Got in one of my SE's to fix a shorted out pot, and do some other minor mods, and ended up having to cut a couple of wires short and splice/solder in some other wires to make up the length. Is that a bad thing to do? I can't think of any reason why it would be, but there doesn't mean there isn't one. I soldered all the connections and covered everything with electrical tape and/or shrink wrap.
In a related story, I also put treble bleed caps on my volume pots - I noticed that I was losing a lot of treble when turning my volume down, didn't know what was causing it, and it never occurred to me that there just weren't bleed caps, I thought that was a standard PRS thing. But, anyways, caps added and I'm sparkling away at all volumes now. Also changed out my tone cap on the neck pickup to a .01 uF from the stock 0.22, which has really brought that pickup to life. Previously I also added a .0047 uF cap to the hot lead of the neck pickup, which cuts out some of the deep bass. Pickup has a much tighter, more articulate tone now, without being too bright. I usually set my amp up for a thick tone with the bridge pickup, so the neck can get pretty wild, and this has tamed it.
It kind of amazes me all the little tonal tweaks that can be done with a soldering iron and some cheap capacitors. Especially on an SE guitar, where it's not a big deal to mess with the wiring.
