Critic Reviews

Vox Cooltron Over The Top review | MusicRadar

musicradar.com

The Vox Cooltron Over the Top Boost excels with its powerful EQ circuitry, offering impressive tonal flexibility that allows for a wide spectrum of sounds reminiscent of the classic Vox AC30. With the ability to run on standard AA batteries and a rugged design, the pedal is both practical and durable. However, it falls short on low-end response, leaving bass-heavy players wanting more depth. While it delivers bright, cutting tones ideal for rock solos, those seeking a full-bodied sound may need to look elsewhere. Overall, it's a solid addition to the Cooltron family for players who value versatility over overwhelming bass.
