I Have A Question With The Distortion

Hey guys, I'm a newbie so I don't know much about guitar.
I have an electric guitar and a metal muff pedal
Here's its picture:

I think this one is a pretty good pedal.

But when I play my guitar with the distortion on, it was like ... hmm I don't really know how to explain it. Let me say this way, when I play only one string, it sound very good. but when I play like 2 string together, it's a little hard to hear the sound, three strings together, harder to hear the sound and so on.
If I play 6 strings separately, but it's like really fast, like the sound of the first string I played still loud and I play second string, then third string, I completely cannot hear the sound of the string, just the sound of distortion only. When I ask 1 of my friend, he said maybe it's because of the amplifier. I was planing to get a new big amplifier, so will it make my sound better?
