This is a Marshall image model from the VALVENERGY series. Equipped with a Nutube, it realistically reproduces the raw sound of a vacuum tube amplifier while being affordable. If used as a preamp in a pedalboard, you can recreate the Marshall sound through the return jack even if you can't bring your own amplifier to the studio. Personally, I used to bring a head amplifier equipped with a Nutube to studio practice and loved it, but as a pedal-type preamp, I felt the usability had improved even further. I am selling it to organize my equipment, but there is no noticeable damage and it works without any problems. *Price reduction is not possible. Thank you.
