Sounds like an interesting project Nightman and a lot of fun too. I'm doing the same thing right now as I finish the basses I'm working on. Every bass has the same pickups & circuitry and all setup to the same specs with the same strings through the same amp with the same settings. So what I'm hearing are the differences in the wood combinations. You said two things that I've heard before from players who have played my basses and I find it interesting that you use the same words they did, piano like tone and tight string feel. I had one guy come to my shop on a quest to find a 5 string without a floppy feeling 5th string and he commented on the tight string feel. Thank you for posting your feelings on the results of your test.
