Finally got to the practice space. Mules set in a PRS Singlecut Korina, straight into a Rockitt Retro 50, which is a clone of the builder's fave 68 50 watt Plexi. I have the optional PPIMV. Ran it into a Marshall 1960 4x12 that the studio has. I think the speakers are the 75s? I'm more of a Greenback guy, but this cab works decently well.
Volume was loud, probably louder than some gigs these days, but I didn't have the amp dimed.
Bridge Pickup:
Playing crunchy, the chords sounded balance in terms of frequency, no particular frequency was too much. Classic crunch, although that's a description that could mean different things...
Leads: Initially, it seemed a bit bright, probably because most humbuckers I've used for gigging hve been hot, various Duncan and Dimarzio offerings like the Invader, Super Distortion, and X2N. Currently, I have a Crawler in a Strat.
After playing the leads a bit, I really got to like the cut the brightness gave it, and I also realized that a number of artists I like have that brightness to their playing. I think it was just a matter of my ear working with the sound.
Neck Pickup:
Talk about blues rock heaven! I generally stay off neck pickups, but I see this one getting a lot of use. Just a cool warm cut, if that makes sense.
It occurred to me that the overall sound of the Mules in the PRS, going straight into the Marshall clone has a somewhat similar sound that the Stones might have had if they'd used Marshall half or full stacks on Get Your YaYas Out.
By the way, I have used lower output humbuckers before, but it was a long time ago. What I do remember was that the bridge pickups were bright in a cheap way, and the neck pickups were just plain mud. Certainly not my experience here.
I also did some clean playing, and they would be fantastic for funk, or blues, or any rock style that requires clean sound, IMHO.
As always, YMMV, but I am happy.
Edit: As I listen to Savoy Brown's Blue Matter, I'm thinking that the soloing is right down the tone alley of these Mules, especially on It Hurts Me Too. I know that there are different ways to get there, but the Mules are doing it for me.
