Report Review for product Knobs - Marshall, for Amplifiers, push-on

I have purchased a number of these from Amplified Parts. The knobs are very good. I have purchased both push on and set screw types. A number of the set screw type knobs were knot drilled and tapped correctly and they actually did not work and I had to discard them. I now only use the push on knobs on my audio projects as they are 100% OK.Amplified Parts and (the other company located at the same address) are TOP NOTCH companies. I am a ham radio operator/builder and a audio component builder so they are just about the best place to buy parts. The Push on knobs are great but shy away from the set screw if you can!
