Hello i recently bought a Spider IV 15 watt, i got an epiphone les paul special(first electric guitar), I wanna get a decent metal tone, i looked up on the internet for metal tones. i tried them but when i hit more than 1 string the sound can't be understood, i mean it's noisy and unclear, Can you guys tell me about some settings? is it the amp's fault or do I need some good settings? i want a tone that can be understood, i don't want any bad noise when im hitting 3 open strings, I am very dissapointed, what do you recommend?
