The One Spot 9v DC adapter 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.
Will even convert international voltage (100V-240V) automatically; no transformer needed!
3 meter (10′) cable is almost twice as long as any other adapter cable.

Will the 1 SPOT power my pedal?
If your pedal can operate with a single 9V battery, yes.
If the power jack on the pedal is labeled 9VDC and uses less than 1700mA (virtually all pedals use far less current than that), yes, the 1 SPOT can power it.

The 1 SPOT is 9VDC (not AC), with a barrel-style output plug which is centre negative.

The Converter Plugs (CL6, C35, CYR, CBAT) allow the 1 SPOT to work with other types of DC power jacks and/or opposite polarity.

Most pedals use the barrel-style power jack with the polarity described above. For most others, one of the 1 SPOT Converter Plugs should make it work.

If your pedal requires 12VDC, 18VDC, 24VDC, or any voltage shown as AC, the 1 SPOT will not power it. (You can try a 1 SPOT with a 12VDC pedal, but it might sound a bit different. No damage will occur.)
The only exceptions are some Line 6 pedals (like the DL4, etc.) which show 9VAC on the pedal, but can actually be powered by a 1 SPOT with a CL6 Converter plug attached.

Occasionally, some pedals do not share power very well with other pedals, but this is rare.

In most cases, you can link your pedals with Multi-Plug 5 or Multi-Plug 8 daisy-chain cables, having all of them sharing a 1 SPOT.

If you have a fuzz pedal that uses germanium transistors, it probably cannot be used on a daisy-chain cable (MC5, etc.) with a 1 SPOT. It would need a separate 1 SPOT just for that pedal.
