Modular power supply
A clever, scalable way to power your pedals! Each one of these modular power units supplies stable power to five pedals. Need more outputs? Just plug on another one of these for five more! Now you can adapt your power supply capability when switching between different pedal rigs, for home practice, rehearsal space, studio or your go-to live rig. This unit provides five isolated, short circuit-protected, filtered outputs at 9/12 V for plenty of flexibility. The outputs even have a handy LED, so you can see which outputs are in use. Yup, we’ve pretty much thought of everything…
