The 1 SPOT is the original 9V 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! The 1SPOT not only takes up ONE position on your outlet strip or wall outlet but also handles from one to over twenty guitar pedals (1700mA max!) and comes with a new heavy duty output cable! The 1SPOT can use its optional multi-plug cable(s) for powering more than one pedal and is 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, Morley9V, Zoom AD-0006. With its new converter plugs, the 1 SPOT will work with virtually ANY 9V pedal! ...even Line 6 modeling pedals and even convert international voltage (100V-240V) automatically; no transformer needed!
