You know enough to ask the question :-) (that's a whole lot more than the average person)
Thanx Edward for the great explanation! Agreed completely.
When I was in a more traditional band with more traditional fretless sounds, I found the bass control extremely useful.
From a previous post: I find the bass and treble control very useful for fretless, when soloing the bridge pickup you can add lots of bottom while retaining that awesome "mwwhaaa" tone.
With the filter further tone shaping is a bit more intuitive for me, great combination!
The bass control is very powerful, hence the crackle in the sound with the louder parts. (overdriven interface, you can see it going red below my left arm)
Got to work on my Bob Rock skills :-)
I'm pretty sure the Treble control is stuck in the center dent position, more than enough highs for me in these basses.
When I was deciding on my custom basses, I also considered getting a fretted and fretless Spoiler 5. (instead of the Newsted set)
For the fretless I would have added the bass control for the bridge pickup only, combined with Series II electronics. (more than enough lows for me on the neck pickup)
I don't remember if that inquiry made it to Susan's desk, but will definitely ask for it if the opportunity arises again some day. Still dreamin' about those Spoilers
With the fretted basses I don't miss the controls at all, as Edward said: "it's all there"
