Diamond Pedals Cornerstone Overdrive

This pedal is near mint condition. No scratches or wear to be seen. It sounds great, the switch works perfectly, the jacks operate without any issues, and the knobs turn silently without any scratchiness. Save yourself some money and buy an essentially new pedal from us! Includes the original box, packing material, and manual.



The Cornerstone is the all new “variable personality” drive pedal from Diamond Pedals.  Utilizing multiple discrete gain stages with distributed dual Gain controls the Diamond Cornerstone is capable of anything from touch-sensitive low gain grit to searing leads.  The Diamond Cornerstone features two discrete Gain controls for an unbelievable amount of different drive profiles.  The active Mid boost/cut control allows you to dial in various shades of tonal bliss from British to American and the Treble Profile switch acts like a Bright switch on classic tube amplifiers for matching the pedal to your rig.  The Diamond Cornerstone is one of the most versatile drive pedals to hit the market in quite some time and will lend itself well to any style of music from classic to modern.

Diamond Cornerstone Features:

  • True Bypass
  • Dual, Discrete Gain Controls
