    Very pleased so far with this amplifier. It is perfectly suited for my needs as a violinist and it came with an extra UK mains plug. I am not an expert in any way but this is simple to use and has a powerful sound.

  • Steve


    This is a really great keyboard amp. I'm so chuffed with it.

  • Alastair


    A very good product in excellent condition. My only complaint is that it came with a power lead with a US plug on it and a rather bulky US/UK adapter. I know you can get a proper UK power lead as I also have the smaller Ultratone 450 and that came with a UK lead which in fat I am now using wit the 900.
