V4lve Posted August 16, 2009 Posted August 16, 2009 (edited) Hi. Using my newly acquired OLP MM3 in public for the first time this morning and found that it was difficult to mute the bass while I am not playing without messing with the volume at the amp. Problem is that I am used to using the volume control on my bass as a mute between songs. I run my bass flat out and control tone at the amp. The MM3 has separate volume controls for each coil and unless I turn them down together at the same rate one of them picks up the induction loop and produces feedback. The simple fix is to mute using the amp volume, but this is problematic as it is easy to get wrong when I need the level back up. Is there a simple fix to turn the MM3 controls into a volume and blend control? I know I can probably do this by going active but I would prefer to stay passive. Thanks for listening.

BOD2 Posted August 16, 2009 Posted August 16, 2009 You'll lose the separate control of the two coils in the pickup but this diagram will give you a master volume and master tone...

I was having a poke around this site last night. Couldn't find a blend option... Is there something in the jazz diagrams I could use? Quote
BOD2 Posted August 17, 2009 Posted August 17, 2009 I suppose if you have a look at this [url="http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=jazz_bass_blend"]http://www.seymourduncan.com/support/wirin...jazz_bass_blend[/url] and cross reference it with the other MM diagrams and the colour coding on your own pickup, then you might be able to do something. Search this site for "Blend Pots" as well, as there seems to be issues with some blend pots not doing what they should. Quote
robert43 Posted August 18, 2009 Posted August 18, 2009 The olny new pot you need is the blend pot. The 2 OLP white leads go to the centre leg of the blend pot & blacks to earth, as it is showned in the SD web site. Quote

I think I prefer the the blend solution as it doesnt require me to change my habit of turning down the front volume. ta Quote

I have worked out how to wire this in but unfortunately it seems the nut required for this pot is larger than the one it is replacing. Really dumb question but...any idea where I could get one from? Are they standard sizes? Edited August 25, 2009 by V4lve Quote

NickH Posted August 26, 2009 Posted August 26, 2009 (edited) As posted above, you could use a mute switch to kill the sound between songs. If you're not keen on changing the look of your bass, you could use a push/pull pot (about a fiver on eBay) in place of one of your existing regular pots. If you go for this, or if you use a regular toggle switch in place of the push-pull, remember to connect the output part of your signal path to the centre tag on the switch. Put the incoming signal on one of the side tags and earth the other. That way your amp is either connected to your bass' signal or it's earthed and silent. If you do it the other way, by putting the incoming signal on the centre tag and the outgoing line to a side tag, when the switch is in the "mute" position your amp's input is basically hanging and will hum like a bitch - the same as leaving a jack lead plugged in and the volume up but no bass connected. *** NINJA EDIT *** OK, my first post had painstakingly drawn-out ASCII art circuit diagrams, which when posted resembled nothing so much as a monkey spamming the O-_I keys while on acid! PM me for wiring diagrams etc. Edited August 26, 2009 by NickH Quote
BassBunny Posted August 26, 2009 Posted August 26, 2009 You need to make sure the blend control has the same values as your existing Vol controls. Eg, if the existing vols are 250K, you need a 250K blend. If the values are not marked on the Vol pots, I would go with the push/pull solution, but again the value needs to be correct.. Quote
