Hey Guys At my church, we are holding a large music conference, being put together by our music pastors Doug and Laurie. Doug plays bass(an Ibanez SGR405, to be exact) and he let me know that he would like me to "prep" his bass, as he will be far to busy to even check if the thing is in tune, much less how the preamp is set and how it looks. So, I need to know what I should do to "prep" the bass. He said whatever I can do, I should. But be sides doing a quick soundcheck, putting it in tune, and polishing it, I don't know what else to do. Perhaps someone can give me an idea. That would be really great. Also, does the 405 have active electronics? If it does, I'll put in new batteries. Thanks for your help.
