Very impressed! Top quality product delivered very quickly. It arrived to the US in less time than domestic packages do.

The Baby Sumo does exactly what I hoped for - plenty of clean power, completely uncoloured and no background hiss or fan noise. The construction is basic but seems robust. Inability to drive load impedance below 4 Ohms is an issue for me. A LED signal/peak indicator was added at my request.

Three things I wish the sumo had
A power indicator light on the front of the unit
An additional balanced input for XLR direct out from my bass amp. My amps send is only Pre EQ, but the balanced XLR out can be switched between pre and post EQ.
Volume Knob needs a white line so I can see where the volume is set.
Still 5 stars.

The power amp is just perfect. It is clean and loud in small size.

Love it! Simple clean amp with a high-quality build. The price is good and they shipped it directly after I placed the order. The amp is even a bit smaller than expected. I use it for bassguitar and double bass and for different styles by changing preamps. Only small remark is that the case is not very practical because such a small amp will go in one case with preamp, effects and cables. But to summarize: great amplifier!
