I use one in a band, volume wise it works but begins to break up with some basses. I found a used Fender Bassman 70 at GC and it’s a beast (and cheap, 70 bucks! But too heavy for me to lug around so it stays home. If you are ok with lugging around a heavier amp, do so but if weight
is a big issue, then by all means the GK is fine. Also check out the Fender lightweight bass amps as well to compare. I don’t think the GK is the best tone, it’s a compromise IMO.
