1981 Inventions DRV No. 2 (LED Mod)

One of the most talked-about distortion pedals in the boutique world — in its most unique configuration yet. Welcome back to Edge of Breakup.

The 1981 Inventions DRV No. 2 Blackout, running in LED clipping mode, pairs with the Kauer Guitars Electroliner — Lollar Sixty-Four Stratocaster pickups — into the vintage 1957 Fender Tweed Princeton 5F2-A with a re-coned vintage Jensen P12Q. The JAM Pedals RetroVibe MK.4 joins from 05:18.

The DRV2 is builder Matt's new standard circuit and enclosure — heavily textured black powder coat, slightly raised logo, long pointer black knobs. But the real story is what's happening inside: this unit runs LED clipping, specifically white LEDs, Matt's current personal favorite iteration of the circuit — and it changes the pedal's character in meaningful ways.

With standard diode clipping, the DRV has a familiar compression and softness at lower gain. LED clipping rewires that entirely. At zero gain the pedal is cleaner, firmer, more open — barely clipping clean, genuinely one of the most beautiful tones this circuit produces. More output, less compression, striking clarity on complex chords that lets the Lollar Sixty-Fours breathe fully. Explored from cranked Gain with Volume at amp unity (00:23), increasing DRV volume to slam the amp harder from 01:36, brighter tones with the Cut knob lowered from 03:23, and lower gain territory with Drive at noon from 04:26. Opening the CUT knob all the way is one of the great discoveries with this circuit — an unexpectedly excellent sound that rewards experimentation, explored at 05:56.

The DRV V2 circuit itself was over a year in development. Originally engineered by Jon Ashley of Bondi Effects, subsequently redesigned by John Snyder of Electronic Audio Experiments — who also worked on the LVL circuit. Quieter, more efficient, capable of running at 9V or 18V via internal switch. Hand assembled in Nashville, Tennessee.

Into a 5-watt, single 6V6 Class A Tweed Princeton with a vintage Jensen P12Q providing warm, mid-focused alnico character, the LED-clipped DRV2 finds a sweet spot a higher-wattage amp might never reveal. The JAM Pedals RetroVibe MK.4 brings its all-analog photocell-and-bulb Uni-Vibe character back into the chain, with tap tempo, ramping, and Chorus/Vibrato modes.

This is a rig built around the edge. Every knob setting tells a different story.
