The Davies clones are made of a more brittle plastic with a more dull, scratched appearance. Indicator lines and edges are sloppy.
The Marshall style knobs have deeper concentric grooves on the metal cap than the real thing. Just looks cheap in comparison. Same with the Boss style knobs. Plastic looks cheaper than the real deal in both cases.
I find the same thing with the davies knobs, especially the 1900H and 1510s. Mostly with the indicator lines looking like they're faded. The marshall style knobs were sloppy - rough drilled etches where the set screw is and some glue that overflowed when the metal cap was attached.
That being said, if only a small handfull out of every 100 are so bar that they're not usable, it think it's still better than paying 1.5-2x more per knob.
Are there any other sources for food quality, low cost knobs besides smallbear and mammoth (in north america, at least)?
I try to order my bare hammond enclosures from mouser when i make a parts order. it helps bring my cost closer to the threshold for free overnight shipping :)
