I have a boss ds-1 distortion pedal with a fender fat strat and an epiphone valve junior combo. will i be able to play the blues and classic rock?
Yes. However...the DS-1 isn't the best for blues, and classic rock it does struggle a little with. But it can do them decently enough. One thing that might be worth investing in is a Digitech Bad Monkey or Boss OD-3 - overdrive will get you closer to those sounds than distortion will. The rest of your gear is pretty much perfect for it, though. VJs are lovely amps
