Do folk upgrade to 500K for Trilogies? Interesting, I wouldn't have thought of that, I just assumed they were still "strat singles", so still 250K, but it sounds like you've done it Antag...
Having said that, I only go as hot as Irish Tours... :lol:
On the baseplates, I haven't heard them "in the flesh" on strat coils, but I do know what a difference they make to tele bridge pickups. It's like more "meat" - the pickup kinda sounds the same, but like Antag says it seems a bit more powerful and has more low end punch to it.
On a tele bridge, I like that. On a strat I'm personally not so sure. When I got my ITs, I decided not to get a base-plate (bridge was the only place I considered it), and I'm really glad I didn't, my IT bridge already has a nice punch to it - it's the first strat bridge I felt comfortable using on its own. For me, I think that more punch on that pickup would have been too much.
Did you tell Tim what kind of music and everything?? From watching other people's posts and his recommendations, I suspect that he would have mentioned/recommended baseplates if he thought you needed them. You could still ask, I'm sure he won't mind :D
And another welcome from me! :D
