This is definitely a rare creature. Personally, I have never seen one before so I'll do my best to describe it. What we have here is a 90 watt, Polytone Mini Brute PA system that sports 3 channels with bass, treble, volume and reverb for each channel along with a switch with 3-way Bright to Dark controls. All 3 channels work and the cabs have been tested. It's a very cool little rig. When I received it, it didn't power up so I took it to Aztech in Watertown, MA and they did their magic and spruced it up. Now it's time for somebody else to enjoy the legendary cleans of a Polytone amp. Imagine the fun you and 2 other jazz greats will have playing through this setup.
