* Note:

All Boss pedals have a sticker near the adapter jack, which indicates which adapter is needed. PSA pedals wants to see a regulated 9vDC adapter, while ACA pedals needs regulated 12vDC (the original ACA adapter was 9vDC unregulated, which turns out to about 12vDC at the loads these pedals put on it). Since august 1997, all Boss pedals (including surviving ACA designs) use 9 volts DC and are labeled ”PSA”.

Therefore, adapter listings that read ”ACA/PSA” means that if the pedal is older than mid 1997 (ACA sticker), it wants the old-style ACA adapter/12vDC regulated. If it is newer (PSA sticker), or if it has been modified to PSA specs, it works fine with the 9vDC PSA adapter. To find out (if the sticker isn’t there), plug your regular 9vDC supply into the pedal in question (alone, without daisy chain) – if the LED barely lights up, the pedal is definitely an ACA model.

Also, old (pre august 1997) ACA pedals will work fine from 9vDC, if they are daisy-chained with regular PSA pedals, and have signal cables connected between them. There’s a more indepth article about it here, if you’re so inclined. But whatever you do, do not confuse ACA with ”AC” – the pedal still expects a DC input voltage, and feeding it 9vAC will fry it.

A later version of the PSA adapter is the ”PSA-S”, with 500 mA capacity. This one is used for higher current effects, but will also work with lower current PSA-spec pedals.
