This auction is for my Ibanez 1980s Made In Japan Flanger serial number 166771. I have owned it from new and it has picked up a few chips and scuffs as can be seen in the photos.It is in full working order and produces warm, analogue, full bodied lush sounds based on chips they don't make any more. It has controls for speed, width and regen. Quite rare now and highly collectable. Any questions please ask. Grab yourself a vintage Gem - Good luck and !
