2-Channel Mic PreAmp Tube Transistor

Here is a twist: two different and discrepant mic preamps in one box for two different colors. By popular demand, one channel is the exact same micpre as in our SLAM! with tubes and transformers. The second preamp is a fresh "No Tubes" design from Hutch and is inspired by old British console preamps with a tasty combination of "No Tubes" design with transformers. This one is not a clone of anything preexisting. It is a new flavor but reminiscent of that classic discrete sound. 
Both channels are designed around the basic goal of 'just plug a mic in and it sounds great.' The tube channel excels on traditionally difficult sources like some bright guitars, reed and brass, cymbals and some vocals. The "No Tubes" channel might be more suited for smoother vocals, drums, bass and raunchy guitars, but you never really knows which preamp is best for the job at hand until you try them. At least you'll have two qualified candidates in one handy 1U chassis.
