[Harp-L] Gaskets for Special 20, Lee Oskar, and Seydel Session Diatonic Harmonicas

[flyingv8@xxxxx]

That sure makes sense Vern and I almost abandoned this project. Then as a last attempt to prove it out I put gaskets on a Special 20 and mixed it in with other Special 20's and dared myself to find the gasketed harp. It didn't take any time at all. These were all stock harps and all played pretty much the same. Let's wait and see what other players think ok?

Assuming combs and plates that are not egregiously warped, the amount of air escaping under the plates is minuscule compared to the amount escaping around the opening reed. Gasketing or grouting the plates is like weatherstripping the windows in a room with an open doorway.

However, I have never encountered a leakage problem with undamaged combs or plates. Any opening that can’t be closed by snugging the plate screws will be visible.  In that case, a gasket is not the best remedy.

The gaskets (2 per harp) seal between the brass reed plate and plastic comb. They are made from .005 thick foods grade ptfe and are washable/re-usable and will not mold. I have had several people try them out as well as testing them extensively myself over the past 6 months and all have seen a noticeable improvement in the harps response. I want to offer these to the community for free for a short time to get a general consensus. If you contact me through my website with your address and type of gasket you need I will send 2 at no charge. I have never been a Lee Oskar guy but after putting the gaskets on I love those harps. I am really excited about this and I think you will be amazed at the difference! www.deesfti.com
