Diamond J-Drive MK3 Overdrive with Clean Boost
Item: DMDJDRIVE
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.
