A close up of the guitar side looping footboard. From top to bottom: Upper deck left side ADA FS-2 - controls bypass and repeat hold functions of the ADA Digitizer 4 delay unit. Upper deck right side - ADA DS-4 allows choice of 1 of 4 delay presets. Middle deck - Boomerang looper pedal. Lower deck from left to right: Off/On for TC Electronics 1210 / Bypass for ADA Digitizer 4 / Repeat hold for ADA Digitizer 4 / Bypass for guitar M2000 / Bypass for vocal M2000. I made the lower deck out of an aluminum door threshhold I found at Home Depot - looks very nice I think.
