Surprised by the tone. I purchased this as a backup for my Traynor lunchbox guitar head. Plugged into my 2 10 cab was surprising. Versatile tones and quite loud (my cab is 8 ohms). Good amount of headroom. Tone purists will notice a difference with tube amps. However, if my tube amp goes down mid-gig, I would have confidence running this little beast as a backup. Heck, run it as your main. It's lighter than any tube amp and the sound is good. Not tube good. But good enough.
