Power for the BOSS GX-100
It draws 800 mA at 9 V. Most pedal power outputs are rated lower than that.
These supplies have an output rated high enough.
| Supply | Outputs that carry it | Rating of each |
|---|---|---|
| MXR Mini Iso-Brick | 1 | 800 mA |
| Truetone 1 Spot Pro CS12 | 1 | 800 mA |
| Truetone 1 Spot | 1 | 1700 mA (1.7 A) |
| Cioks Crux | 1 | 2700 mA (2.7 A) |
| Pedaltrain Volto | 2 | 2000 mA (2 A) |
Unless an output is rated at least 800 mA at 9 V, give it its own adapter.
Will the BOSS GX-100 fit on your board
Width must fit inside the frame. Depth may hang over the front and back by up to 5 mm in total. A treadle pedal is never turned sideways, because you rock it with your foot.
