      Comments about SM Pro Audio TC01 Single Channel Tube Preamp:

      I've been using the two channel version for years in my studio and love it! Great transparent sound and I like the front 1/4 inch inputs for keyboards or some other mics. The optical compressor is subtle and easy to operate. I run everything through this processer. Great for the money!
