I've always set-up my guitars personally. This is a skill I learned from trial and error way back when I first started playing. The first Jem I bought was my VWH, it was also my first floating trem. When I first tackled this task, I discovered it was a pain in the butt. That was strictly due to inexperience with floating trems. I lowered the action, tuned it, and set the intonation. Now all of a sudden the angle of the trem is off. Hmmm, what did I do wrong...WTF! So I did it all over again and again and again, get the picture. As Rich said, it's not rocket science. There are great tips here on Jemsite. If you're unsure or feel intimidated, take it to a guitar tech. For anywhere from $30 to $50 it will come back playing like a dream.
