The PreSonus Studio 26c is a 2×4, 192 kHz USB audio interface that comes with Studio One Artist and Ableton Live Lite DAW recording software. Users praise its compact build, correct features, and ease of recognition by the operating system without requiring hassle configuration. They appreciate the quality of the preamps and 4 TRS outputs for working with electric guitars, as well as the included software bundle. However, there are recurring complaints about the advertised free software not being included with the 26 model. Some users also report issues with weird squeak feedback and fluctuations in sound, while others are dissatisfied with the lack of controls on Alsamixer for Linux users.

Pros:

* Compact and built with correct features
* Easy recognition by operating system without hassle configuration
* Quality preamps and 4 TRS outputs for electric guitars
* Included software bundle

Cons:

* Advertised free software not included with 26 model
* Issues with weird squeak feedback and fluctuations in sound
* No controls on Alsamixer for Linux users
* Some units may arrive without a box, increasing the risk of damage during shipping

Note: Some users have reported issues with customer support, particularly in regards to the advertised free software not being included with the 26 model. However, these comments were not widespread enough to be considered a recurring criticism. Additionally, some reviews were excluded due to being off-topic or irrelevant to the product’s performance, design, and value.
