Here for sale 2020s OKKO Diablo GH Gregor Hilden Sig. Boost/OD/Dist. Gregor Hilden, top blues guitar player, collector and dealer of finest vintage guitars and amps – this man knows TONE. More than 10 years ago he bought one of the first Diablo pedals in a little shop in Germany and kept the Diablo as THE overdrive ever since that day, playing it in hundreds of shows and the numerous guitar demo videos in his Youtube channel. The Diablo GH offers exceptional dynamic qualities and super-clear, warm tone in a precisely adjustable 2-in-1 Overdrive and Boost pedal. Unlike many other overdrives it 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, the way how it reacts to your playing. It's in very good condition and comes as pictured.
