My action on my acoustic guitar is OBNOXIOUSLY high, I just got this acoustic and I can still return it, but I got a really good deal so i'd rather not. A good friend of mine who knows about gear building told me to get a new bridge and put it on. Where do I start and should I do it myself or just return it (last resort)?

Thanks, keep in mind, it's a left handed guitar, does that make a difference for the bridge to buy?
Im not sure you'll even need a new bridge, i took the bridge out of my acoustic and sanded it down a couple of mm's (on a flat surface) and also tightened up the truss rod. Works fine now
God and Country are an unbeatable team; they break all records for oppression and bloodshed.
a bridge job is a very delicate thing and cannot be taken lightly

i would go to a professional and let him do it.
Due to recent cutbacks, the light at the end of the tunnel has been turned off
All you need to do is take out the saddle, sand down the flat part, and glue it back in. A new bridge would be too much i think.
