Independent shopping perspective
The Korena take
Flex Prime puts amp modeling, effects, cabinet and microphone models into a compact guitar and bass pedalboard format. Its 4-inch touchscreen supports direct rig building, while three assignable footswitches and the onboard expression pedal keep key controls underfoot. Presets switch without gaps, and each rig can use up to 14 blocks. Wi-Fi access adds cloud sharing, firmware updates, and browser-based editing; Bluetooth and the streaming practice tools support playing along with tracks.
Strong match
Who this is for
