This amp has been assembled with a dovetailed pine cabinet that has been carefully stained and finished with clear coat poly. It has a brand new Canabis Rex speaker and an aftermarket mod reverb tank. The chassis was pulled from a 2001 "cream board" Blues Junior and has NO circuit board mods. I assembled this amp intending to use it in my home and keep it for many years but unfortunetely I must sell it due to unexpected financial reasons. All of the component upgrades have been well researched and are generally considered to be the best match for ideal tone. This little amp sounds amazing and is better than new.
