Hi Brashhh,
Couple of things to try…
1. Try the FX loop if your amp has one
2. If you still want / need to plug it into te front of your amp make sure the switches on the back are on instrument level and not Line level
it sounds like you are adding distortion ot the modulation and this may or may not have desirable results.
some modulation sounds better if you modulate the distorted tone as opposed to distort the modulated tone.
there is no right or wrong way to do it, just what works for you. I prefer my modfactor POST distortion in the FX Loop.
Cheers
