JDR3

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, 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). The '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. There's also a toggle switchable high frequency shelf filter to add extra 'bite' when needed.

Features:
• 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

As expected from a high end pedal. I give diamond credits for this one. I switched over from using a pod hd500 to analog pedals and I came across the j-drive. Warmer sounding than the Gt-500. I'm very happy with the tone quality and the boost together with the bright is a great feature.

I've had this pedal for 2 years now. I play a Strat and an SG through a Fender Hot Rod Deluxe. The pedal adds rich, smooth sustain and drive to a clean signal. Playing it through the drive channel on the HR Deluxe doesn't do anything. With my strat I can get a clean boost AND over drive at the same time (so if I don't have enough bump on my drive channel I can hit the clean boost and it will help). With my SG hitting the clean boost when already in drive doesn't do anything. I'm not sure why. The pedal does what a great overdrive pedal should do - give you many options from gritty to creamy sustain and letting the character of the guitar and amp still shine through.
