Critic Reviews

Positive Grid Spark CAB review | Guitar World

guitarworld.com

The Positive Grid Spark Cab is a standout addition for both existing users and those new to the FRFR cabinet scene. Its lightweight design and robust feature set make it ideal for modern players utilizing digital modelers. However, it does lean a bit bass-heavy, which may require some EQ adjustments, especially when paired with smaller amps like the Spark GO, which can be precariously unstable on top of the cab. Overall, it’s a well-constructed and affordable option for enhancing your live rig or recording setup.
