I don’t remember, does a Fender have increased hum from old electrolytics when the amp is off standby, guitar plugged in, but amplifier volumes are all turned down? Or does that only show when the amp is in run mode with the volume/s up? I was going to grab my last and only tube amp, a ‘69 silverface Bantam Bass, and go sit in with my old band, possibly all night as they’re only a trio tonight. I think common sense is just telling me to leave it, and try to limp by with either my crate limo or Boss cube Street or maybe both. I’m sitting here asking this question when I ought to be double checking other things and not trying to force this... I just know they can get loud outside on a beach patio, and the solid-state battery amps that I have are going to be pushed hard possibly/probably to the point of throwing a speaker... I guess speaker upgrade on the SS’s is easier and better than frying The originality of the Fender, that is in line for a cap job anyway.
