Pedals that stack with the Blackstar Unity 500

ProCo RAT 2

Push the Unity 500's transparent, mid-forward drive with the RAT 2's bright, cutting distortion and the two stack into real dirt.

Black Arts Toneworks LSTR Fuzz

Push the Unity 500's transparent, mid-forward preamp headroom with the LSTR's own scooped, sludgy fuzz and the low end turns to mud fast — control your EQ.

Beetronics Swarm

The Unity 500's transparent, mid-forward preamp headroom gives the Swarm's experimental fuzz real room to bloom.

MXR Flanger

The MXR Flanger adds a subtle analog swirl on top of the Unity 500's midrange grind, not extra gain.

Vox Valvenergy Silk Drive

The Valvenergy Silk Drive's smooth compression evens out your touch before it hits the Unity 500's own midrange grind.

JHS 3 Series Oil Can Delay

Keep the Oil Can's warbly analog echo in the Unity 500's effects loop, after the preamp's grit, so the repeats stay clean. — goes in the amp's FX loop (or last, into a clean amp)

Old Blood Noise Endeavors BL-44 Reverse

Put the BL-44's reverse swells in the Unity 500's loop, after the preamp grit, so the ambient texture doesn't get muddied by the drive. — goes in the amp's FX loop (or last, into a clean amp)
