I have a montana era gibson F-5 that I really like but the finish on it is a little heavy looking,Im taking it down to Gibson the 30th of this month. Big Joe said though they cannot make guarantees the ones they have done come back with better tone and volume. Just would like some comments again on this procedure by players or otherwise who have done this and if they liked the results. Im hoping although it sounds good now it will let it ring more? I know they will do a good job and I am excited about the possible results. Mark
