Porter is a headphone amplifier equipped with a standard 1/4-inch jack. Users can easily switch effects using their feet or play with short jumpers. Porter is designed to shape the sound for an amplifier-like response, after which the distortion pedal produces the desired tone.

Practice Effectively

Porter is a straightforward tool with no unnecessary applications or updates. It offers a perfect balance of controls, indicators, and inputs. Additionally, the belt clip is sized to fit securely on your guitar strap.

Designed for both guitars and basses, Porter delivers exceptional sound quality. The slider switch lets users choose between guitar mode for a sharper, tighter response or bass mode for richer, extended low-end tones.

The micro USB port serves dual purposes: it works as both a charging port and a line input (with the included adapter), enabling you to jam along with music or backing tracks.

Longevity Comes Standard

The design goal for Porter is that users will only need to purchase it once, enjoying a lifetime of reliable use. Featuring a rugged aluminum casing, a riveted steel belt clip, and rechargeable, replaceable batteries, Porter is built to last. The unit has no external plugs, and its components are selected for durability, ensuring that wear and tear won’t impact performance. Additionally, complete design documentation will be provided, allowing users to repair or customize their Porter, keeping it in pristine condition for years to come.
