I settled on a Blue Colander Tremond - it's an LM308 driven Rat with a clean blend and LPF control. It also has a switch for various clipping options.

Just noticed that Thomann are listing the T-bird's specifications with a "Blackwood tek" fingerboard instead of the rosewood that was originally specified. Perhaps this accounts for the recent price increase?
Anyone have "hands-on" experience?
