An "invisible" tool that has become essential on modern pedalboards
With increasingly complex pedalboards (often composed of many true bypass pedals), signal loss is no longer a myth: reduced brightness, a "muffled" sound sensation, less punchy attack... The EarthQuaker Devices Buffer/Preamp fits into this "signal management" logic: a utility effect designed so your guitar and amp sound as they should, even when your chain gets long.
Its particularity, beyond simply restoring brightness in the high frequencies, is to provide a very subtle boost in the low end. The result: increased dimension and foundation without altering your sonic identity or masking the character of your pickups.
Where it makes a difference: demanding guitarists, bassists, studio and stage
This buffer is aimed at all musicians who want to recover a direct, clear, and responsive sound at the end of a pedalboard, without having to compensate by boosting highs on the amp or changing the entire rig architecture. It is especially recommended if you use long cables (rehearsals, large stages), have many true bypass pedals, or feel your tone loses presence as soon as everything is plugged in.
Regarding styles, it is universal: blues, funk, rock, metal, pop, ambient... anything relying on precise attack, good chord definition, or pick/finger dynamics will benefit from a more consistent signal. In the studio, it is also a simple solution to stabilize the take, better control your effects chain response, and maintain coherence between sessions.

Questions frequently asked
Where should the Buffer/Preamp be placed in a pedal chain?
Placement at the end of the chain is recommended, just before the amplifier. With a vintage fuzz, the buffer should be placed after the fuzz to preserve its volume response. This position helps the signal maintain its definition throughout the pedalboard.
Is this buffer useful with many true bypass pedals?
Thanks to its 1 MOhm input impedance and 100 ohm output impedance, it limits the impact of cables on the signal. It can thus compensate for a loss of brightness and attack in a chain containing numerous pedals.
What power supply is required for this EarthQuaker Devices pedal?
The required power supply is a 9 V DC source with a 2.1 mm connector and center negative polarity, with a consumption of 15 mA.
What connectivity and dimensions does it have?
The enclosure has a 6.35 mm jack input and output. Its dimensions are 94 x 46 x 46 mm, which facilitates integration on a pedalboard.
Does the Buffer/Preamp alter the guitar tone?
The output aims to maintain more open highs and a clearer attack. A slight boost in the low end adds more body without masking the character of the pickups.
