I know, these threads come up every day. I am selling my GK MB800 (long story), and will probably just replace it with a new one. I am also considering the MB Fusion 800, but am not sure I will prefer it over the regular MB. Also, the Tecamp Puma 900 and Aguilar TH500 are possible candidates. What I am wondering is have I overlooked anything? I am tempted by the Glock Blue Soul and Blue Sky, but both are a bit more than I am prepared to pay right now. This head will be paired with my Barefaced Big Twin T btw. And yes, I know that the GK offerings and the Aguilar are totally different sounding. With very few exceptions I have no problems getting tones I like from most any amp. Which is probably why I love my MB800 and my TC RH750 equally. I am not lurking or posting here as much as I used to, so please let me know if I have missed anything. Any high powered, micro heads beside the ones I have mentioned? Anything new from NAMM? Oh, and no ampeg. Thanks.
