Earlier this week I picked up a J-Drive MkIII from Axe And You Shall Receive in Brantford, Ontario. The You Tube demo posted by ProGuitarShop.com gives a fairly helpful overview of what this pedal does. http://www.youtube.com/watch?v=h2q-SFEROjg It's an enjoyable departure from yer same old. The "warmth" control is especially interesting; it's a combination of tilt EQ and gain boost. The pedal is just a lot of fun to use, and the build is rock solid, all top quality and beautifully finished. :AOK Now I'm in big trouble, because Brantford is an easy drive from where I live. Gotta snag me a Diamond Compressor and a Memory Lane 2.
