I am planning on getting the Avatar 2x12'' cab and was wondering which head would go better with it. (A more powerful head isnt really an option just because of money funds at the moment). I play 5 string fingerstyle rock, chili peppers and primus style funk metal, and jazz, I am big into variety, it is probably my main concern out of an amp. I like to dial a lot of different sounds, from bassy reggae to snappy. I think right now I am leaning towards the GK but even with Riks music it is still more then the Ashdown off the Avatar website. I am wondering if the extra money is worth it. Thanks for your input.
