Vintage DOD Overdrive Preamp 250 — LF351N Chip

The listing

Vintage DOD Overdrive Preamp 250 in good working condition, with normal cosmetic wear consistent with its age — scuffs and finish wear, no functional issues. Fully operational. This one's got the desirable LF351N op-amp — the chip collectors and tone-chasers specifically seek out for its smoother, more musical overdrive character compared to later versions of the circuit. A legendary, simple, single-knob overdrive that's been a go-to for decades for pushing amps into warm, gritty breakup. A great-sounding piece of pedal history for anyone chasing that classic DOD grit.
