I have just got a new amp yesterday as an early christmas gift (in the title) and I have a few questions about it.

1. It doesn't make a good amp for my guitar. . . No distorion on the amp, but I use my Digitech RP250 with it.
Question: can I get better sounds if I upgraded to a better pedal? (ex. distortion)

2. In the back of my amp, I can hook up my microphone and two other instruments at the same time.
Question: How would the quality be on a electric drumset? Because I have a band practice in about a few days and my drummer wanted to use my amp with me.

**If your wondering why I got this amp it was mostly supposed to be for my **
