I gave Polytone a call on Monday and I just got a call back so here is the story on the head. It is a basically a mini brain and is 120 watts. It can handle a 4 ohm load, and it can be used as a guitar or bass head. The reverb and overdrive are for guitar but, the bass specific head and guitar head are essentially the same with different effects. I was told that this head was before the mini brain and was designed for guitar or bass.
