Was just noodling around the other day and hit on some tones that sounded surprisingly good to me, so passing along. Generally stay on the clean channel - and it's fine. But switched over to the overdrive channel and hit upon some settings that really sounded nice - surprisingly so for such an inexpensive amp. Warm, clear and bluesy. Put a big smile on my face and even my wife noticed the nice tone. So FWIW, this thing is a GTD 15R - SS, 12" speaker, spring reverb. Great little practice amp for very little money.
