Pedals that stack with the Boss HM-2 Heavy Metal

Ibanez Tube Screamer

The Screamer's mid-forward boost pushes the HM-2's already-massive metal distortion into a tighter, more focused version of itself.

Suhr Shiba Drive

Push the HM-2's saturated buzzsaw distortion with the Shiba Drive's articulate midrange gain for extra sustain up front.

Behringer ADI21 V-Tone Acoustic

Run Boss HM-2 Heavy Metal after it and the warm edge settles into something more bright

Catalinbread Fuzzrite GE

Boss HM-2 Heavy Metal leans full right where the thin tone needs it

Orange Series Phaser

The Orange Phaser's transparent sweep rides on top of the HM-2's chainsaw distortion without softening any of that gain.

Xotic SP Compressor

The SP Compressor's subtle, sparkling midrange squash evens out the attack before it ever reaches the HM-2's own massive metal distortion.

Catalinbread Epoch-Set

The Epoch-Set's warm, lower-mid tape echo trails the HM-2's full, shoegaze-adjacent metal distortion with real saturation to decay. — goes in the amp's FX loop (or last, into a clean amp)

Boss RV-5 Digital Reverb

The RV-5's spring-voiced stereo reverb trails the HM-2's full, shoegaze-adjacent metal distortion with a huge, saturated signal to decay. — goes in the amp's FX loop (or last, into a clean amp)

Walrus Audio Iron Horse V2

Boss HM-2 Heavy Metal's own full character is the real reason this is worth trying
