## What reviewers say

**Scarlett Solo 4th Generation** — Only one whitelisted tester, SoundGuys, published a hands-on review of this exact model (Scarlett Solo 4th Gen), testing it over one week. It calls the unit a safe, affordable, easy plug-and-play entry interface with quality mic preamps, while flagging the missing output meter, Auto Gain and Clip Safe. No lab measurements were taken. (1 sourced review.)

**Volt 2 USB Audio Interface** — Only one whitelisted tester, SoundGuys, covers the Volt 2, and only as a pick inside a buying guide rather than a dedicated lab review, so there are no measured numbers. It endorses the Volt 2 as a capable sub-$200 Focusrite Scarlett alternative with 610-style preamps. No cross-source corroboration exists on the whitelist. (1 sourced review.)
