Great ac/ac adapter for a reasonable price with a 5.5/2.5 mm secunder plug. It's larger than a boss adapter, but you get a safely enough current capacity. The cable is a little bit thinner than the avarage, but if you take care, it's not an issue. I bought it for my digitech xp100. Works perfectly. Muziker sent the bulletproof packet cheaply to a practical pickpack point in a very short time. Thank you Muziker!
