Every now and then I'll come across a set of short springs and they're such a bitch to adjust I always just pull them immediately and put in a "regular" set. I just did an RG7CT [99' model] with them and figured a few of you guys are experiencing the same. Here's the difference
You can clearly see how gold toned the short spring is compared to the normal. In a setup the difference between 3 of each can be as much as 3/4" [20mm] in where the position of the spring claw is. The short spring remain in a nearly closed position making them so finicky to adjust. These short springs will counterbalance a set of 10's [in fact I've used 2 short springs in arrow formation with 10's] and 11' gauge strings without problem, and possibly 12's or higher, but for 9's they're just a pain.
To swap springs, with the guitar in correct current setup, pull one spring at a time and replace. When all are done start screwing in the claw under the guitar comes back into tune, fine dial in all the details and you're done. Since these shorties were original issue you'll probably find the claw screws will be biting virgin wood when you screw them in to the proper depth for the longer springs. Just screw hard and they'll get there [good advice in bed too]. ;)
**A closed spring requires more force to open than a open spring**
**The more open a spring the easier it is to open even further**
**Always let springs settle for an hour after adjustment and retweak if necessary**
**Springs retain a "memory" and need to settle to develop new memory**
