Don't take your guitar to a tech
ummmm well dont take it to just anyone ask lots of questions before you do so
the opening comment is rather strong i feel but again you must have had some reason to state it maybe a bad meeting with one of those out of the box parts fitters

who seem to work out of many of those s a l e s stores.
Thers a lot more to guitar setup and building then just a jazzy instructional video with some person grinning alot and trying to look nice for the camera.
Sure theres some good text, audio, and video out there, but please please just use this stuff as a guide to assist you and your knowledge in learning how things work then take the guitar to someone with a good reputation and a lack of ego someone who aint got his/her head stuck where the sun dont shine.
If you are trully intrested he/she may teach you a few tricks over time and with practice the correct tools for the job and some inner guidance and intuition you too will be able to repair your guitar but before then please dont judge all by what the fools do as this casts a dim shadow upon good people who are true pros not everyone is out to rip you off.
Many people are too cheap when they shouldnt be and too over the top at other times pennywise and pound foolish.
They also like to chew the fat for too long as well many skilled techs dont need to be impressed by what you own or what your political views on the world are you may get the chance to talk about all and share this with them if you get to know them in time but before then K I S S keep it simple stupid take the knowledge you learn from those videos and web sites in with you it may assist you to identify the machine heads from the bridge saddles THEN KEEP IT BRIEF tell them what you would like listen to what they have to say agree or disagree then and settle a time for the job to be picked up and what the estimated price will be if you are reasonable allow a little extra time for blow out in the job coming back or the cost being a bit more remember there are many more also out there who wastes these luthiers time with irevelance so times this by many people and then you know why the guy will say the job aint finished on time.
i could talk on this all day but thats it from me for now hope it was of some help to anyone who was willing to listen ??
