Junior reverb amp

The Junior Reverb amp is targeted for home and/or studio use.

It is ideal in both these places due to its low wattage and small size. It is not that heavy and is loud. It is a very versatile little amp that can deliver 4 watts to 10 watts of power through an efficient 10" speaker. 

It is a 1 channel amp with a small sized true spring reverb by accutronics(r).

It has a Bright switch and a Gain control that "raises" the incoming gain of the signal.
It also has a Master volume which along with the volume control you can go from very clean sounds to very "tubey" overdriven ones.
