A 1 SPOT is the original 9V DC adapter that only takes up 1 Spot on an outlet strip or wall outlet. It solves an annoying problem that people have complained about for years! Only takes up ONE position on your outlet strip or wall outlet!! Handles from one to over twenty guitar pedals (1700mA max!) New heavy duty output cable! Use with optional multi-plug cable(s) for powering more than one pedal. Guaranteed to work with any equipment that uses one of the following adapters (over 90% of the effects pedals on the market!): Boss PSA, Boss ACA, Danelectro DA-1, DOD PS-200R, Dunlop ECB-03, Ibanez AC-109, Korg A30950, Morley 9V, Zoom AD-0006.** With new converter plugs, the 1 SPOT will work with virtually ANY 9V pedal! ?even Line 6 modeling pedals! ** Will even convert international voltage (100V-240V) automatically; no transformer needed! 3 meter (10?) cable is almost twice as long as other adapter cable.
