Been using the "tank" gbe 1200 for a few years now. Love everything about it but the load outs etc.... I'm ready to go lightweight although I'll be keeping the gbe for backup as I've never had an issue with it or the GBE 600 I had before. Been using strictly GB gear for almost ten years now. Never had to call the factory for anything.. I'm a fan for sure. I usually run one gb 2X12 but occasionally bring two. I've never turned the volume past 3 with the pre gains set at 12 oclock, so obviously the gbe has been way overkill for my needs. Whats the closest tonewise in the GB lightweight line up, keeping in mind I'll need 2 ohm capability from time to time? IS the shuttlemax 12 my only option for 2 ohm loads? I like the idea of "bi amping" with the stl 12 but something just rubs me the wrong way about these new fangled lightweights. I don't really trust the reliability, but I don't really trust my back when I'm hefting the big boys either. That dang head weighs more than my cab! Any feedback from folks who went from the GBE to some skinny skank and was OK with it? Play mainly funk and reggae with a Thumb 5er.
