Your vintage Fender amp needs a dry room and regular use.

Yes, rust and tube issues are mostly about humidity and neglect. Julia Jacklin’s touring amp gets played hard and kept dry — that’s the secret.

Rust forms when moisture sits. If you live somewhere humid, store the amp off the floor, use a dehumidifier in the room, or at least put a silica gel pack inside the cabinet. Don’t cover it in a sealed plastic bag — that traps moisture. A breathable cloth cover is fine.

Tube problems come from two things: cold starts and sitting idle for months. Play the amp at least once a week for 20 minutes to keep the capacitors formed and the tubes warm. When you power it up, let it warm up in standby mode for 30 seconds before hitting play. And never move the amp when the tubes are hot — they’re fragile.

If you see rust forming on the chassis or transformer, clean it with a little WD-40 on a cloth (not inside the amp, just the metal surfaces). For tube pins, a pencil eraser works.

Vintage Fenders are tough, but they hate damp basements and long naps. Treat it like a guitar you actually play.
