Well I've had the new pups fitted about a week now and all I can say is wow! What a difference. The guitar didn't sound bad at all before and it was a hard decision to mess with my favourite guitar, but I'm glad I did. The pups have really opened up the guitar, the mule in the neck is similar sounding to the prs stock but has so much more clarity, punch and dynamics. Also has a much more vocal/expressive quality. The riff raff in the bridge has less output than the stock prs #6 but this really opens things up, the bass is much tighter and the pup has a lot more edge to it, just the right amount of edge and this really balances out the guitar. The balance between the two pups is also much better, and the tapped sounds are much better too. The biggest difference I have noticed is how well these pups clean up on the volume pot. Also how they handle hi gain without the loss of dynamics like the prs pups.
The amps I have are the Marshall sl5 combo and a Marshall jvm half stack. The biggest improvement is on the jvm, as the hi gain sounds are now much better. I also installed a bkp jenson .022 cap in the guitar so I'm sure this has helped with the improvements.
Only trouble is i now want to upgrade the pups in all my guitars!!
