I'm so used to working the tone knob on all my other basses. It's second nature to me, and I think a tone knob would be a handy addition. Added flexibility that you can't get from an active preamp.
I have a LPF already.
But you're not wrong.
Ah.
I was going to go with a passive tone control on my LG 5 PJ- but with the configuration I wanted they'd have to drill another hole for an active passive switch- and Keith wasn't too keen on the idea as he's had tough luck with drilling spalt after the fact, or I'd have to give up the mid controls and from the 3 band to the 2 band Bart preamp.
In the end, mid controls won out for me, so I kept the active/passive option with a push/pull volume knob and the 3 band EQ. I'm glad I did as I really like the mid freq control on the bart 3 band. I figure if I miss the tone control I'll add the LPF to my small collection of pedals.
