  • Ruby 12AX7A Tube in an ART MP Studio Preamp

    As reviewed by Steve Szabo on 4/22/2014

    My 2nd Ruby Tube in my preamp. Better than stock tube, smooth tone, good for playing music from computer and for amplified MXL 990 Microphone input into ham radio. Lasted about a year or more with a lot of use-long life.

  • In Spite of all the danger

    As reviewed by Merrill Guice on 7/25/2013

    Ordered at the same time I ordered a heavy duty mike stand. They just tossed it in the box and it was rattling around in there when I opened it at the local Guitar Center. The sales guy's eyes were big as saucers when he saw that. Just a word of warning: Guitar Center seems to treat the 6 month manufacturer's guarantee as carte blanche to save money on packing. Oh yeah, the tube worked fine in the little ART Mike Pre-amp (the cheap one) and a lot of noise went away.
