Pedals that stack with the Blackstar Unity 250

Dallas Rangemaster Treble Booster

The Rangemaster's germanium treble boost stacks right into the Unity 250's midrange-forward preamp for extra cut and grit.

Colorsound Overdriver

Push the Unity 250's gritty, stage-ready preamp drive with the Overdriver's transparent treble boost and it opens up without choking.

ProCo RAT 2

The RAT 2's bright, cutting distortion pushes the Unity 250's gritty, stage-ready drive into much heavier territory.

Boss CE-1 Chorus Ensemble

Run the CE-1's lush, rich stereo chorus after the Unity 250's gritty, stage-ready preamp drive and the modulation has real saturation to color.

Dunlop MXR M299 Carbon Copy Mini

Keep the Carbon Copy Mini's dark, ambient slapback delay in the Unity 250's loop, clear of the amp's own gritty, stage-ready drive. — goes in the amp's FX loop (or last, into a clean amp)

MXR Dyna Comp

The Dyna Comp's classic squash evens out pick attack before the Unity 250's grit and punch take over.

Electro-Harmonix XO Deluxe Memory Man

The Memory Man's lush analog echo belongs in the Unity 250's loop, clear of the amp's own gritty, stage-ready drive. — goes in the amp's FX loop (or last, into a clean amp)
