Jome,
I'm glad to see you back on the Thunderfunk wagon! The 550 I got from you has been gigging ever since I bought it. I use the 550 for all rehearsals and use the 750 for the shows. I still take the 550 for my spare. Great head, hasn't missed a beat!
One of these days, I'm gonna send my heads to Dave to get them upgraded. The problem is, they are doing such a great job, it's hard to justify right now.
Glad to hear that you're still digging the TFunk. I sure hated selling it and the Berg cabinet but I'll have to say that the Roscoe 3006 lived up to my expectations
It sure was a bit hard finding another nice clean 550-B though. Not as many for sale these days (although I've seen a couple of the last few weeks).
I'm set for basses and amp/cabinets now though so all's well that ends well!
