I put these knobs on my SG volume controls to distinquish them from the tone controls. Helps a lot when doing a gig in a place thats not well lighted. I really don't need to look at the knobs, I can tell by the feel of the larger diameter that they are volume controls. Knobs fit perfectly.

great product

I wanted to try these off brand knobs (black speed knobs) because the Gibson knobs are unavailable and very expensive. I ordered 4 knobs and all of them were heavily scratched. I contacted AES and they would not allow me to return them. They wanted me photograph them to prove that they were scratched before they would refund my money. I did photograph them and they only refunded the price of the knobs. I complained and they did finally refund the shipping as well. This has been a bad experience and AES has lost a long term customer because this was so hard to resolve.
