Got some custom knobs made for both the R331 and R701 Clippard valves. I've always loved the look of the vintage valves. The beveled edges of the knobs just looked awesome and I wanted it very badly. Unfortunately finding vintage valves are next to impossible so I got them custom made and they look fantastic! Spot on and made to fit the real Clippard valves.
The 701 is a single screw on cap while the 331 is an actual assembly of several replica internal parts. It even still has the ability to screw up and down.
Here is my original old/new stock R701
Here's my R701 with custom knob.
Here is an original Vintage R701 for comparison. See how close it is! (I forgot who's image this was so I'm sorry)
I don't have a clear picture of a vintage R331 but you can see on screen stunt packs that the R331 has the same vintage beveled edge.
Here is how my R331 looks with the custom knob.
Here's a look at the replica assembly next to the original assembly that was in the R331.
He did such an awesome job with them can't thank him enough!
