Left, BB1024x (standard P).
Right, BB424x (reverse P)
Couldn't compare the two due to different pickups, strings and bridge, but the 424's G string definitely sounded more meaty after the conversion. I quite often feel a P bass's G string sounds a little thin (it's probably just me) and I definitely think a reverse P sorts this out (for me).
The 1024 has gone, I still have the 424.
