Your Octave Fuzz Search is Over | Jam Pedals Octaurus LTD

Early-60s NOS silicon transistors, turret-board point-to-point construction, and an octave that blooms across the entire fretboard. All wrapped in olive drab suede. Welcome back to Edge of Breakup.

In this episode, the JAM Pedals Octaurus LTD takes the spotlight — running into my Kauer Guitars Electroliner loaded with Lollar Sixty-Four Stratocaster pickups, into my 1957 Fender Tweed Princeton 5F2-A with a re-coned vintage Jensen P12Q.

The Octaurus LTD is the latest entry in JAM Pedals' Custom Shop line of limited edition pedals — an octave fuzz inspired by the octafuzz tones from the golden era of guitar music. But this isn't an attempt to clone the classics. Instead, JAM identified their favorite behavioral traits scattered across many of the legendary octafuzzes of the past, and set out to bring all of those qualities together into a single standalone device. The result builds on that rich lineage rather than simply emulating it.

At the heart of the LTD is a batch of early 60s NOS silicon transistors — made by Transitron or General Instrument, or both — similar to the 2N335 and 2N336. The pedal is built using intricate turret-based point-to-point construction for uncompromised signal integrity. In true Custom Shop fashion, it comes embossed in fine olive drab suede, and even features a see-through bottom plate, also wrapped in suede, with a zip for visual access to the board.

The control layout is refreshingly simple — Volume, Tone, and Gain — but two toggle switches unlock the pedal's full range of sonic dimensions. The left toggle moves between a scooped, metallic snarl and a full-bodied, harmonically rich roar. The scooped voicing is ideal for tight riffing and an even more pronounced octave effect, while the full-range voicing offers a singing fuzz quality that soars in the mix for lead work. The right toggle switches between symmetrical and asymmetrical clipping — symmetrical for tightness and precise definition, asymmetrical for a looser, more dynamic and unpredictable feel.

One of the LTD's signature traits is a clear apparent octave across all pickup positions — it retains your note's body all the way across your guitar's entire register. Roll back your guitar's volume and you get just the right amount of ring-modulator-type effect, and even then you can still play double stops and have the fundamental intervals pop out.

The single-coil clarity of the Lollar Sixty-Fours helps that apparent octave bloom across every pickup position, and into the warm, compressed voice of the 5F2-A's single 6V6 circuit and the mid-focused alnico character of the vintage Jensen P12Q, the Octaurus finds a perfect home. House tip from JAM — don't shy away from the gain and tone knobs at full throttle. That's where the strong octave and rich harmonics of this pedal really shine.

This is what happens when a builder distills decades of octafuzz history into one obsessively crafted device.
