In, just to say I miss QVC... I haven't had cable television since 2007. Many a sleepless night those those endless infomercials kept me going though... somewhere deep, deep, deeeeep in the Acoustic Endeavors cataloge of tunes that died in the cutting room is cute a little mandolin instrumental piece called "Infomercial".
I add or take away Q-switch just based on taste. Like Jazzyvee, most music I play calls for warmer, mellower tones. And to that end, I had 3-position Q-switches with lower values installed in both of my 5-string Alembics. 0-3-6dB. (I think...) I tend to play with them either off, or in the middle position. On my Series bass, same... either off, or middle position. My other Series bass has been fitted with CVQ's, but I've yet to try them... the Elves are still exorcizing its gremlins. I kinda' expect I'll just adopt a 'set it and forget it' policy with them as well.
