29 Pedals makes utility stompboxes that help guitarists preserve and condition their tone.
The EUNA was their first “hit,” a unity amplifier with an input driver that replaces a conventional buffer and that solves problems related to extra long cables or incompatibility between your wah and fuzz pedals (through an alt-path insert loop).
The brand new OAMP is a similar concept, but instead of being an input amp, it’s an output amp with a lot of headroom – and yes, its function is also to replace buffers, condition your tone, but it can also drive your amp with up to 29dbs of boost. It features also a knob for presence, one for low end, and two 3-way toggle switches with different settings for the Input and Output.
For a more technical and deep description of the OAMP, we’ll let the builder description do the writing – you can find it at the bottom of the posts.

OAMP is the Output AMPlifier from 29 Pedals.
An output driver that replaces conventional buffers, line drivers and preamps, OAMP makes up to 29dB of gain, provides final signal conditioning and sweetening, and will drive lots of cable or capacitive loads. OAMP will drive down to 600 ohms! The alt path is similar to EUNA, it’s active when the pedal is OFF. This will allow you to swap to a different output driver and create a sort of local channel-switching on your pedalboard. Also features the 29 Pedals WHATEVER power supply, which accepts 7.5 to 35 volts of AC or DC in either polarity with no change in tone. EUNA is made by 29 Pedals in California.
OAMP has strong enough drive to drive several loads, passive splitters are no problem. You can manage the 29dB of gain using the two toggle switches, each stage has low and hi gain settings as well as a fixed tone filter. The Level control sits between the two gain stages and doesn’t affect the overall input and output impedances. The Presence control dials in some classic amp-style mid-scoop to tailor the midrange drive, or simulate an amp when going direct.
