Musiclily Pro Boutons Universels en Plastique pour Guitare, Basse, Ampli, Pédale d’Effet, Amplificateur, Lot de 12

Visually looked good.Not universal for fit.Too small ID (inner diameter)And too shallow depth.If they are too hard to push on, you could damage the potentiometer.

Great price. Perfect fit on my tube amp. Gives it a classic look and the plastic is thick, durable.

First off this was more a fit issue for me, they just didn��t sit right, the second was quality, if it had been spending a couple of pound I might have been more biased towards oh well you get what you pay for, however these were not in the cheap range and I expected all of the knobs to be of the same quality but the finish where they are painted to indicate the level mark or pointer was poor, one knob had paint marks all over it.
