Good but tight

Quality is excellent, but it was a bit tight to push on. Make sure your shaft is straight.

Solid construction

Heavy enough to feel durable. The anodized finish matches my black amp perfectly.

Sleek upgrade

Replaced the old plastic knobs on my pedalboard. The aluminum feels much more premium.

Perfect fit for my Fender amp

Looks great and fits snugly on the 6mm shaft. No slipping during use.
