Chickenhead style knobs and a good looking heavy duty cabinet with a closed back. I tie it together with a Fender Ultimate Chorus via the Fender's send and the Roland's return. Adds a lot of dimension across the room. Clean channel is extremely clean - no hiss or hum. Great truthful sound reproduction almost all the way through the volume range.
Overdrive channel is also noiseless, and sounds great.
I have a Fender Ultimate Chorus that everyone raves about how clean the clean channel is. This amp is much cleaner. I also like the overdrive this amp produces over the Zoom 505 effects pedal I use - very smooth. The amp has a nice tube sounding quality both on the clean and overdrive channels. I compared to several small tube amps and greatly preferred this amp over them all.
