Power amp for bass by GR Bass, it is described by the manufacturer as specific to achieve the highest possible fidelity.
Tested paired with Barefaced One 10 (1x10) cab and and Mosky Golden Horse (Budget Klon Centaur Clone) pedal.
The fan is active but decidedly silent, it also has ground lift and can power a 9v pedal or multieffect.
If you find something useful... you can consider to buy me a coffee:
