sweet little thing that. Mine is a Fernandes FR15-B. I guess that makes it 15W. It says 40w on the back for the wall draw. The salesman told me it was B for bass, plugged it in and yep, it made a bass noise, sold to the raw beginner bassist who would one day become Downunderwonder the sometimes well paid semipro bass player's toenail. It still makes the dangdest practice volume oldschool rock tone I have yet to replicate at gig volume with any combination of GAS. I also enjoy tooling around on a little 5w tube open back guitar combo at lower than low volume.
So, OP, the moral of the tale is get a little combo of whatever wattage.
You should have some kind of classified local flea market activity. Keep your eyes peeled for little amps.
