Great smaller knob. Fit perfectly on the pedal I needed them for. Fit solid shaft pots perfectly and look great!

Brass insert with brass screw.

Deducting a star because brass screws break easily. If I ever need to remove the knobs some will be very difficult because the screws broke. Steel Allen Head grub screws would make this a 5 Star knob.

Nice small scalloped edge knobs...with...brass inserts.
Great upgrade for some older pedals with no so great knobs.
If you are familiar with the Marshall Echohead, Regenerator etc style pedals then you know the stock knobs are pretty lame. They come with polished chrome knobs with small painted black lines. You can't see where they are set even in perfect lighting and they have some funky press on friction mount that spins, breaks.
Enter these nice plastic knobs, with clearly defined indicators, brass inserts, and set screws! And, color coordinated with the pedal labels. Lots of colors to choose from too. The only mod I had to do...and this was another Marshall goof...was the mode selector position one. The pedal posts were not round and had a cut out that did not line up, so I swapped a longer set screw from a pedal topper that was longer....perfect.
No issues with these new knobs...goid solution to a bad stock knob design.
See pics!

Really great knobs. The "Clear" ones are crystal clear!
