I would suggest a
Roland Cube 20xlIt has both Clean and Lead channels, a built-in tuner, aux input (To plug in your mp3 player), recording/headphone output, a foot pedal input (For switching between channels, effects). It also has Reverb, Chorus, Delay, Spring (?), Heavy Octave, Phaser, Flanger, Tremelo and Solo settings/fx. It also has 5 different distortion settings (along with an acoustic simulation setting), a gain control and 3 equalizer knobs.
Oh, and also a power squeezer switch.
Not to mention it sounds great and is totally worth the money.
This guy can probably sell it to your for $110/$120, I bought it for $125 from him when he was selling it for $150.
But then again, the Roland Cube 20XL is the only quality amp I've owned thus far. So there might be better amps out there for your money, but I don't know.
