It's easier when the filter already has a switch, just remove the two wires from the filter board and replace with the new one.
Does require some soldering skills...
Hey FC Bass, so if Keith_H and I want to change the 2 Q switches (2 position) in our SC Browns, we just need to swap the current 2 position Q switches with 3 position switches and desolder - solder 2 wires for each switch to their respective filter boards ??
In which case Keith_H this is an easy mod for you and I, and we gain more and loose nothing (my understanding).
I agree with FC Bass re master vol if you went with Anniversary electronics, I like the individual PU vol controls but a master would be a nice addition.
So I tested the "stereo" option the other day, it's not really stereo, what it is is one PU routed to each channel So using stereo (T/R/S) jack, Tip = Bass/neck PU, Ring = Bridge PU. So I made a lead stereo jack to 2 mono jacks, plugged into 2 preamps > desk > stereo amp > 2 cabs (I also used desk to studio monitors). Sounds very nice and opens up a raft of panning and patch possibilities (this is a place you could loose yourself for a while LoL). Probably more useful recording than live unless you want very different sounds on each PU ? Then also depends on your preamps (I used 2 ADA MB1 preamps), I was running a SS patch on the Bass PU and a tube patch on the Bridge PU. Now this is where a master vol would be a very useful addition (I was wishing I had one, well I kind of did using the MIDI CC pedal master volume control on the MB1s)
