It varies from guitar to guitar. Some are perfect outta the box, some may be sick puppies. At the very least, action and truss adjustment. If you change gauges or use lower tunings, the truss rod will need a tweak and if its a trem bridge, so will the claw and springs. The guitar just being here in another climate will necessitate it. Indonesia is a hot, humid, tropical climate. The States vary wildly and the neck will move more than you think. Even domestic made guitars will need a little setup attention at least every season. Sometimes the climate change may cause a fret to pop out, then its hammer time. You will always have a buzzy fret unless fixed, no matter what you do. As far as price, an average tech will charge around $60 per hour, generally (at least in my neck of the woods). Sometimes flat rates based on difficulty of the job. The chain you are looking at...I dont even know what "unlimited for two years" means exactly. Nobody I know would charge $50 for two years of setup services....unless they are GC, cause their setups involve eating sandwiches.
