• Custom cascading multistage distortion 
topology provides a wide range of tube-inspired 
drive tones
• Digitally controlled analog class A JFET input 
gain stage maximizes headroom while adding up 
to 20dB of pure analog gain
• Precision crafted DSP gain stages provide 
detailed complexity and responsiveness
• Low gain channel for smooth classic overdrive
• High gain channel for modern saturated 
distortion
• 3-band EQ with independent Bass, Middle and 
Treble controls
• Selectable post-analog gain mid-band EQ push
• Presence switch to tailor the sound for use with 
all amplifiers from dark to bright
• Optional variable-threshold noise reduction 
helps tame noisy guitar pickups
• High impedance mono input
• Mono output
• Favorite footswitch to save a favorite setting
• Expression pedal input allows the connection 
an expression pedal for simultaneous morphing 
control over multiple parameters (Expression 
mode), or logarithmic taper for smooth volume 
control (Volume mode)
• Boost pedal input allows connection of an 
external footswitch for up to +6dB of analog boost, 
or to toggle the Favorite preset on other Strymon 
pedals (Favorite Out mode)
• Ultra low noise, high performance 24-bit 96kHz 
A/D and D/A converters provide uncompromising 
audio quality
