Review: Positive Grid RIFF Interface

recordingmag.com

The Positive Grid RIFF USB Guitar Audio Interface is a portable, sleek solution for guitarists on the go. Its sturdy metal build and intuitive controls make it a reliable companion for practice or quick recording sessions. The RIFF integrates seamlessly with BIAS FX 2, offering extensive sound modeling options that cater well to guitarists seeking versatility. However, it disappoints in versatility, as it's limited to direct guitar or bass inputs, leaving vocalists and acoustic players in the lurch. At $99, it's a great buy for BIAS users but may not fulfill all recording needs.

Positive Grid RIFF Review - Premier Guitar

premierguitar.com

Positive Grid's RIFF interface shines as a budget-friendly entry into home recording. Its standout features include a streamlined design, easy setup, and compatibility with any DAW or plug-in. The lack of a power supply or batteries makes it ultra-portable, while the 24bit/96kHz recording quality ensures clarity with minimal latency. However, the preamp emulations might leave tone chasers wanting more, as the differences are subtle. Bundled with BIAS FX 2 LE software, RIFF is a practical choice for musicians seeking a straightforward, effective tool without extra frills. An excellent value for its price point.
