LIMITED EDITION CUSTOM AMP SHOW EDITION!This was limited edition made for the NY amp show. This is an Octavia Fuzz guitar effect pedal based on the Tycobrahe Octavia circuit. Originally designed by Roger Mayer and possibly copied by the Tycobrahe Sound Company. Rumor has it that Jimi Hendrix brought his Roger Mayer Octavio in for repair to Tycobrahe and that’s when they supposedly cloned it.This guitar effect pedal uses a small audio transformer to create the octave-up sound. Two germanium diodes and three high-gain silicon transistors create a screaming, yet surprisingly controllable fuzz effect.Controls:Level controls the overall volume. Because of the high gain transistors used, the Fuzz-O can get very loud. Use this knob to set a desirable output level.Gain controls the amount of overdrive/distortion. At low gain setting, the octave effect is more pronounced.ByPass engages the pedal on/off.Octifier engages the octave effect on/off. When turned off, the Fuzz-O is just a normal fuzz effect.This pedal has true bypass using a 3PDT heavy duty stomp switch. Powered by a 9V, negative post AC adaptor (not included), or battery. Includes reverse polarity protection circuitry.WORLDWIDE AND EXPRESS SHIPPING AVAILABLE!International Buyers: Standard shipping has NO TRACKING but a customs number. I recommend buying insurance $4.
