Spector Euro 4 EMGs with a passive switch????

Discussion in 'Basses [BG]' started by Theexploitbass, Feb 28, 2005.

  1. Ive got a Euro 4 Spector with active EMGs, I love the sound tis rather beautiful, but ive also come to love the sound of a passive bass. Just seems a bit more agressive, and the active just have shed loads of power!!

    Is it possible to put a passive switch on my bass, pickups are EMG-PJ??? How does everyone feel about modifying a bass of this stature, im unsure whether to do it or not??

    Any help would be nice!!

    I think it's a good idea. I would look into a push/pull volume pot that switches from active to passive rather than drilling another hole.
  3. Hmm... I'm far from being an electronics specialist, but I don't think EMG's can be used with a passive circuit. Active pickups have very low output and simply need to be boosted by a preamp.

    The EMG's are an active pick up but you can have a preamp bypass that will defeat the onboard pre in your Spector (EMG, Aguilar, TOne Pump, etc) but the battery will stll have to power the EMG pickups.
  5. I'm not completely sure the output is lower on active p/ups but the magnetism certainly is, with the mini amp compensating for the difference. EMGs own wiring documents for the active PJs show no active pre-amp.


    I would say that cutting out the active pre won't necessarily give you the passive sound you're looking for as the p/ups are still quite different from most passive setups. But you will get some sort of different sound. Check out the Aguilar site (common on US spectors) which shows how to wire a by-pass.


    +1 on the push-pull volume knob.

    I'd love to know how you get on as I want to out this option "Spector sound-alike" custom.

    Maybe an option is to go with EMG P-HZs and J-HZs, keep the active tone circuit, and install a bypass switch. Not what I'd want to do myself, but that may accomplish what you're looking for, at least partially...

    Those pickups are Active only. You can't run them passive. You could put in passive pickups (EMG-HZ's) and an active pre with a push-pull bybass.

    Oh yeah, what RexGroove said......

    I personally have no problem modifying these basses, everyone of mine has modified electronics and I've made mods for other people. I've actually even provided my alternative vol/blend wiring diagram to Spector for one of their customers.

    If you don't want to drill a new hole for the switch and not have a push-pull vol pot you could stack the 25K tone pots. That part is easily found, I have one for a project I'm working on. I think it was $30. Kinda pricey, but it does the trick.

    I also think that this will not give you the sound you want. Spector's are designed for Active electronics. The solid brass bridge, solid maple body, thick neck, brass nut, these all go together to give it that signature Spector tone. You're not going to get a passive P-bass tone out of one of these no matter what you do.
  8. Cheers for the Help you guys!! Taking into account what you said, im gonna leave the Spector how it is, such a beautiful bass i dont want to mess with it...

    so im just gonna save up and get another bass :)
