So I had a set of these so-called Dyna-lite DeArmond 2000 pickups laying around, so I thought I'd try them in my Duo jet. Remember I swapped the pots for 1meg some time ago, as I found the T-Armonds too mid focused, hoping some more top end might balance things out. To be honest, they were OK, but not really snappy enough so, out with the T-Armonds, and in with the DeArmonds. They are a straight swap using the TV Jones compression rubber mounts, but note that Gretsch Dynasonic spacers don't fit the DeArmonds. I really like them. Very much like regular Gretsch Dynasonics, with a slight scoop in the mids. I think the 1 meg pots really help, and anyone with a 512x series could likely benefit from swapping the pots if they were looking for a bit more punch. Just gotta figure out what to do with these spare T-Armonds now! I might send them off for a rewind to drop a few turns off the winding. Dunno yet.
