overly distorted on the guitar when used alone?

Unfortunately my rhythm pickup broke on my Epiphone Les Paul.

I tried playing certain songs with my gain down.

Open notes sound WAAAY overly distorted, and when you downstrum notes fast, you can hear your picking over the notes.

I am using a Marshall mg30fx.
If it is too loud and overdriving the amp, adjust the pickup height.
