Hi Phil. Yes, it happens only when activating an effect on the M13, even if its only a device that does not change values unless by an external expression pedal like for instance volumepedal (at max) or pitchshifting or whatever similar. Naturally all kinds of boosts and distortions-change or increases the volume, but since I use mainly use reverbs and delays, it is a problem for me. I understand the reason for having unity gain, but since that continuity of volume does not work on my M13, it is useless to me and I would rather have the option of compensating the volume before sending it onwards. I think I might have maybe 2 weeks left on my warranty, is there any other solution, can it be tweaked in hardware internally somehow?

I dont have access to other amps or M13 devices so I can compare if this is a unique problem with my unit.

Thanks

Mike

Hey Hugo. So, you are telling me this volumedrop is normal and that I have to put it in DSP bypass to get rid of volume differences? Then what would be the point of having true bypass in the 1st place?

Phil has just pointed out that the M13 has no master volume in settings,  because you are aiming at unity gain. Does that not counter what you are now saying. Why aim for unity gain if there is no transparancy between signal in/out.

What I am saying is that my M13, as fx are activated, is lowering the volume of everything going through the fx, even non-fx like flat eq, volume etc. I dont see why it would have to be lower in output, in comparison to the original signal (I would consider that "tone loss").

I dont see why I have to use a separate boosterpedal in the m13 fx-chain just to compensate for the lower signal when turning it on/off. DSP bypass always on with a lower signal output seems odd as it would void using true bypass for clean signalflow. I could use an entire fx-slot just to use a booster in the m13 itself, but I would lose 1/4 devices and I would always have to activate 2 at a time.

Thanks for acknowledging and helping me clarify the issue with the m13. I will use the booster in the fx-loop to even the volume drop until I find another solution. Please consider adding a final mastervolume feature for adjustment/compensation of volume (it could be hidden if it would compromise other users experience) to the next firmware relase, that would take care of the issue.
