    A Starter Anyway!

    Comments about Alto Alpha MICtube 2-Channel Preamp:

    For the price, this is an okay value. I purchased it mainly for the phantom power and to experiment with something hardware driven as opposed to plugins. Change the 12AX7 Russian tube if you can! I put in an antique RCA 12AU7A with much better results. There is a lot of his when it's really driven. I'm saving for a Focusrite or Avalon.

    I truly must say that the purchase of this unit for my home studio was one of the best investments I have ever made. I am very pleased with the amount of warmth I have added to my home recordings! I want one more, then I will have a channel for all of my mics. GREAT VALUE!! STEAL DEAL!!

    amazingly drops price

    Comments about Alto Alpha MICtube 2-Channel Preamp:

    this is a fine example of Chinese craftsmanship. Only one tube, -20 pad doesn't work on channel one. However, a unique crunchy sound. Really only worth about $50 bucks.

    neat but noisy

    By scrubs

    from Winston-Salem, NC

    Comments about Alto Alpha MICtube 2-Channel Preamp:

    have had this for about a week. i like that it has 2 channels for recording in stereo. there is ample gain on each channel and the mixable tube drive does add some presence. however, when either dial is past 12 o'clock, there is significant hiss, even with nothing attached. functional as a di for bass.
