I have the single element one, I knew that the two element would be way too bright. Just for clarity, when I say ‘bright’ what I mean is forward, edgy upper mids.
In terms of impedance, I’m going into a 10 megohm input on a Clarus.
I’ve now used 5 different pickups in the past 2 years; underwood, lifeline, realist copper, full circle, and Yamahiko. I’m going to keep the Yamahiko on for a few gigs and see how it works, but here’s how I would ‘rank’ the pickups from most upper-middy to least: Underwood, Yamahiko, full circle, lifeline, realist.
The realist and lifeline are both too muddy for my tastes. The underwood is very harsh on the upper mids. The full circle and the Yamahiko are in the middle, and I need to spend more time with the Yamahiko. It does seem to have a better low end than the full circle. It’s very high output. I’ll play with it for a while.
