More umph from my jazz

[Doug4321]

I don't get the question in a way. You have two basses, one has much louder/hotter output so of course it has more "oomph".

A lot of amps have a button that cuts the input for active basses, something like -10db. Leave it out for passive basses.

You'll have to adjust the volume and probably eq to get them in the same ballpark when switching back and forth.

I have two passive basses, one with much hotter pickups, so a similar issue. Volume on 10 on the jazz is like master volume on 7 on the Guild (leaving the amp volume the same).

Here's my two part, affordable* way to make a J more oomphy. Either of these options work great, and I usually find it's best to do both.

*assuming you are hands on with wiring. Adding tech labor will double or triple the investment.

1. Install a push/pull pot to do series/parallel wiring. Series adds beef and output, but does compromise treble.
2. Install this Duncan preamp in place of your tone control. Now you can boost and cut bass and treble to your heart's content. Blackouts® Bass Preamp

Also, in defense of the low output jazz, this may be advantageous in some ways. Cleaner, balanced output, more headroom kind of thing.

I just got a sterling stingray 34 and I get a bunch of low end from it but it is still slapable which I love. I love the feel of and look of my old mim Jazz. What can I do to get the same amount of low end from it? Any tips, mods, etc?

If you want to make a tonal difference on the cheap, you could switch out the tone cap with a 1K. Worked for my Fender PJ.

How about this - instead of trying to get the Jazz to sound like the Stingray, can you get the Stingray to sound like the Jazz?

So set the amp to sound good with the Jazz, then cut stuff on the Stingray to match?

(I know this probably isn't what you want to do - actually not sure of the ultimate goal - is this to balance the sound for live use? Or you just like the sound of the Stingray and find the Jazz lacking?)

Again, series. I do that plus I use SD Quarter Pounders (no, cheese).

I'm not going to slog through all the posts, so please forgive me if someone's already mentioned this, but if you have your pickups wired in series and your tone pot replaced with a push/pull one so you can switch back and forth between series and parallel as you wish, I can virtually guarantee you'll get the results you're looking for (and that you'll probably never play it in parallel again).

My $0.02 is:
if the sound isn't there in the guitar it isn't there. Use the guitar that has the sound that works for the particular band. You can have a jazz that sounds more mid rangey and you can have one that's got a ton of low end. For me the quality of the wood is the place to seek changes. The pickup just transmits what your hands can get out of the wood.
