Frequently Asked Questions

Behringer has done a commendable job; it captures the core warmth and resonance characteristic of the original, though subtle differences are inevitable due to component variations.
Yes, the resonance control goes high enough to achieve self-oscillation, though the behavior might be slightly different compared to the original due to component tolerances.
The attenuators offer a useful range, but very fine, subtle modulation might require external amplification or further attenuation stages depending on your CV source.
