Nice! Where did you get your power supplies from as I'm looking to procure one for my bass? :D
maplins, 9v 600 mA...think they were £12 each, bit pricey really, can get them cheaper off amazon...weirdly, the bass and the keys only seem to work when they have batteries in, even if they're plugged into the mains...the beats works with just the psu and no batteries, but not the other two - I've checked all the psus and they all work, so am wondering if it maybe a fault with my units (they seem fine in every other respect) or just a weird quirk - maybe they are working from the mains but for some reason still need the batteries in place...I dunno it's weird...anyone else have this happen?
