i have a boss me-20 multi effect pedal and when i play it through headphones,it sounds nice but when i play it in my amp it sounds like crap.my amp is a fender fm25 dsp and my guitar is a squier strat lol. i think it my amp thats making the me-20 sound bad. any ideas? i was thinking of selling my amp and buying a roland cube 20x. does the cube sound good and handle pedals well?
