I dove right in after work this evening, pulled out the S1520 and just laid the edge pro in there to see how it fit. Well, it's pretty much a direct drop in.
I could see it would limit raising the term depending on how high the posts were set at and I just had to eyeball everything at this point. I decide to go ahead and install it. Looked for the extra set of Ernie's I had in nines and couldn't find them anywhere. Gave up and pulled out my last set of EB Cobalts but they're 10's. I have extra springs but I didn't want to waste a $10 set of strings knowing I was going to have the guitar apart again for a pickup swap and fretwork. Screw it. I'm also finding I prefer 9's as of late but I'm impatient and I really wanted to get this guitar together sooner than later.
Managed to get everything on, turned the stock screws all the way in (the brass ones included with my KGC brass claw weren't "thick" enough and one flew straight out when I attached the first spring) and started tuning. Got everything lined up and tuned. Looks great on the guitar!
Next to the Lo Pro...
Test fit from the back...
Installed and tuned. Not much room up front but plenty in back. If you want to really pull up on the bar a significant amount, you'll have to do a bit of filing. But the width is fine and removing a few mm up front will give you a fully-functioning term. It dives like the stock lo pro.
I plugged her into a little Yamaha THR10 to noodle really quick and I started out on the clean channel. Have to say I really like the Cobalts. Just great strings and I use them on all my guitars unless I know I'll be taking things apart frequently. THe QM's sounded surprisingly good and reacted to volume adjustments really well. Very vocal. Turned up the master volume and switched to crunch, got some strange low end noises which required adjusting the amp. Not sure what's causing it but it was fine after I rolled off the gain just a smidge. I'll test it out with the Eleven Rack tomorrow but I'm suspecting the QM's don't handle high gain well.
I have to say, I REALLY like this guitar. Action is about 3/32nd's and it took almost nothing to set it up. Zero buzzing anywhere. I didn't do any fret work on this guitar like I did the S540 as I was planning on a full-on fret dress by a luthier as there's wear. It's hard to see but I can feel it and I figure it'll just get worse unless I take care of it. The entire guitar just feels fantastic. Balanced and very light. And sustain is better than any of my other S guitars including the S540. Every one I own is an AANJ. It's not as "fat" as the S5470 but it does sing and the pickups have a nice vocal quality to them. As is, it's a very expressive guitar and very easy to play. I'm finding more and more that I'm liking the Wizard neck as it seems easier to play. Much more so than the Indonesian neck which I believe is a Wizard II shape. Maybe the guitar is just settled in more. Dunno, but I get the same vibe from the S540.
There are a few of these S1520's for sale if you look around, one for a very good price and in good condition at GC. I thought about picking it up but I've bought enough guitars over the last month. Just a great guitar especially considering what they're going for currently.
