i have a Marshall MG50 DFX which im happy with. however i am thinking about adding to the sound and practicality with some pedals. there are some nice on-board effects, but playing live can be a bother since i'm not able to change sound mid-song, except between clean and overdriven. also a nice overdrive boost for solo's is needed. any ideas? price isnt really an issue, though im quite frugal and like a bargain! i have a behringer v-amp 2, which is a multi-effects box, but find that some of the sounds, and also the delay between effect change isnt up to scratch.
