{"content": "Here's the story of one of the most fascinating overdrives ever made — a pedal so unusual that even its creator didn't fully understand it.
The Discovery
Josh Scott found something extraordinary at Bob Meyer's workshop: a Germanium Overdrive prototype that wasn't meant for sale. It was a testing unit built to analyze germanium transistors, handwired by Meyer himself — the inventor of the Big Muff. The device used a triangle enclosure with a socket underneath where different transistors could be swapped in and out.
Scott describes seeing it as walking into a time portal. Meyer's workshop is filled with vintage Electro-Harmonix gear from the '60s and '70s, and this unit was one of many prototypes Scott uncovered during six years of research for his upcoming book with Daniel Danger.
From Test Unit to Product
The Germanium Overdrive started as something entirely different than what it became. Bob Meyer designed it as a transistor analysis tool — literally a germanium transistor tester. Lou Deng, who worked on the famous 16-second delay, later helped transform this testing unit into a marketable product.
There was no volume control on the original prototype. It only had three controls: gain, bias, and volts. The bias knob controlled voltage running through the single transistor, not the entire circuit. Voltage (or sag) powered the whole pedal, while gain acted as an input gain at the base of the transistor — essentially controlling input signal voltage.
The final version required tweaks to eliminate dead spots and added a bypass switch.
An Unexpected Connection
Here's where things get interesting: Scott realized this pedal shares a direct connection to his own company's history. The Germanium Overdrive used the same exact enclosure as JHS's discontinued Double Barrel — same color, same case. When Electro-Harmonix went bankrupt, Mike Matthews rebranded the remaining inventory as New Sensor and began selling enclosures, parts, and foot switches.
Scott bought these original New Sensor enclosures for his early pedals. The Double Barrel was built in this very enclosure, using parts from the same source. It's a wild coincidence — two different companies building completely different products from the same foundational pieces.
This pedal literally helped build the company that made it famous.
Why It Was Discontinued
Scott announced that the Double Barrel has been discontinued after selling tens of thousands of units. He's now working on revamping the two-in-one format, with three new versions dropping this year. The decision wasn't about quality — it was simply time to move on and try something fresh.
Critics might note that discontinuing a popular product risks alienating loyal customers who preferred the original sound signature. But Scott argues the new iterations are superior in routing and flexibility.
Bottom Line
This piece is strongest when Scott shares the behind-the-scenes detective work of finding these prototypes — particularly the moment he realized his own Double Barrel shared DNA with the Germanium Overdrive. The weakest element is the lack of clarity about exactly what Meyer was building in the '90s; even after two conversations, Scott couldn't nail down the purpose. Still, that mystery makes the story more compelling — some gear stories are best left unsolved.
