Q & A
Question: Peut il être fonctionnel avec la pédale boss ve-22?
- asked on Feb 19, 2024
- asked on Feb 19, 2024
Question: Is this the power adapter for the BOSS ME-90 multi-effects guitar pedal? If so, I'm curious how it would work, considering the pedal's battery pack is 4pcs (6V) while the adapter is 9V. Normally, the battery and adapter should have the same output.
- asked on Sep 13, 2024

Answer: This is the recommended power supply despite the difference in voltage rating. Its circuitry likely reduces the 9V PSA voltage down to the 6V required.

Question: Is this compatible for use on a Zoom B3 Bass Effect pedal?
- asked on Dec 5, 2024
- asked on Dec 5, 2024
Answer: We recommend the ZOOM AD-16 for this unit, but the Boss could work.
The B3 would be at the very high end of it's output capability.

J'ai acheté un Sound Canvas SC-88 VL probablement aux alentours de l'an 2000. Son PSA-1208 vient de flancher. Y'a pas à dire 25 ans c'est très bon. J'en ai aussi un autre qui alimente en même temps 5 pédales Boss et il peut sûrement en alimenter plusieurs autres. Très bon produit. Le prix est un peu élever mais considérant la qualité et à $1,40 par année d'utilisation ça en vaut le coût.

You can't go wrong, this is the real thing for Boss/Roland and lots of other 9v powered gear. I've used it for Ibanez and DigiTech pedals also. Just make sure it matches the requirements of your gear. Nice bright LED and 10 feet of cable is tons, top marks. It might be a 5 star product if not for the hefty price tag, and the bulk of the cable... not sure what that cocoon thing is but it's annoying. Also, they say "won't cover adjacent power outlets" but in my case that's exactly what it does.
