so right now i'm really leaning towards this modded epi valve junior that's for sale near me. it's only $200 and has a tone switch, three way voicing switch, and fat boost. the voices are based on fender clean, vintage marshall OD, and a high gain amp. i'm going to try her out this weekend but with the extra money i'll have (which is approx. $100 to $150) i'm thinking i might get a pedal like a tube screamer or fuzz face that will get me tones that i can't get out of the amp. any suggestions on pedals or what i should get? fyi the amp has new tubes also....i think there JJ and sovtek or something like that.

thanks for anything suggestions!
