I currently own a Marshall AVT150/AVT4x12 and Fender customized Strat. I'm looking into buying a Mesa Rectifier half-stack for myself to play, and also to furnish my studio. I do however have a question. Im hoping to fill the gap in my knowledge of things here. I am almost positive that the Triple Rec(150W) head is overkill and pretty much a waste of the extra $$. That leaves me with the Dual and Solo. Is wattage the only difference between the 2? And if so, what factors should I be thinking about when deciding on 100W or 50W? Also, what would you recommend on the Cab? Im going to go with a Mesa 4x12 but they offer an oversized and a regular sized. I have no way of testing them side by side and the descriptions I have read of the 2 cabs arent very helpful. If for no other reason, I was thinking of getting the regular cab just because it matches the size of the head in width (Stupid reason I know, but aesthetics do matter a little bit.) Anyway, all suggestions are welcome. Thanks!
