Sometime after buying my first-ever bass, I got some good advice from a guy working at a local music store. I mentioned a particular active bass I'd been considering for my first...a Squier Deluxe Jazz IV, I believe. He suggested I stick with with a passive bass for for starters. It was something to the effect of "learn to play first and get to know a bass' passive capabilities before diving into the complexities of active electronics". It may not apply to everyone, but I can see the wisdom of starting off simple, learning "the rules" through time and practice before advancing into deeper waters. That being said...

This right here! This basic truism will save you time, money and, as suggested before, will preserve your instrument's resale value should you decide to sell/trade it in. After all, a tone circuit's job is to roll off treble while preserving the lower frequencies, ja?Roll off the treble and you essentiallly have a tone control.
Speak for yourself, my friend!I would venture to say most people here don't still have their first bass - even one as nice as the one you bought.

Several Deluxe models, Mexican and American, as well as the Reggie Hamilton signature Jazz come to mind.
