I’ve never owned a Muckelroy “yet” or any bass that didn’t have a painted finish. One question that I’ve been wondering, what types of oil (oils, mixture etc) do you use for sealing your basses and how many coats or applications do you apply to each one, and does different wood types require less or more? And does an owner of one of your basses need to periodically reapply?

I use a three part mixture of teak oil, thinner and semi gloss poly. I use between 3 and 6 coats depending on the woods involved. Woods that are less dense or more open-pored tend to drink up a little more, requiring more coats.
Owners of instruments with this type of finish do not need to reapply this oil. For maintenance and cleaning, I recommend a product called Howard Feed & Wax. It’s great on the body, neck and fingerboard…..especially the fingerboard. Howard Feed & Wax can be applied either every 6 months or during string changes. You simply apply a small amount to a soft dry cloth, wipe it on, let it sit for a few minutes and wipe off the excess with another soft dry cloth.
