Schaller Speed Knob 6,0 mm BC

Apart from the quality of the materials, these pot knobs are very elegant once installed. They are slightly smaller than the standard black speed knob (the plastic kind with the built-in number dial), and are much better for it. The grub screw means they are excellent for use on push-pull knobs - in many MANY hours of operation, they did not loosen at all. These were so pleasing, I believe I am unlikely to use any other brand again.

The original knobs purchased were a very early run and did not have the retaining screws included. Thanks to Thomann's brilliant customer service and knowledgeable staff I now have the complete knobs with screws...

These are solid and very heavy. The coating is extremely durable.

I am using these to restore a Westone Thunder Jet Bass from wrecked to hardcore monster (after a few modifications, especially a new matt black finish sympathetic to the original).

Very beautifull knobs. Installed them on Tremonti's PRS SE (sunburst). Now the guitar looks expensive.
They are very easy to install and comfortable for use. And the quality is high!
I recomend them, no doubt!

Very heavy, and reassuringly tactile. A nice feel under the finger which makes violining a pleasure.
