Authentic Marshall quality

If you need to replace a lost or broken knob on your gear, this is the one. The detailing on the logo is crisp and clear.

Good value

Nice aesthetic upgrade for my DIY pedal project. The plastic feels durable enough for regular gigging use.

Great look, tight fit

Looks exactly like the original. It was a bit tight to push on initially, but once seated, it feels very secure. Happy with the purchase.
