I have three strats with the following pickups: -- Van Zandt blues (staggered) -- Suhr 60 LP's (staggered) -- Rio Grande Vintage Tallboys (flat) I also have a new amp, a Goodsell 33, and it's like a "truth machine" for guitars. If you have a string rattling or fretting out, you're going to hear it through this amp. With the staggered-magnet pickups, there is a noticable sonic "hole" where the B string should be, and to a lesser extent the high E. Those strings sound weak and anemic compared to the rest. With the flat-magnet guitar, I get much better response across all the strings. It's really, really noticable. The funny thing is I've had lots of good amps, but none that were this sensitive to the string-to-string variations from staggered magnets. In fact, I've never noticed a difference between a guitar with staggered or flat magnets before now. I really like the amp, so I guess I've got choices. I could obviously seek out flat-magnet pickups for the other two guitars. Could I also manually adjust the magnets on the other guitars? I know the magnets will slide up and down some, but they're also different lengths and I don't want to risk wrecking a pickup. Perhaps I could send the pickups back to their respective makers to have the magnets swapped out for ones that are all the same length. Any other suggestions would be appreciated.
