This is a great little power amp. It does need something in front of it to boost the input DB though. I received the following from GSS when I emailed before buying.

The Baby Sumo requires a preamp with at least +15dB of gain and an output impedance smaller than 10 K Ohm.

Its input is unbalanced.

There are a number of suitable preamp options. Anything from a $50 Mooer Graphic B eq pedal with gain or a One control Sonic Silver Peg, or Sadowsky SPB 2, or a more feature-rich Fishman Platinum Pro... will work fine.

If you want to get the very best out of the Baby Sumo, you can also use a high end studio grade preamp such as the Avalon U5.

I've been using this through a Fishman platinum pro with a pair of One10s and it's plenty loud enough for me
