I have a Warwick Thumb bass - natural wood, bubinga body, wenge, ovankol and poss. one other for the neck. I am considering having a pro refinish (Both body and neck) into a solid colour. I have been told that due to the open grain of the Wenge, a polyester finish would be best. I have no experience on this one, and prior to committing serious funds on a pro quality job, would like to know if any of you guys have any experience as to if this type of refinish will alter the overall tone of the guitar at all, and if so, is there any way of knowing how? thanks for any help - regards, Webrax.
