Frequently Asked Questions
The Knuckles leans more towards a specific high-gain aesthetic, while the Captor X offers broader amp and cab options; the Knuckles' noise gate is also notably better.
While the core sounds are excellent standalone, the app unlocks a wider range of cab simulations and allows for deeper parameter tweaking, significantly expanding its potential.
While technically possible, the Knuckles is optimized for guitar frequencies; bass tones will likely sound thin and lack the desired low-end punch.
