pickles said:The other way to go is to get an amp that has less high end response, or turn down the highs at the amp.
+1... however, then you lose the ability to 'go the other way' and dial it back in. Also, +1 on the amp treble, but an active treble cut on an amp is a very different animal than the nice, smooth passive treble roll-off of the VTC.
As you point out though, if you have a more 'traditional amp' and cab that does not really reproduce high treble, then it's a moot point. However, for more 'modern sounding cabs like Epi, Berg, EA, Eden, etc.... the VTC is a really nice thing to have on those basses... especially on the maple/ash models.
To put this in context, I'm a fan of Marcus Miller type Jazz tones. While the Sadowsky Vintage is not the best bass for that tone, I have never used the treble boost at all... to give you an idea of how bright these basses are. With just a little bass boost and the VTC all the way open, you have plenty of treble for a nice slap sound.... however, those basses are just too bright when flat even for me.... the sizzle lover! I think part of it is that the treble response of the pickups and preamps set 'flat' is in the lower treble area than basses like the MTD and Celinder, for example. It can really get 'harsh sounding' unless rolled back a little IMO.
