I've said it before, but with all the "rah rah D-Cline is awesome!" going around, I'll reiterate my experience because it was 180 our from Shane's.
Message sent on on facebook and then email, crickets for days. Finally, "Oh hey, yeah so I don't get back to anyone until I have enough messages to make it worth my time." Then, after telling him what I was looking for (sienna burst, spalted maple) he suggested some orange acrylic knobs. I told him no. He then said, "Well, I can do the ORANGE you want."
Full stop. A Roscoe custom that ran north of 4K and he wants to suggest 100% acrylic knobs in the wrong color? Me: What kind of amateur am I dealing with???. He still wasn't sure of the amount or type of knobs I needed after multiple communications telling him so.
So just be aware of what you're getting into if you- he's an amateur, running a side business, and my experience was enough to turn me off and not buy the knobs.
I was expecting the Keith Roscoe of the custom knob world. That was not who this guy was.
