I have a yamaha electric guitar (not a strat, not pacifica, something else) I must say, it has a very cheap tremolo but the pickups are good (dimarzios). anyhoo, i am thinking of installing a sustainer .. some people told me its a nightmare on a cheapo guitar. (a 22 frets fretboard, and 2 pairs of pickups). I dont want to put it on my other guitar because it too expensive and i dont want to mess around with it. what do you think??
