Twincam Posted April 26, 2016 Share Posted April 26, 2016 I really don't use my john east pre as in passive it sounds the same as the flat eq. And it has a passive tone control which I use. I tend to use the amp eq for adjustments. I think the nordstrand big singles sound nice passive. I also find the pre injects a slight amount of noise. My thoughts are remove the pre and go Vol, tone, tone, blend. Right now it's vol/blend, treble/bass, mid/sweep, passive tone. And two switches active passive and a mute switch. I'm concerned about the impact on the value of the bass and it will leave a redundant 18v battery box on the back. Also the passive, active switch would need to be maybe a pickup selector might be useful though, set the blend then have access to three different tones via the switch. Thoughts?

hubrad Posted April 26, 2016 Share Posted April 26, 2016 I took the East pre out of my Overwater J5 - bought used - and frankly don't think about the impact on value. I already knew that bass is a very long term keeper! If you're likely to shift the bass on in a while, but don't enjoy the pre, take it out but keep it on one side for selling day. If the bass is a keeper, sell the pre and buy a few sets of strings! ;-) Quote Link to comment Share on other sites More sharing options...

gillento Posted April 26, 2016 Share Posted April 26, 2016 If you are worried about the value of the bass, I'd get a whole different passive harness and keep the original preamp wiring intact. This way you could easily wire it back to its original condition. This being said, I only play passive basses nowadays. Even a bass having a preamp sounds differently in passive bypass mode than when being strictly passive.... Quote Link to comment Share on other sites More sharing options...
Grangur Posted April 26, 2016 Share Posted April 26, 2016 I've come to the thinking that if Warwick made a passive P-bass style, that would be my ideal bass. So, I'm thinking of taking the pre out of my Streamer Stage 1 and fitting different pups. I'll be keeping the original parts though, so I can put them back when the time comes to sell..

BassBunny Posted April 26, 2016 Share Posted April 26, 2016 Here's a solution. If you use a passive blend, there is likely to be an overall volume drop as you blend one way or another. Noll make an active Blend which gets rid of this issue and actually has 2 small driver amps in each part of the circuit so you can set each pickup gain seperately. Called the "Mixpot" http://noll-electronic.de/guitar-electronics/mixpot/ This would, IMHO, be a perfect answer and the battery boxes would be used. The switches could be whatever you like, even DFA's. I wired a passive blend once and I didn't like it. Quote Link to comment Share on other sites More sharing options...

The Noll is effectively the same design of blend control that John uses in all his products. Quote Link to comment Share on other sites More sharing options...
Twincam Posted April 26, 2016 Author Share Posted April 26, 2016 Decided to go for the modification. I have a question how much does a used East uni 02 4 knob pre amp go for? As I will probably get it sold. Quote Link to comment Share on other sites More sharing options...
Roland Rock Posted April 27, 2016 Share Posted April 27, 2016 I also have a bass with passive/active capability with an East P Retro type pre. I prefer the passive mode, so just use that. However, I will keep the active pre in there as it has a huge range of mid frequencies which just might get me out of a sticky spot on stage during a gig.

ambient Posted April 27, 2016 Share Posted April 27, 2016 Why not just leave it in, and not use it ? It's always there if you want it then. Quote Link to comment Share on other sites More sharing options...
NancyJohnson Posted April 28, 2016 Share Posted April 28, 2016 I had a MM Bongo 5HH a few years back. I think that if I could have somehow removed the active circuit and gone passive, I'd still have it today. Quote Link to comment Share on other sites More sharing options...

Unless the Pre is colouring the tone when bypassed? I've had a 2-band pre fitted in place of a 3-band on my bass so I can have a passive tone. I don't use the pre often as I find a proper tone control more flexible but I can boost treble/bass if needed - handy when gigging! Quote Link to comment Share on other sites More sharing options...

Dad3353 Posted April 28, 2016 Share Posted April 28, 2016 (edited) It's a shame that you can't come across someone hankering after an East pre-amp. Remove yours from your bass, the other bod fits it to his bass; win - win, no..? Hmm... Now, who would be wanting an East pre-amp, I wonder..? Maybe put it up for sale in the Marketplace here, and see if there are any offers..? Edited April 28, 2016 by Dad3353 Quote Link to comment Share on other sites More sharing options...

I've already offered it too Ambient. Quote Link to comment Share on other sites More sharing options...
Twincam Posted April 29, 2016 Author Share Posted April 29, 2016 Pre amp removed. Liking the new setup individual tones for the pickups plus the three way toggle and blend has given some extra scope for tone changes. I'm really not an active tone guy.

[/quote] How it's set up is you can set one pickup tone then the other different which gets a little different or you can set them and use the toggle to quickly go from deep bass motown to funk and inbetween quicker than messing about with the blend etc. Although after playing around the blend confuses the issue as it also effects the tone when using a single pu as well as working as a blend. Desperately need a new cab though. Even with a speaker upgrade this week it's pants. Quote Link to comment Share on other sites More sharing options...
