Hey there, well i remeber replying to this thread before i went to lunch the other day and came back to find forum completely changed
ESP (Incl. LTD) are great guitars for metal especially when EMG equipped, now i know people have bad things to say about EMGs but i own two ESP LTD (F-2005 81/81 and EX400BD 81/60). The main reason i started to play guitar was Metallica, hence the ESPs were my choice, and the EMG 60 cleans and lead tones combined with a brutality of the 81 rythem tones is unbelievable.
Now your amp is as important as your guitar, i tried the HT-20 combo with PRS torero and PRS SC and with EMGS it screamed heavy metal or at least Thrash metal. now your question about the guitar so i am not gonna talk about the amps or pedals. But give ESP/LTD with EMG a shot wont regret it believe me. Good luck and keep rocking
