make pickup active

Re: make pickup active

They do have modular preamps (duncan), but I'm not sure how well they work with various pickup models.

You can't MAKE the PRails active, but you can add active electronics to the wiring harness.
 
Re: make pickup active

Onboard pre-amp designed to accept a "passive" pickup. I use a Duncan one for bass. I would assume they make a few guitar ones too (though I'm not sure).
 
Re: make pickup active

I don't know why you would want to do that but you can install an emg pa2 for example. If you use a passive pickup with the emg pa2, you can also use it together with active pickups(middle postion on a 3 way switch) and you will not have a volume drop when you switch between pickups (if you set the gain setting right on the pa2). You could also try a seymour duncan blackout preamp, but I'm not sure if you will be able to use it together with full active pickups..
 
Re: make pickup active

An on board pre-amp and passive pickups makes it hard to get predictable results. It seems too much money to spend when its really uncertain what tones you will end up with.
The big issue is the effect of the pickup resonance (Q factor / frequency), and how its going to change when you move to an active preamp.

If you want active pickups, its much better to choose an active pickup in the first place. EMG makes the 89 and 89R split-able humbuckers which are noiseless when in single coil mode, so maybe consider those if you want to go for actives.
 
Re: make pickup active

There's precedent; early Musicman and G&L guitars used 'passive' pickups with an active preamp. You would probably want to use darker pickups with low value pots...
 
Re: make pickup active

Also the earlier Jacksons did it with that built-in mid-boost. My old 91 RRproffesional had it.
 
Re: make pickup active

Many basses have passive pickups with an active boost. You certainly could add something like a Blackouts preamp to the P-Rail. I haven't done this, but it sounds pretty interesting.

I have a funny story related to that.

I got a G&L L-2000 bass in 1996. As you may or may not know, the L-2000 has two humbuckers, active electronics, and a bunch of mini toggle switches. But at the time, I didn't know all that. I just brought it home, flipped a bunch of switches until it sounded good, and I haven't touched the switches since.

A few years ago, I got curious and looked up what all those switches actually did. Turns out I had been playing it on the neck pickup only, in passive mode, with series coils all those years (literally decades, actually). And all that time I thought I was playing an active bass! I might as well have been playing a Precision all those years, with the way I had been running it.

Not 100% sure about the MM StingRay, but my Sabre II's pickups are LOW impedance and use 1/4" slug mags, with a buffered low-noise preamp. I love these guitars.

Re: make pickup active

The 'metal plate' CLF reissue L2K basses are very appealing to me (still including active circuitry.)

Googling what the Musicman switches do is apparently rough- I was basing my understanding on a distant recollection that at least some early Stingrays were pure passive/conventional setup, while using the same pickups as the active models. That would put them in the same league as the F100 , with a switchable pre-amp and the same high impedance pickups used on non-active models (granted, I figured the Sabre was the same way.)
 
Re: make pickup active

EMG stuff to add (to passives and to actives) has really gone gotten crazy with the prices, partly due to going all quick-connect I'm sure (well that's their story lol).
I've always wanted to try-out some of their add-ons but they're basically the price of a pickup now!
 
Re: make pickup active

Modular preamp

OR wire it in series, thru an EMG (hijacking its preamp)

Theres some trickery involved with pot values to separate them and the two pups cant share common ground for to work right


Known to work with preamps inside:
EMG 81
Duncan APB2
