The unique appearance of the pickups comes from part of the process which creates them - the units are resin cast, eliminating the need for any form of cover. The humbuckers are built in a rubber mold into which the magnets and coils are inserted, a special aerospace grade resin is then pored over the entire thing, resulting in a perfectly sealed and shielded pickup.

'Aqua Blue HufGlow' is an expensive material which contains a unique proprietary formulation which consists of 'strontium aluminate' doped with some 'rare earth elements' such as 'dysprosium' and 'europium' which makes the glow last longer than any aqua blue pigment available on the market, this unique material which has a 60 years lifespan is also non-radioactive and non-toxic.
All my current guitars are fitted with a rare 'NOS' Russian military 'FT-2' 0.022uF or 0.027uF TEFLON capacitor! I believe that I am the first guitar builder to be using TEFLON capacitors and have therefore copyrighted the concept ©Uy6VlWI7gk3Y2Ejc
