How much (if any) does the "PJ in 2 EMG soapbars" tone of 5-string NS2s differ from the 4 string ones in conventional shapes?TBer @AgingEngineer makes a very highly regarded Haz clone (LHZpreamps.com) and a pedal version of it called HAZLamps. Combined with EMG reverse P and J (even the soapbar versions for 5 strings) in the right locations, it's easy to nail the sound.
For instance, Bartolini P soapbars are around 32 mm tall, too narrow to accomodate the squat split P in a single housing and I guess their split soapbars are more akin to a split J bobbin than a true P pickup. EMGs are taller, but I don't think you can fully fit a split P in there. How much that can be controlled by other parameters tone-wise I actually don't know. What's more, even two identically shaped pickups can sound rather different, so there you go...
