I have two Strats, a 54 RI and a 62 RI. The 54 has the Duncan SSL5 in the bridge and I love it. It's not something I immediately think about until I've been called in to record and the SSL5 guitar often makes the cut. It's thicker, still stratty and full of rich harmonics. The 62 RI is a brighter and punchier guitar and has the Dimarzio Area 61 in it. I've really enjoyed this set for years not but I've found this guitar isn't my first choice for important sessions. It's a little thinner sounding, etc. I've wondered if I should put a Dimarzio Heavy Blues 2 or any silent SSL5 equivalent (as this is my hum-canceling guitar). The issue is to I go higher output or not? My fear is having two strats that sound essentially the same and losing the differences. The other side is that after years of comparison I favor the 54 Strat for the more important work by a mile due to the bridge pickup. Do I celebrate the differences or make a change?
