I have recently decided to buy a Line 6 SpiderII 112 combo (75-watt). I am wondering if this is a decent amp to acually buy. I have played on it at my local guitar shop and it has a very decent sound for the price of $300. I noticed I can buy a pedal with it, but that only that kind of pedal is compatible with the amp because of the hookup. Idk if this amp would be anygood or loud enough for smaller performances, but right now im not in a band but want to get this one for a practice amp. Currently I own a Roland 15-watt cube. I dont hate it, but it doesnt have much to play around with, and it does keep up with a drumset at louder volumes, but I want to get the more powerful one to keep up a little better.

If anyone can tell me more about the Line 6 amp IM looking at, I want to know if it is really worth the buy, if I can use any other pedals or effects with it and how, and if it would be good for performing.
