I use it mostly as a preamp for my 64 Custom Hand Wired Deluxe Reverb-Amp, and also as preamp into a Quartet audio interface for a digital guitar rig. The controls are clear and intuitive, 4 stomps and a 5 band EQ, helping to get the sound shape I want with added drive and presence. It allows me the use of phones that the Fender amp lacks. Be prepared for some noise, depending on your setting. But those who favor warm tube sound will appreciate none the less.
