Thanks everyone for your input ... much appreciated. bsee, sorry to not reply earlier, I've been too busy to even plug it in. The bass sounds great. I already knew which switch belongs to which pickup, I just never knew until now what they are, as in filter or boost ... thanks for clarifying that for me.
I haven't heard yet from Mica, but it does seem like it's got signature electronics. I really love everything about this bass, especially how it sings, and am going to hate letting it go -- it just doesn't get much playtime these days. Ironically, just as I decided to go through with listing it for sale I got offered an electric bass gig.
