I've had stacked volume on my L2000 for years, and on my old L2500 before that. I love different blends of the pickups on that bass and consider it vital for the sounds I prefer on it. I used 500K stacked pots for volume and a 500K on the Treble to help bring back a little lost treble from adding the extra Volume control. My "OMG" is also a push/pull selection via the Treble control- it changes the Series mode on the switch into OMG when pulled out. I also have seperate coil switches for each pickup, mostly so I can blend OMG on one pickup with Single Coil from the other. The way OMG works, as long as you switch the orientation of the coils from one of the pickups when you wire your switches it is hum-cancelling with both pickups on and partially hum-cancelling when blended with single coil from the other pickup.
