I have three Sterling JP70s, all of which have different pick ups. One has the LiquiFire/CrunchLab combo, another one has the AirNorton/ToneZone combo and one has the stock PUs.
I just recorded a very short riff, to compare the three (only the bridge PUs were used on this).
To be honest I don't know if I hear a difference at all - am I tone-deaf or what?!
If you guys can tell a difference, let me know which version you tihnk sounds best, or if you think you can tell, say which is which PU (CrunchLab, ToneZone or sterling stock PU)
this is version A:
Well, I liked B best, but I think it's because of it's more palm muted. I like C next, then A.
So my guess is A is stock, B is Crunchlab, C is Tone Zone.
