what size screwdriver do I need to install these?

To install this guitar effect pedal knobs, you need a 1.5mm/0.06 inch hexagonal ruler.

I just ordered 20 of these. Can i get 10 of them white? There was no option to select upon purchase.

Hello, this product is 20 bags per bag, which is deposited and distributed by Amazon to the merchant, so it is not possible to choose two or more colors in a single bag.

Are these suitable to use for volume and tone knobs on a Gretsch?

The installation dimension of these guitar effect knobs is 1/4 inch (6.35mm). If the size is appropriate, I think it can be used for volume and tone knobs on a Gretsch.

How far up from the bottom of the knob is the screw located?

The distance from the screw to the bottom of the knob is about 4mm.

Higher Quality Than I was Expecting

I’ve had a lot of difficulty finding some replacement knobs for my Vox VT50 amp. I was really pleased when these arrived - the quality far exceeded my expectations, especially at this price. Honestly they’re nicer (and more effective) than the knobs they’re replacing.
