The Boss PS-6 Harmonist is a powerful pitch-shifting and harmony pedal that goes far beyond simple detune effects. It can generate harmonies in musical intervals, shift your pitch up or down, add subtle detune thickness, and even apply a basic pitch-correction effect. The Freeze feature lets you hold a pitch or harmony for dynamic textural playing, while intuitive knobs make it easy to dial in usable sounds on the fly.

The DigiTech Death Metal pedal is a no-holds-barred distortion stompbox built to deliver punishing, high-gain tone with serious attitude. It gives you massive saturation right out of the box, yet also lets you fine-tune the lows, mids and highs so your sound doesn’t just become a wall of noise. The dual-output design, one for amp, the other with cab emulation for direct-to-mixer or recording, is a savvy addition for rig flexibility. Whether you’re playing grindcore, thrash, or just want your guitar to roar, this thing is built to push boundaries.
