Amp. Thoughts on Pignose?

In particular the Pignose 7-300 HOG-30 Amplifier.

I have the 15 watt pig nose that I use for practicing bass quietly with my upright electric. They aren't real loud but if you use a preamp they are much louder. I use a Sansamp para driver DI. The battery holds up quiet well too. I think the longest I've gone without charging was a little over 3 hours

The 15 watt one works out nicely for bass? Very good to know.

I'm not good enough to want anything loud yet. I just want reliability of gear and nice tone.
