hi everyone, i made a big mistake and not sure how to fix it. i really hope im not the first one to do this but, i bought not one but two slide guitars . one 3 string and one 4 string. i did not know the action would be so high that you cant fret. both are well made nice guitars but i want to  be able to fret and slide. looking for ideas on how to lower the action. maybe install hardtail bridges ? any advice would be greatly  appreciated. thanks , r.j.
