I just bought a new Acoustic B450 bass combo amp. Great amp--punchy, lots of power, wide range of EQs, etc. Guitar Center was clearing these out and I received a floor model from an out of state store. The amp light won't illuminate. I slid out the amp and verified the wiring was connected, the two point harness was plugged in, etc. and I even spliced in another lamp assembly I picked up at the local Radio Shack. Nothing. Does anyone have an idea of what could be the issue? The amp works fine--just no visual indication of power. Acoustic has a nice 3 year warranty but there's no service location near me and I'd have to have it shipped out to have this fixed.
