Vintage 1958 Fender Bassman tweed guitar amplifier

 

This vintage 1958 Fender Bassman amp with desirable 5F6-A circuit and tweed covering came through the shop a few years ago. I'm always a vintage Fender amp buyer but I especially love the Bassman model amplifiers from the 1950s. You can contact me here to sell a vintage Fender guitar amp.

The 5F6-A circuit was the pinnacle of the tweed Bassman's with updates in output and presence control. Jim Marshall was so impressed with this circuit that he essentially copied it for his early Marshall JTM-45 amplifiers. "Lilly" wired this amp at the factory in April of 1958 and her name is still visible on the small piece of masking tape on the inside of the chassis. Lilly's 1958 Fender Bassman 5F6-A was lightly played and wonderfully preserved throughout its lifetime. It retains all its original parts in good working condition except for a new leather handle, fresh full set of new old stock GE tubes and three prong power chord.

The amp plays nicely with strong output and very low noise even with original Astron filter capacitors. The circuit is fully untouched with original solder joints, capacitors, transformers, potentiometers, etc. The only modification was a properly installed three prong power chord for safety. The original Jensen P10R speakers sound strong with original cones. The chassis face is clean and free of pitting although there is a small area near the input jacks that is slightly bent. We chose to leave this for the next owner to decide whether or not to bend it back.The tweed is in nice vintage condition but does show wear on the bottom corners. It's clear that this amp was stored properly under some kind of cover since the tweed is still clean and not musty or dirty like most.

This clean 5F6-A tweed Bassman is in excellent collectible and playable condition without excuses or issues. The classic look of lightly worn but well preserved tweed is unmistakable compared to reissues or recovered tweed amps.
