I have a Les Paul Standard by Epiphone and a Marshall amp, its the cheaapest one with only Gain, Contour and volume controls. THe problem is, that to get my slash sound, the sound like on Sweet Child o Mine, i have to put the gain at 10, contour at 10, then both tones at 10 on my guitar. BUT!!! If i play a cord with these settings the chord goes... mushy, scrabbled, unclear. Doesnt sound right, because my gain is up so high. This is the same when i pick 2 different strings at once, the sound goes all distorted. So, how do i solve this, i know i have a cheap amp but would an effects pedal fix this? could i put the gain down on the amp and turn summin up on the pedal? or is it basically impoissible for my amp to get that good sound?
