  • 100–240 V 50/60 Hz input works worldwide without a voltage converter
  • 6 ft cable lets you position the adapter away from the pedalboard

Compatible BOSS Roland pedals

This AC adapter powers a wide range of BOSS and Roland multi-effects units including the GT-10, GT-10B, BCB-60 and PSB-1U. It also supports many compact pedals such as the DS-1, DD-3, CE-2 and GE-7. The 5.5 mm by 2.1 mm barrel plug fits the standard centre-negative input on these devices.

Thermals noise and power draw

The adapter accepts 100 V to 240 V input at 50 Hz or 60 Hz and delivers a regulated 9 V output at 2 A for 18 W total. A built-in magnetic ring suppresses line interference while the intelligent protection chip provides overload, over-voltage, over-temperature and short-circuit cut-offs. The unit runs at low temperature during normal operation.

Output specification that decides fit

Output is fixed at 9 V and 2 A with a 5.5 mm by 2.1 mm centre-negative barrel connector. Buyers whose pedals require a different voltage, a higher current or a 2.5 mm inner diameter plug cannot use this adapter. The six-foot cable length is also fixed and cannot be changed.

Questions about this item

How do I connect the 5.5 mm × 2.1 mm barrel plug to my pedal, and what polarity should I check?

The plug fits the 5.5 mm outer / 2.1 mm inner jack; the inner sleeve is negative and the outer sleeve is positive, so match the pedal's marking before plugging in.

Will the 6 ft cable or the anti-interference magnetic ring need replacement over time?

The magnetic ring is a passive ferrite bead with no moving parts, and the cable is fixed; neither is designed to be serviced or swapped out.

At what load does the overload cut-off engage during a long rehearsal?

The adapter is rated for 9 V at 2 A (18 W); the internal chip cuts power automatically if the draw exceeds that limit.
