Frequently Asked Questions

Yes, Palmer's isolation is effective – I’ve tested it extensively, and it genuinely eliminates ground loops and interaction between pedals.
Absolutely, the 250mA per output is plenty for most vintage Boss pedals, including the chorus. Just double-check the pedal's power requirements to be sure.
While it’ll work, some digital pedals draw more current; be mindful of the 250mA limit to avoid power issues. It’s best suited for analog or lower-current digital pedals.
