do you mean a power adaptor? Im not a wise man so Im not sure what you're asking. If its a power adaptor you can get ones from DSE that have variable wattage (or is it amplitude?) and they're less than $20. The come wiht all different sorts of plugs so they can fit into anything.

ignore the label that says only use boss adapter. most electronical stores sell things that do the trick. just gotta match the volts and amps and polarity. if you dont know how to do that just take the pedal and they will sort you out. may cost you $30 or so for a cheap one. are you getting it just for the ds-1?ds-1s dont suck much power at all, the batteries last for ages. i got one for a metalzone which is digital and sucks power. if youre going to get more pedals, it may be worth getting a more expensive adapter which has more current or something so it can drive more pedals.
