I have an Epiphone Les Paul Special II. Now the guitar cost me About 190 dollars (american). If I replace the hummies I got with the Gibson 490 Series hummies will it be worth it? I love the way it sounds don't get me wrong (I play it through a Small Fender Frontman at home with a Fender Electro Volt Cable and I put a slight touch of skin along with the pick but not to much to create a harmonic. Maybe that'll give you an I dea of the tone? Maybe not?) but, It could be clearer and is it possible to put locking tuners on a guitar? It gets great sustain (mahogany body rosewood fingerboard bolt on neck and a stop bar tail). what would be my best move?
