first, i did a search and could not find any discussion about this amp. i tried many setups today, in search for the 'right amp' for me. oh i tried the backline stuff, and some GK stuff, some 4x10 cabs,. 2x15cab and even combined 4x10w1x15 variating the pwer head from just about everything in the store. i was just about to give up, when i saw this 'line 6" 150w with a single 15. man, this amp will make ya cream.. very deep, tons of effects and presets. but the volume coming out of that 150 was amazing! i mean, c'mon, its so tiny...... and just wait, they have a 300w coming, i cant wait! so... i would like any comments on the 150 or the 300.. anyone tried it?? i want to use it for just about any show we come across. i think it will be loud enough, and light enough, and definitely cheap enough. the 300 list for only $599. thought??
