Re: Can you suggest a........
What do you mean by heavey metal. If you want high output, tons of gain and the likes i suggest a custom, or maybe even a JB. JBs are very versitle and would do you well in the bridge of a nice LP. They tend to be a little think in some guitars, but in LP with the right eq they will scream. A custom has a little less uppermids spike and more of a bottom end for a PAF on steroids kind of sound. Ome other choices would be a 59 for some more of a classic rock/ ac/dc metal sound. Another may be an Invader, however, I find invaders to become a bit muddy in LPs with their huge low end. If you post some of your influences and more specific type of sound you want, im sure a lot of the metal guys around here can help you. Also, what amp are you using? Any pedals? These can make a huge difference in the tone you get.
Good Luck,
Brian
