Im using an iRig into JamUp on my sons iPad to write riffs. You can buy different amp simulations and pedals. https://www.facebook.com/positivegrid

So as some of you guys know I have an old Brooklyn that is missing the original US 9V Preamp as well as the original Dimarzio pickups that the bass would have came with.
Right now it has EMGX pickups with VVTT controls, with two original switches that are not hooked up, and it sounds great, however I'd like to get it back to the original setup, or at least get an active preamp in there.
As we all know, the US 9V is hard to come by, as is the MM114 copy preamp. I was listening to limaguy's soundcloud comparison clips and to my surprise, I kind of liked the sound of the Tonepump and Aguilar OBP-2 more than the US 9V in the clips!
Now seeing as though the Tonepump and OBP-2 work with both active and passive pickups, I could install one of those with Dimarzio pickups and utilize the now useless switches that the bass has for their original functions (active/passive and phase).
Unlike a lot of guys, I used to run my old Spectors with the US 9v pretty much flat, with the occasional small boost of the low end. I'm one of the weird ones who aren't going for that growly aggressive Eddie Jackson/Rex Brown tone.
So what do you guys think? Would I be crazy to not go with the US 9V and EMGs? Would it be Blasphemy? Sacrilege?

hey guys , do any of you record with the iphone? if so what do you use? not looking for production stuff but just a way to get ideas down.
I actually use the voice recorder to get ideas down. It actually works better than you'd expect.

Big +1.

I put an ancient set of Dimarzio Model P-J's in my NS-2A and I love it, I can see why Stuart picked them in the original NS-2s. I think the Dimarzio's are a little less articulate but more warm and growly (IMO!) so I think its a good idea
Haven't used it in a Spector, but I have used Aguilar preamps and I like that they very subtly (if at all) color the tone, and are the most "true" to the pickups passive sound, so it could be a great combination, OBP-2 or 3 with the Dimarzios
Can the OBP-2 be made 18v the same the TonePump is with cable everyone uses here? Wasn't sure if it had to be wired differently for 18v.

Yup, should work the same. I did it with my OBP-3.
Yep. I used the wiring harness mod to bring the aggie up to 18v in my old Forte 4. It took all of about 15 seconds to do. And the sound was stellar.
Thanks guys. I may be trying this shortly.
Andrew........at 18 volts it's a different beast.....i think you will love it. I'm all about headroom and aggie's get it at 18 volts![]()
I think it'll be a much more honest representation of what that bass originally sounded like than what you currently have with the X pups.
I'd suggest the TP. It's a little grittier than the OBP-2. Unless you want a cleaner tone.
Add another 9v to the OBP-2 and it starts sounding an awful lot like the USA 18v.
Take pictures of the switch out and share!!! I'd love to see how everything turns out.
Also, go to Stu-Mac and invest in the copper foil for the cavity if you haven't already done that. It'll help with shielding the circuit from interference. Not really a big issue with JFET circuits. But still, if you go with passive DiMarzios it'll help.
