29 Pedals JFET is a boost pedal with a new circuit and based upon the JFET transistor, long-loved in the world of audio for its similarities to vacuum tubes. As always for 29 Pedals it’s a ground-up design, from a blank sheet of paper, an effort to elevate the humble boost circuit to something refined and tonally enhanced.

The JFET circuit has three modes, N for “normal,” where a typical boost might sit in terms of frequency response, almost a treble boost but not quite. “F” adds a little more weight, and “X”, my preferred mode. “X” mode flattens the circuit all the way down to below 10Hz, giving you an incredible feeling of weight without sounding like additive EQ. The extension in the frequency response also tightens the phase and gives you an incredible, solid feel.

The L control sets the level, it’s a fader after the boost circuit and before the output driver. This means the gain of the first stage is set, and you can use the fader to set the level into the output stage, so THD, hair, and tone remain the same throughout the travel. The output driver after the fader ensures that the output impedance remains consistent. JFET makes about 19dB of gain.

JFET can be used after a buffer or input driver (like EUNA), and also can function as an always-on input driver at the beginning of the board. It sounds great following EUNA and also stacked with FLWR and OAMP. It will drive heavy loads and has high-headroom, making it equally happy at the end of your board. The same WHATEVER power input and relay-based switching as our other pedals, and instant-bypass whenever power is removed.

This company is the creation of Believable Audio, founded by audio engineer Jesse Honig in California. The company crafts precision utility pedals focused on tone integrity, high fidelity, and signal preservation—rather than guitar effects like fuzz or modulation pedals . These effects are built for tone purists and studio-level rigs, delivering clarity, noise-free routing, and uncompromised dynamics.

EUNA – Elite Unity Amplifier

A state-of-the-art input preamp designed to replace standard buffers. EUNA delivers +18 dB headroom and includes three tonal filters: Harmonics, Bright, and Low. It features a bypass insert loop that activates when EUNA is off—perfect for vintage fuzz or wah effects sensitive to buffering. Compatible with the versatile WHATEVER power input (7.5–35 V AC/DC, any polarity) with zero tone shift.

OAMP – Output Amp

Designed to live at the end of your chain, OAMP adds up to 29 dB of output gain. It drives cable runs, passive splitters, and capacitive loads with ease. Two toggleable gain stages, a level knob, and a presence control allow for amp-like voicing and tone polishing .

FLWR - Overdrive

A transparent overdrive/boost pedal with up to +45 dB of gain, the FLWR is a high-headroom utility box loaded with dynamic clarity. It features fuzz-loop switching and EQ routing for seamless integration into tone-rich rigs .

JFET & TOKI Fuzzy Driver

The JFET delivers classic JFET-type boost/drive, while the TOKI Fuzzy Driver adds rich fuzz texture, both designed for clarity and vintage flair. They round out their minimalist lineup .

Engineering & Build Details

• Effects are handmade in California, with premium PCB designs, grounding, and shielding for sonic purity. • Short trace, high-copper PCBs with no unnecessary jumpers reduce signal degradation dramatically. • Modular EQ options, insert loops, and high‑precision headroom design distinguish these pedals from standard buffered units.

Who Should Use these Pedals?

For guitarists who prioritize clarity and uncompromised tone across long chains, 29 pedals deliver unmatched signal fidelity from start to finish. These pedals are ideal for users with multiple fuzzes, long cable runs, or digital units that demand clean routing and zero tonal compromise. Nestled in Reddit threads over sound engineering, pedals like EUNA and OAMP are described as transformative gear—clearly engineered for the discerning listener.
