I havent changed anything about my nearly unused pedalboard in a few years, but I might soon.
Lately Ive been running the stereo outs of my 4003 into separate channels of my Focusrite for headphone practice and have found that active mixing each pickup separately is much more useful than passive blending of the pickups which is already built into the bass. The volumes have a useful range, a variety of tones can be had from blending them in slightly different amounts, and having each pickup buffered before blending makes the blended tone more clear than just running both pickups with the mono output.
So based on this positive experimentation, I have been thinking about adding something like a Radial mix/blender to the board. This way I can have active pickup mixing functionality on the board as it has high impedance inputs, and I can route the pickups separately through dirt or comp if I wanted.
Thoughts, comments, concerns?
