Mid/Treble cut/boost stack suggestion
 

I'm planning on adding a mid/treble cut and boost stacked knob where my tone would sit on my fretless Jazz. ..... The bass isn't stock and has extremely over wound old Jazz pickups so I'm just looking for sparkle. .... Anyone suggested a make that might do that? 9V is fine.

Just about any three-band preamp will do that. But why not have the bass control, too?

Like I said the pickups are really overwound, half again more than a standard Jazz pickup, so what suffers is the treble. And the reason I removed the passive tone control, I wasn't ever going to remove the top end and it gets in the way of a good signal. ...... I'm thinking I'll get more use from a mid/treble combo. .... Just fishing for brands that offer that already.
