Specially designed as a direct upgrade for standard Rickenbacker® 4001/4003 bass guitars the ThumbChum® is made of 5mm clear acrylic and can be installed without any additional drilling to provide a thumb rest above the neck pickup.
** NOT ALL RICKENBACKERS ARE EQUAL! ** The pick guard shape has varied over models, years and days of the week so the upper curve of the thumbrest may not match your Ric exactly but as long as your mounting holes are 84mm apart, centre to centre, the ThumbChum® will provide a convenient place to hang your thumb.
Great quality, made in the UK and around half the price of other thumb rests!
The kit is supplied with the two screws needed to fit directly onto your Rickenbacker without the need to drill any holes. Mounting holes are 84mm centre to centre. Fitment to non-Rickenbacker models may require holes to be drilled or the pickup cavity to be enlarged.
