I just picked up a new Andreas Eastman fully carved bass, model 605 since im going to ithaca college next year. I have just a few questions of the upkeep of it. I know to wipe the rosin off of it after im done playing and all of the basics, but one question in particular; what should i use on the finish to keep it as shiny and great as it is now? Also, any suggestions for humidifiers????
