Vintage DOD Bi-Fet Preamp FX10 in very good condition. Missing the battery cover.
While the Boss FA-1 Fet Preamp pedal is now well-known and expensive-to-own, you can get a similarly sparkling tone with the DOD Bi-Fet Preamp FX10. Originally designed to boost the signal of acoustic guitar pickups, electric players soon found that it could add a great clean boost with just the slightest bit of dirt to their own playing.
