Seems excellent so far. I've only briefly tried it in the house, but seems powerful, quiet noise floor and no fan. Input clip light fitted free of charge, thank you!

I was looking for this - a simple, clean power amp for my bass rig. It's quiet and lots of headroom. The communication prior to and during my order was outstanding. Highly recommend!

I have only had a few days to review it, but so far the power amp is a very fine piece of equipment. Totally quiet, works great, does not appear to "color" the sound at all. Which is just what I wanted. Looking forward to gigging with it later this week.

I haven't been able to test it yet, but the lunchbox is awesome, and the aesthetics immaculate.

Great power amp! It's loud, it's crystal clear and strong built. Did I mention that the amp is super compact and light? Well it is! I use it for playing bass wich works great. The solution for the bassist who works with preamp pedals and who dont want to carry a 19' poweramp around, or a whole bass amp only to use the power amp section. This amp will fit neatly into your pedalboard, next to your darglass (or and other) preamp pedal.
