    True to my slight aversion to black boxes and housed in custom made 2U rack enclosure it's the complete Zagray! less PA.
    Including FX-loop and dual Master Bedroom Volume controls with their true log taper.
    Use FX loop Send output to feed your wet rig and normal output for the dry and still be able to use loop as volume boost function on the dry side.
    Just some of its unique features.
    Optional black handles are are available at no extra cost if polished brass isn't your thing ;)

    The first one is already on the way to its new home in Philly, PA.

    So I didn't let you follow the design process like in the original Zagray! thread. Well, I don't like repeating myself...I'd rather let others show their process too :)

    Beautiful work, Alek. I'm sure it sounds better than it looks. Paul

    Thanks Paul. The question is: will it sound better if you play through it with your eyes closed or open ;)
    You'll be able to judge for yourself at NY AmpShow in June. Hope to see you there.

    Cool, has a certain Steam Punk type look to it.

    Some day I would like to try one out.

    Congratulations Alek. I hope I get a chance to try it. Given the tone shaping capabilities on preamp on the Zagray, I've always thought this would be a brilliant product.

    Thank you my friends. This first one arrived safely in Jenkintown, PA on Monday.
    I'll have an identical one at the NY Ampshow in June so you're welcome to a test ride.
    Forgot to mention earlier, for the studio folks I'm working on optional tube driven transformer balanced line output.

    Beautiful. I missed the original thread but I am seeking a world class 2 channel preamp to replace my Kasha Rockmod II in my big L.A. Sound Design rack. I am looking for something that will go very clean for the ambient/textural soundscape stuff I am doing now with the Eventide DSP 7000 and Eclipse but also give me classic prog-rock/Gilmour-esque sounds. Would love to hear more about this preamp in that role?

    Wes, my friend, we never got to those beers last August in Nashville. Better luck this year?
    Guts for your viewing pleasure:

    No Wes, that little blue cube is a transformer for 5V regulated relay supply.
    Wonder why the front panel in photo above is unscrewed from the case?
    It's to make any future servicing easier. And if there should ever be a need to work on the main PCB: just fold it up!
    You haven't seen that one in a guitar amp before, have you?:banana

    Actually, that's exactly how I designed our amps to be serviced! 6 front panel screws, 8 PCB nuts and you can have the whole circuit right there in front of you...takes about 1:30 to get the whole thing apart.

    Excellent looking box Alex!
