I just purchased a very lightly used TLM-103 from a friend to replace my wonky MXL V6. The Marshall is fine for it's price but it took a nasty tumble and now has a lovely dent. After about 5 or 10 minutes it will just decrease in volume until eventually it's dead quiet. I borrowed the TLM from a friend who didn't care for it too much and after some wheelin' n dealin' wound up buying it from him for a VERY decent price. So now I've got a much better mic but there's a new problem: My ART TPSII pre. It's gotta go. I'm looking into either the Summit Audio 2BA-221 or GT Brick...something that will function well as a good, affordable high gain mic pre/DI. I will be recording solo male vox and acoustic guitar mostly with the occasional electric bass/guitar. I can get either pre for about the same price, give or take $100, and both seem to be pretty evenly matched. I'd prefer something with a little attitude to it (I think the nod woud go The Brick here) but I really like the Summit Audio's solid state and tube configuration. Tough choice. I'll alternate between the TLM-103 and an SM58 most of the time. I'm not looking for a surgically clean signal. Wanting something a little warm thats able to be pared back for a cleaner sound for some projects. With the mics I've got and the sort of signal I'm trying to get which pre would you recommend and why?
