Three basic rules about Boss pedals (and one exception):
- If it says "PSA" on the bottom (or on the sticker next to the adapter jack), use a 9 volt regulated supply.
- If it says "ACA" on the bottom, check if it's produced before or after 1997. The easiest way is to plug in the PSA adapter - if the LED lights up properly, it's most likely a post-1997 model, and will work with the regulated supply. It may still sound best from an ACA supply (9 volts, then), but the difference will be marginal at best. By the way, the only ACA pedals produced after 1997 are the SD-1, BF-2, GE-7, OC-2, DS-1, PH-2 and CS-3. Most of these will have PSA stickers these days, by the way.
- If it says "ACA" on the bottom, and the PSA adapter doesn't light up the LED properly (or the pedal isn't one of those listed above), it wants 12 volts unregulated power to work properly.

Unless... you are using a daisy chain or power supply with common ground for all outputs (DC Brick, Cioks, PowerPad etc). In that case, the pedal will work with 9 volts, as long as there's a 'proper' 9 volt pedal in the chain with it. Some 12 volt ACA pedals will therefore actually work fine, as long as they are being fed via a daisy chain...
donc en clair : avec n'importe quelle alim 9v, une guirlande et au moins UNE pédale "PSA" dans la chaine, ça marchera parfaitement (en l'occurence ça marche aussi avec d'autres pédales que des Boss dans la chaine du moment qu'elles ont une régulation de tension du même type)
et encore une fois, testé et vérifié, si tu branches ta SD-1 "PSA" et tes autres pédales "ACA" sur la même guirlande, ça marchera parfaitement
