Hello again, y'all... and thanks again for all the great replies/suggestions/comments.
A 0-6-9 dB 3-position Q-switch for my Orion is on the way ;-)
After playing around with the current 8dB filter, and seeing as the Orions are set-neck / mahogany-bodied and a little darker/less 'snappy' than my bolt-on and neck-through basses, I felt going to 'off/a little below/a little above' where it's currently at was a good option for me. We'll see how it goes on the fretted and maybe do the same for the fretless if I dig it.... Keep y'all posted and have a great holiday!
