TonePort

The TonePort, originally produced by Line 6, was a USB audio interface primarily marketed towards guitarists and bassists for recording and practicing. It combined hardware and software to emulate various amplifiers, cabinets, and effects pedals.

Key features of the TonePort included:

• USB Audio Interface: Allowed connection to a computer for recording audio.
• Hardware Input/Output: Typically featured an instrument input (usually 1/4 inch), headphone output, and potentially line outputs.
• Software Emulation: Came bundled with software that modeled a wide range of guitar amplifiers, speaker cabinets, and effects. This software, often named "Gearbox" or similar, allowed users to dial in specific tones.
• Direct Monitoring: Enabled near-zero latency monitoring of the input signal, minimizing delay while playing.

The TonePort line was eventually superseded by Line 6's POD Studio range, which offered similar functionality with improved features and updated software. However, TonePort devices remain in use by some musicians due to their functionality and the sounds they can produce.
