Pedals that stack with the PRS HX 50 Head

Carl Martin Atlantic Chorus

Where this leans warm, PRS HX 50 Head answers back bright

Electro-Harmonix Andy Summers Walking on the Moon

PRS HX 50 Head's bright balances out the warm tone

MXR Analog Delay

Keep the Analog Delay's warm, slapback echo in the HX 50's loop, clear of the amp's own tube-driven distortion. — goes in the amp's FX loop (or last, into a clean amp)

Empress Echosystem

Keep the Echosystem in the HX 50's loop — complex digital delay and reverb beyond the amp's own transformer-driven distortion. — goes in the amp's FX loop (or last, into a clean amp)
