Hey all!

i've been playing guitar off and on for a couple years but i never realy got into playing songs other then my own little riffs, or got into detailed info about Amps and pedels, processors.

Anyway, i have a Digitech RP250 processor with a Line 6 spider 3 75 watt amp. I'm trying to set my amp up to go with my processor. I plug my headphones into my processor and i get a great sound, but when i hook the processor up to my amp i cant get near the quality sound as my processor in the headphones. Any suggestions on settings or lack of? I'm trying to get a metal solo type sound to it.

Thanks for any replies!
