That's strange, I think my CPU is running around 90%. Try deleting the extra amp. It was only in there as a test. You can also remove any effects that you don't find necessary. I use that as my main patch and have every effect like I have a pedal board...
As for it not sounding the same, I'm not sure. I'm using Dimarzio Area 57s' and Area 61s' in my strat. I have my tone knob wired to my bridge pickup ala Eric Johnson to roll off highs on the bridge when I want to. Hope that helps maybe?
I selected the Jeff Beckish preset once again, hovering between 90%-92%, switched to another preset, then back to yours, this time the meter went higher, I have no idea why. But I followed your suggestion, deleted the SLP amp block and the load went down to 89%. I see that this preset is wired up for several different scenes, so I might just go for the comp, one drive, amp block, cab, reverb, delay. Until I buy my RME interface, I'm using the Axe Fx as my interface, and guidelines suggest not exceeding an 82% CPU threshold when recording with the Axe Fx connected USB.
You have the amp block settings perfect on your preset, and as far as the Eric Johnson thing, I do the same thing on all three of my Strats, and even my vintage '62 has the bottom tone knob wired to the bridge pickup. I was so inspired by your Silent Night rendition that I recorded a Jeff Beck version of Auld Lang Syne for New Year's
I did it in a real hurry, though, and it wasn't too good, so I didn't bother posting it...still I had a thundering low frequency note, a pad, ambient background guitar and a Jeff Beck type lead line. Thanks for the inspiration!
