Hi All, I can't find any satisfactory info on this so thought I'd bring it to the forums. My unamplified arco tone sounds much, much better with my Underwood pickup installed. I took it off as I'm only going to be playing orchestral stuff in the near future and the tone changed enormously. It's like someone cranked the mids on my tone (which sounds awful to my ear compared to having it installed). I do the odd concert with a community orchestra every now and then and I've always removed my pickup (at least for the concert) and I don't remember ever noticing this before. I can't find any info online about this effect or how others deal with it. No one seems to be talking about jamming shims in their wing slots which is what I'm tempted to do as it'll be a little more discrete than having the pickup wire hanging out. So I'm a bit baffled and wondering if this is something that others have come across? Thanks!
