Be sure to add me to your favorites list Rocktek CHR-01 Chorus Guitar Effects Pedal, Beautiful Analog Sound with BBD Circuit, Modified with New Davies Type 1900 Clone Knobs. This is a Rocktek CHR-01 Analog Chorus Effect Pedal for use with electric, bass, and other type guitars. This one is in very good cosmetic condition and excellent performing condition. This is just for the pedal itself as shown, no power supply or any other cables included. This pedal can be considered a cousin to the Arion chorus pedal, as the same folks who made those also produced Rocktek pedals for a time. This pedal has standard 1/4" input and output, adapter input, 3 Dials that control Tone, Depth, and Speed. The original knobs have been replaced with some very nice (and easier to control) Davies type 1900 clone knobs. There is the footswitch in the front and a pop off battery cover that shows the battery compartment for a 9 volt battery at the top / rear of the pedal. This pedal is very clean and can do a variety of chorus sounds, from subtle to glimmering to bizarre rotary type effects. One thing that sets this pedal apart from many others is that the speed dial leads to a faster rate than your average pedal. Be sure that when you use it, use a 9 volt power supply for use with effect pedals, that has a Negative center polarity, as such ... Thank you for looking! Check out my Store!
