Diamond Guitar Pedals

The J-Drive is two independently switchable pedals in one:
a simple clean boost circuit along with the core Diamond Drive circuit.
Both can operated at the same time for a higher gain tone reminiscent
of the Lead + Drive setup of the stock Diamond Drive.

Compression setting: Be sure to try out the different compression settings by setting the switch as described
in the user manual. The JD offers a less compressed, more raw setting as well as more of a classic
overdrive sound with longer sustain. We've found the classic setting works best with Marshall master
volume amps like the JCM800.
