Owned by the parent company TC Group, TC Helicon was founded in 2000, and since then has made recording and broadcasting/live equipment like audio interfaces, guitar pedals, effect processors, preamplifiers for instruments and microphones, to name a few. Their most noteworthy equipment is the TC Helicon GO series - a portable audio interface usable with both mobile devices and PCs - at a fraction of the price of a full-sized interface. 

TC Helicon primarily makes four products series’ - the GO Series of portable audio interfaces, the Perform Series of vocal processors with effects, the Voicelive Series of Vocal and Guitar Effects with Backing Tracks, Looping, Automation and Audio Recording, and finally, the Voicetone Series of Single-Button Stompboxes for Pitch Correction, Vocal Doubling, Echo, Harmony, Reverb and more.

GO Series
This consists of the GO Guitar, GO Guitar Pro, GO Solo, GO Twin, and GO Vocal. The GO Guitar and GO Guitar Pro are specifically designed to work with electric and bass guitars and record quality audio directly to iOS, Android, Mac and PC devices. It also has convenient outputs for headphones, guitar amp or PA systems. The Pro edition features the internationally renowned MIDAS amp. It has the added advantage of a powerful headphone output with adjustable level, and selectable thru/FX for monitoring processed or clean signal to a guitar amp or external rig. The GO Solo and GO Twin are designed with inputs for instruments and microphones. As the name suggests, the Solo has one input while the Twin has two independent inputs. These are compact audio interfaces with quality preamps with the capability to provide phantom power to condenser mics. These also feature 2 x 2.5 mm MIDI I/O jacks that allow you to connect 5-pin MIDI devices. Both the devices are powered by two disposable batteries or via a USB connection. The notable difference between the Solo and Twin is that the latter features a MIDAS preamp. Finally, the GO Vocal series is specifically designed to power condenser microphones, record quality audio directly to iOS, Android, Mac and PC devices, and has a headphone output to monitor processed audio. There is a helpful LED to signal phantom power for easy visual reference, and is powered by a  9V battery. These are some of the most portable, quality audio interfaces in the market.
