Enormous Door BSO Overdrive


If you’ve been using a Ouija board to channel the ghosts of guitar greats who have passed on, then rejoin the 21st century, because the BSO is your conduit.  A work horse on any pedal board, the BSO can forge an infinite spectrum of sounds; from bluesy crunch to full tilt overdrive.   Designed to compliment any style, as well as any rig, the BSO is a classic overdrive designed to fill your sound with the spirit.

Designed around the legendary Burr Brown OPA series op amp for Hi-Fi operation and maximum reliability.


Symmetrical clipping for a more traditional sound.  Asymmetrical clipping is more aggressive, enhancing attack and articulation on leads.
