Who makes the best onboard preamp?

allenhumble · #1 09-22-2006, 07:45 AM

I have seen a lot of good reviews on alot of different products and have read the Jretro vs. Audere comparison. However there are other companies such as Demeter and Sadowsky that also have made available preamps for purchase. Does anyone have expeirience with one or more of the products that can give there opinion? Or are there any other products out there that should be considered? The pre amp is to be paired with Nordstrand dual coils. Thanks

Well, I have Aguilar OBP pre-amps in two of my basses. They both sounded amazing after the upgrade. Good luck with your choice...

I've used pretty much every preamp out there - Bartolini, Aguilar, Sadowsky, J-Retro, Audere. Not demeter though. They all have their pros/cons.

I can give you some advice if you give me some more requirements.

What are you looking for? 2 band/3 band/4 band?
Boost only? Cut/boost?
Stacked knobs/single knobs?
Active/passive bypass?

just to make it clear, you are talking about a Jazz Bass type bass ?

also, please write down what you are looking for (3 band EQ, what vol. configuration for the pickups etc.) and what's your budget.

im saving for a preamp as well so the answers will help me a lot, after digging inside this forum and FAQ im in the direction of the OBP or the JRetro for my Jbass.

I am looking to replace the pickups and electronics in a Lakland 55-01. It has a Bartolini MK1 which is a 3 band. Five wholes in the body so I don't think I will need stacked knobs, but I am not opposed to it. Boost/cut and active/passive bypass.

i've had the jretro in a j-style bass,it was really good for reasonable bass/treble-selectable mid type boost----- however,the demeter is a more natural sounding(not as hyped)b/t and mid point selectable pre. jim put these in basses of mine out of his garage in the mid 80's in L.A. it saved a peavey tl5-enough said?

If you want an active/passive bypass where you can still use the blend knob in passive mode, then choose from any of Aguilar OBP-3, Demeter, Bartolini. Like I said, I haven't tried Demeter but have heard good things about it. Out of the other two, I personally prefer the Aguilar - it's more transparent to my ears than the Bartolini.
Bartolini does have something that can be useful, adjustable preamp input gain - useful with many bart pickups which can be quieter than other brands. Demeter/Aguilar preamps are unity gain, that is the sound with preamp engaged and eq flat is same volume as with preamp in bypass mode.
On the convenience side, you can buy the bart preamps prewired in the knob configuration of your choice. If you buy from Brian at http://www.bestbassgear.com, you can get your factory-wired Bart preamp or Brian will wire you up an Aguilar in whatever configuration you want.

Audere audio make the quietest onboard preamp I've ever heard. Unfortunately, they don't have active/passive bypass on a push/pull switch so you'd have to drill another hole in the bass.

Hi David,

im looking for a preamp that will boost the mid like in the NTMB that i have in my pedulla,
the OBP3 will do it ?
also from your experience did you had to make routing in order to fit the preamp into a fender jazz bass ?

thanks.

You're going to have a tough time getting an obp-3 into a jazz cavity without routing. I'd check out the Audere jazz bass replacement preamp at http://www.audereaudio.com, there's also the J-Retro drop in. But IME the Audere is infinitely quieter than the J-Retro

+1 on the audere

I plan on getting Nordstrands dual coils in a future bass and I'm getting the Demeter. I'm choosing the Demeter because I've heard that the Dual Coil pickups sound amazing with very little EQ, the less the better...

I've had years of experience with James Demeter electronics...nothing I've heard sounds as natural or as useable as the Demeter.
