This is a super cool little solid state combo amp from the 1970's. It has been fully tested and is working well. The amp has a great sounding tremolo circuit as well as a funky spring reverb. At full volume this amp has a very lo-fi overdrive tone that is in the Queens of the Stone Age realm making this amp a great studio addition for recording. The manufacturer, Prince Tsushinkogyo Co. Ltd., was founded in 1950 in Nagoya, Japan. They concentrated on making tuners and solid state musical instrument amplifiers which were sold under the Prince brand names as well as others (such as Memphis). The company began to use the Arion brand name in 1980 and began making guitar effects pedals. The company's fortunes declined in the 1990s and by 1997 Arion was sold to the Ueno Kaihatsu Center, who continued making pedals and tuners, but discontinued the amplifiers.
