Pedals that stack with the PRS HDRX 20 20-Watt Guitar Amp Head

Dallas Rangemaster Treble Booster

The HDRX 20's driven, modern breakup gives the Rangemaster's germanium treble boost a heavier amp voice to push into.

ProCo RAT 2

The RAT's dark, cutting distortion pushes past what the HDRX 20's own studio-driven metal gain gets you on its own.

MXR Distortion+

Stack the Distortion+'s germanium grit ahead of the HDRX 20's own modern, driven breakup for two distinctly different flavors of saturation.

Tech 21 Boost Fuzz Metallic

PRS HDRX 20 20-Watt Guitar Amp Head's own edge of breakup character is the real reason this is worth trying

MXR Phase 90

Let the Phase 90's classic sweep trail the HDRX 20's modern, breakup-ready channel for psychedelic movement on top of the drive.

Keeley KE-Suprod

PRS HDRX 20 20-Watt Guitar Amp Head leans toward edge of breakup, and that's a real, usable character to pair with

Electro-Harmonix XO Deluxe Memory Man

Keep the Memory Man's lush analog echo in the HDRX 20's loop, clear of the amp's own driven, modern breakup. — goes in the amp's FX loop (or last, into a clean amp)

Alexander Pedals Radical Delay

Keep the Radical Delay's arpeggiated, ambient repeats in the HDRX 20's loop, clear of the amp's own driven, modern breakup. — goes in the amp's FX loop (or last, into a clean amp)

Pigtronix Philosopher King

Run the Philosopher King before the HDRX 20 for compressed, driven sustain before the amp's own studio-metal gain reacts.
