I'm a beginner guitarist who dreams of playing everything from Santana to GNR, Pearl Jam,Velvet Revolver, Foo fighters to Iron Maiden and Metallica. I'm thinking of getting either an mg15fx/mg15cfx or the dsl15c. I'm also open to any other amp suggestions in the 15-30 watt range. and can someone please explain to me the difference between the mg15fx and the mg15cfx??? Looking forward to your advice!!!
