More than 10 years ago, Gregor Hilden, a top blues guitar player, collector and dealer of finest vintage guitars and amps bought one of the first OKKO Diablo pedals in a little shop in Germany. Guitar aficionados have no doubt seen Gregor's YouTube videos (and teddybear mic holder!), where he has used the Diablo as his main overdrive pedal leading scores of players to wonder, what is that awesome sounding overdrive he's using? OKKO has honored Gregor with his own signature Diablo, which we have here. 

The Diablo GH offers exceptional dynamic qualities and super-clear, warm tone in a precisely adjustable 2-in-1 Overdrive and Boost pedal, that unlike many other overdrives, works perfectly with clean amps. The GH model is based on the classic Diablo but comes with a few tweaks and a set of new controls that affect the "feel" of the pedal.

Condition: Like new w/box. 


  • DYN(AMIC) adjusts the internal voltage from about 6 to 18 volts. 
    Increasing the headroom results in less compression, tighter bass and more punch.
  • FEED controls low frequencies in the input signal allowing tight and transparent sounds even with the fattest sounding neck pickups. 
  • BODY control is a bit different from the regular Diablo, adds low mids in the first gain stage for thick, singing lead sounds.
  • INPUT 3-position-miniswitch sets the sensitivity of the input gain stage for best interaction with your guitars. Just try and find your favorite setting.
  • MIDS changes frequencies in the tone control. Perfect for matching pedal and amp tone.
  • The BOOST section is a completely independent circuit and is located AFTER the DRIVE.
  • BOOST knob is the master volume (gain is set fixed), TONE controls treble content of the boosted signal. Dial back for sweet boosted lead sounds.
