Been a while since I updated this. Years ago I added an Epiphone Firebird VII, and I have another Vox amp, a small Yamaha amp, and a Pod X3 Live.
But the biggest change by far is the Sho-Bud LDG pedal steel that my wife bought for me as a complete surprise for my birthday last month.
Holy crap.
The shape of the tremolo plays a big part in the sound of Lemon too. I've always figured he was using a square shape, with reverb taking a little bit of the sharpness off of it:
Hearing Effects: Modulation 2 (tremolo, vibrato, pitch shift, wah-wah) | Easy Ear Training
I think the intro to Thunderstruck is well within Edge's wheelhouse.
That could be easily modified to use a delay, then he'd hit a looper to loop that through the rest of the song, and the main heavier guitar would just be overdriven without delay with that loop playing in the background.
I heard "Thunderstruck" on the way to work this morning, and it occurred to me that U2 could probably do a pretty good cover of that.
No one in the crowd would expect it.
He used some form of Hiwatts for parts of ATYCLB, I think.
For UF and Joshua tree I'd guess that the AC30s did almost all the heavy lifting, with one of the Fender amps doing the shimmer effect. That's just a guess though.
I will say that I have seen even critics of PRS guitars say that the PRS SE One is an all-around nice guitar, most likely because the aesthetics of it are quite a bit more restrained than many other PRS guitars.
I have never played one but I've never really come across anyone that had anything bad to say about PRS from a craftsmanship point of view. All the criticisms I've read usually center around the look of the guitars.
