Product Description
The 29 Pedals EUNA (Elite UNity Amplifier) is a masterclass in signal preservation. It is not a standard buffer—it is an input driver built from the ground up to protect, condition, and sweeten your guitar's raw signal before it ever hits your pedalboard. By replacing conventional, tone-sucking input buffers with console-grade circuitry, EUNA eliminates the mushy, dark degradation caused by long cable runs and true-bypass switching, restoring your instrument's natural "snap," touch sensitivity, and dynamic range.
Designed to sit first in your signal chain, EUNA boasts an massive +18dB of input headroom with extremely low total harmonic distortion (THD). This means fast transients pass through completely unclipped, providing a flat frequency response from 10Hz to 50kHz that translates to pure, uncompressed tonal sweetness.
Three Sweetening Filters
EUNA features three highly musical, interactive toggle switches to tailor your rig's base tone without introducing artificial EQ artifacts:
-
Harmonics: Pushes the upper "air band" where guitar harmonics live, adding a beautiful, tube-like chime and clarity to your top end.
-
Bright: Introduces an articulate, subtle brightness to help your signal cut through dark mixes or compensate for cable capacitance.
-
Low: Adds a tight, controlled low-end bump—perfect for restoring body lost down the pedal chain or adding a sweet, authoritative "oomph" to your rhythm tone.
The Alt-Path Insert Loop
One of EUNA's most brilliant features is its active-low effects loop. Traditional buffers notoriously ruin the impedance relationship between your guitar and vintage-style fuzzes or wah pedals. EUNA solves this completely: when the pedal is turned OFF, it automatically activates the built-in insert loop, routing your guitar direct-to-fuzz with zero buffering. When no pedals are plugged into the loop, turning EUNA off puts the entire unit into true-bypass mode.
Studio-Grade Construction & Road-Ready Utility
-
Audiophile Architecture: Built like high-end recording gear using a 4-layer PCB with 2oz copper, WIMA film caps, 1% thin-film resistors, and zero electrolytic capacitors in the audio path. The power supply side is entirely isolated from the audio path with dedicated shielding and a proper star-ground configuration.
-
WHATEVER Power Supply: Equipped with 29 Pedals' proprietary power circuit, EUNA accepts anywhere from 7.5 to 35 volts of AC or DC power in either polarity, regulating it internally with absolutely no change to your tone or headroom.
-
DIY & Mod Friendly: Features a socketed op-amp for easy chip rolling, along with an easily serviceable chassis that lets tech-minded players tweak the audio path without disturbing the power supply.
