Rewiring for Blend/Master Volume

[zulujack]

I'm not electronics wiz but I recently got a Specter with 2 volume controls neck/bridge pickup volume and I'm finding it very impractical as all my other basses have a master volume and blend knob. It has the following layout: Bass boost/treble stacked, mid, bridge PU volume, neck PU volume. I want to rewire it so its: Bass boost/treble stacked, blend, master volume. Can this be done fairly easily? Are there any wiring diagrams I could look at? Any help would be appreciated.

The easy way is to buy an Audere preamp module (3ZB2-VB). It has this feature. Otherwise start with the schematic diagram for your Specter.

I'm happy with the EMG preamp on the Specter. Just thought maybe its an easy swap.

EMG has a good wiring schematic site.

Here's a schematic of a preamp that has the blend/vol arrangement of pots. It really depends on whether or not each of your pickups is individually buffered or whether they each drive the wiper of the corresponding volume pot before driving the preamp.
