HB-20B : Great for a beginner

I got this together with the JB-20 as my first bass rig as a guitarist looking to explore the lower register.

This is a pretty good amp for a beginner. The sound is decent (and I think in my case a little bit held back by the pickups in my guitar). I was surprised to find that when used with a normal guitar, it produces a nice round and warm jazzy tone. The headphone output and aux in options as well as the built in compressor are a nice addition.

Two things that bug me about the amp are that

1) the eco mode (which can't be disabled as far as I know) demands a signal from the instrument input to turn on and will turn off after 30 minutes without a signal. This makes it less viable to use as a speaker for just the aux in.

2) the speaker pops loudly when turning off the power making it necessary to turn down the volume every time.

Overall, it's a great little amp for practice and beginners and I'm sure it'll last me a good while until I maybe decide to get more serious with bass.
