about halfway). The boost channel is even better! "
