I needed a small, simiple, versatile grab-and-go amp with great sound for practicing and small gigs. If you have a gig bag with a big pocket, this will fit right in your gig bag. This amp fits the bill perfectly for me. The mp3 input is great for practicing, and we also pump our iPOD through it for music in our house. I throw this in my gig bag with my cables, carry my light 2x10 cab, and I'm good to go. In and out of every gig in 1 easy trip!
The EQ section is simple and pretty idiot-proof. It's easy to dial in a great sound. The gain boost/pad switch is nice for active vs. passive pickups, and the mute switch is a good touch. I don't use the on board tuner too often (SNARK tuner or my ears usually do the trick, but it's nice to have the option. My soundman has commented on how good the amp sounds. The amp has a sturdy feel to it....more than most other amps in the micro bass amp category.
The toneprint is a nice feature, and I have enjoyed it a LOT. For gigs, I like a little compression with some tube warmth/grit. Some of the combined toneprints do a decent job on that front. It has been fun playing around with choruses, flangers, vibrato, compressors, octavers, etc. They all seem to work pretty well.
My only complaint, and the reason for 4.5 stars would be the lack of a separate gain control and a tube preamp. There's just a little something that a tube adds to the sound that would be nice on this amp. For value, you can't beat this little beast. It's certainly loud enough for anything I would need unless I'm playing in a stadium (which will never happen).
