I certainly think that a Holydiver CAN work in this guitar, but there are also several options to move to which have less going on in the low mids, but use the same Alnico v magnet as the Holydiver, so have a similar feel and dynamics. The Rebel Yell would be a good option, which shifts things a little brighter across the board, trimming some lows and low mids and bringing a little more sparkle in the highs. Also the Black Dog is somewhat of a cousin of the Holydiver, using the same Alnico v magnet and SPN coil wire, but in a thicker wire gauge which produces a lower resistance coil and shifts the resonant peak upwards. It still has a strong midrange, but it isn't set as low in the frequency spectrum as with the Holydiver.
For singlecoils, if you want versatility for metal and fusion tones, the Trilogy Suite coils are tough to beat!
