Let me clearly state that if the clean sense is set right, then activating a distortion pedal does not cause a surprising volume jump.
With analog equipment this is handled by the stomps volume.
On th Profiler this is not necessary, once the clean sense is set.
The stomp volume is still available for a dedicated solo boost etc.
The Profiler is designed to produce a unity volume across various situations, when clean sense is set right and the other bipolar volumes are set to their middle position. Depending in the situation, and because situations and guitars are individual, levels might need 2 or 3 dB of adjustment.
The gain into the stomps are also like on the original, I have tested this quite some times.
If somebody has still problems of this kind, please post here.
