Question: EBMM Axis – replacing volume knob with push/pull for spit coils

When it came in I found that the both position 1 and 2 on the toggle give me both humbuckers and I’m unable to get just the bridge humbucker alone. Position 3 give me just the neck so thats wired properly.

I’m going to get the toggle rewired and was thinking it might be worth replacing the volume knob with a push/pull knob so I can split my coils and get the single coil sound for more versatility. How has that worked for folks in the past, do these DiMarzios work well in single coil split? Am I sacrificing a high quality volume knob thats currently on there for a cheaper push pull simply for more function? Is there a potential downside to doing this that I’m not aware of?

I love the idea of more versatility but don’t want to do any “damage” to what I have. again, I waited 20 years so I’m super happy to have it but i was disappointed with the pickup toggle situation.

Thanks!
