Be sure to add me to your favorites list Irin Fully Analog Flanger Guitar / Bass Guitar Effects Pedal, Great Analog Sound with a True Bypass Switch, As-New Condition with Box and Manual ... with Added REAL, LARGER KNOBS! This is an as-new condition Irin Flanger Effect Pedal for use with electric, bass, and other type guitars. It is in as-new shape, with one major improvement ... Larger Knobs that are much easier to use! Mini Pedals are great, but the tiny knobs they come with aren't, so I fix that on my pedals and here's one in as-new, open box shape for you to grab up! This is just for the pedal itself (with modified knobs), it's box and the small manual included inside as well. No power supply or any other cables are included. This pedal has standard 1/4" input and output, adapter input, and 4 Dials that control Width, Speed, Delay and Regen (feedback). It has a nice brushed metal case and a true bypass switch. This one's extra special due to those nice Davies type 1900 style knobs, black in color. Be sure that when you use it, use a 9 volt power supply for use with guitar effect pedals, that has a Negative center polarity, as such ... By using a classic BBD simulation circuit, this flanger can deliver a deep and rich tone. The four controls Speed, Regen, Width and Delay allow you to shape your desire sound., from dynamic jet-plane effects to space effects to short delay, wave-like chorus and vibrato sounds True Bypass: Minimizes signal loss Power Requirements: AC adapter 9V DC center negative plug (not included) Thank you for looking!
