JHS Overdrive Preamp
Step back in time and experience the genesis of a legendary circuit with the JHS Overdrive Preamp. This pedal is a faithful recreation of an exceptionally rare, pre-"Gray Box" DOD Overdrive/Preamp (#75), one of the first of its kind ever sold. The tone is distinctly vintage, providing everything from a subtle, always-on coloration to full-blown gritty overdrive. It delivers a familiar yet unique voice—think classic DOD 250-style grit, but with an overall increase in gain and a more pronounced, unique low/mid character that makes it a must-have for tone connoisseurs.
The construction of this pedal is housed in a modern, durable enclosure, faithfully replicating the circuit's origins while offering modern reliability. The simple two-knob control set—Level and Gain—is intuitive, but the added Slider switch unlocks two distinct clipping variations, giving you versatile sonic options. The circuit is based on the coveted early V1 DOD 250 Overdrive/Preamp, replicating the loose, hand-etched PCB internals and the parts salvaged from old electronics in 1970s. JHS even modified the Level control to provide significantly more volume on tap than the original unit, ensuring it can cut through any mix.
This analog overdrive/preamp is perfect for players looking to explore the roots of "America's Pedal." Whether you need a bright, open boost for darker pickups, or a saturated, wooly distortion to front-load a high-gain amp for snarling, Yngwie-esque textures, the JHS Overdrive Preamp delivers golden-era tones in spades. It’s an essential piece of history and tone for any collector or player curious about how one of the greatest overdrive circuits began.
