FIRST, let me give you my parameters so we can try and keep this thread on topic. - I CANNOT buy a 4x10, or lug a 4x10, or anything big due to space limits in my car. - I have absolutely no need for more than a 2x10 when at home practicing, I just want the 2nd cab for when the Drummer and Guitarist are part of the mix - I am going to be using Mesa Boogie's new Eminence based Powerhouse cabs with a Strategy 88 head. - I will not be playing extraordinarily loud, or with any overdrive, or anything more than compression and EQ. My main goal is clear sound, with lots of overhead. - I play clean, generally prefer brighter tones, mids scooped, clean low's both finger style and slap, no pick. The question is do I go with a 2nd 2x10 (400w), or will I gain something from a 2nd 1x15" (600W) cab? The 1x15 is marginally more money, slightly bigger and heavier, all strikes against it.. but as I've only been able to hear it once, my memory of the tone was that it was "big" and not as defined as the 2x10 tone... was I just having a bad day? Keeping the above in mind, what would you get and why?
