I have a complete LINE 6 Spyder 100 watt amp. Works decent with some minor knob issues. I have the pedal board from LINE 6 too! It has an electrician installed, speaker plug out for two extension cabinets. SOUNDED AMAZING at outdoor concerts! Been considering taking one of the speakers out to build an extension cabinet for a MONOPRICE 15 Watt 1 12. Would consider selling the other one, and parting out the rest of the amp. Or could make a great offer on the whole amp, with part, or all of the cost paid with a nice 30-40 watt speaker. Reach me at 316-204-0800. Bill
