I'd like to pick up an adapter for my Boss tuner pedal. The Boss adapter (PSA-120S) runs about $18, but I can get a Dunlop ECB-003 for about half the price. Any reason I can't go with the Dunlop and save a few bucks? Thought I would ask before taking a guess and damaging my pedal. FWIW, I don't run a pedalboard or any other pedals/effects; just the Tu-2 as a standalone unit. Thanks!
