What is your opinion of this product?
I shopped a long time before deciding on this for my first tube amp. While it's the same size as my modern practice amp, the sound is larger, and the scope is so much broader. I was worried at first that I was trading features for sound, but I was amazed at the range available through the few knobs. It literally magnifies the range on my guitar's tone controls. Running my iRig Pro Duo through it, I get the best of both worlds. My digital pedals get warmth and growl from the tube tone.
