I ordered the Trilogy suite for the neck and Holydiver for the bridge (to replace the Nailbomb and Irish tour) while I was on a trip, and installed them.
The HD is absolutely awesome! Compared to the Nailbomb, it doesn't have that 'edge' on this guitar that had started to bother me. However, it's not a dark pickup, like I once mistakingly thought. The description on the pickup packet said something like 'vintage tone with contemporary power and edge' and that's exactly what I got. I can play something like 'Rainbow in the dark', with a powerful, aggressive, thick and articulate tone..and go straight to something like Led Zeppelin's 'Rock n' roll'. Mind you, it's not a copy of that Page tone, it just has that clang and twang I like when playing that sort of a riff. All without changing settings on the amp, just changing the way I attack the strings. It's open and very articulate, the guitar now sounds like I want it to sound!
I also had this little fear that the HD would make my guitar sound more like an LP, but no. It's still a Strat through and through. BKPs are sensitive to the guitar they're put into, and this is definitely another proof of that. It also cleans up nicely, I expected it to be more compressed.
About the TS neck pickup: compared to the IT, it's darker, thicker and higher output. Much more bottom. The IT had a very SRVish sound on this guitar, but the TS takes it a lot more in that Yngwie direction, and balances very nicely with the HD. I love it :) I said that it's darker, but it doesn't get muddy. At all. Just a powerful, thick and clear tone. Naturally, it's not as 'woody' as the 'custom 62' pickup set that I have in another strat, but that's a whole another world.
I'm happy 8)
