Anyone out there who owns/has owned both of theses brands? I'd be grateful to hear your thoughts on how they compare with each other tone-wise, particularly those who have experience with the GBE 750/1200, and TFA 550B/750A. I currently own a GBE 750, and though at 42 lbs. it's a pain in the ass to carry at times, I haven't found anything I'd rather gig with. Just wondering if Thunderfunk might be the solution, at least in terms of lower weight?
