Hi GG&A, i just bought a fender blues jr from my local guitar shop and was wondering if i should be checking anything on it since it's used. it was a little dusty, but i've been playing it for a few days now and it seems fine.

i dont know much about tube amps so to be safe should i check anything even though it seems to be sounding fine?

i search barred and couldn't find anything so sorry if something like this has already been posted
It's always the last day of summer and I've been left out in the cold with no door to get back in
If you've been playing it and it sounds fine, it probably is. I would check the tubes to make sure that they are all working (they'll glow) and maybe check the pots to see if they're scratchy (does it crackle when you turn the volume/bass/treble knob). Other than that, just crank it up and enjoy.
