Audio & Music Crowdfunding Project

Porter is a headphone amplifier with a standard 1/4-inch jack. Users can switch effects as usual with their feet or play using short jumpers. Porter adjusts the sound to provide amplifier-like response, and then the distortion pedal will produce the desired sound.


Practice Effectively

Porter is a tool without applications or updates, it features just the appropriate balance of controls, indicators, and inputs. Besides, the belt clip size will fit perfectly on your guitar strap.

Porter is designed for use with guitars or basses, delivering exceptional sound quality. Users can use the slider switch to select the guitar mode for a tighter response or the bass mode for extended low-end tones.

The micro USB port doubles as a charging port and a line input (with the included adapter), allowing you to play along with music or backing tracks.


Longevity Comes Standard

The designers hope users will only need to purchase Porter once for a lifetime of use. Porter features a sturdy aluminum casing, a riveted steel belt clip, and rechargeable and replaceable batteries. Porter has no external plugs, and the chosen components are designed with longevity, so wear and tear won't significantly affect Porter. Additionally, users will receive complete design documentation, allowing them to repair Porter themselves or customize it to keep it looking brand new.
