Rylee & I riff sound

Trying to recreate a specific sounds from this track.

The riff that carries the track has two parts, a very distorted guitar on top ( how to get this tone is covered loads ) and a sort of arp almost mallet like sound underneath? It starts at 0.01 - continues the whole way through with the feedback sound coming in at the second half of every bar.

Any ideas how i could get something even remotely similar? A chain to alter drum or synth sounds like this?

Thanks!
