Global amp gain

[guitardoc]

I do not fully comprehend what 'normal' parameter the global amp gain corresponds to. It provides +-12 dB of relative gain - OK.

But the ranges of the parameters it might influence are not adjusted in dB:
Gain: 0-10
Master: 0-10
Input trim: 0-10

Does anyone know what the correlation is or is there no correlation at all?

Thanks in advance.

I'm guessing input trim at 0.25 or 4.0 is the same as global amp gain at -12 or +12. The input trim range (0.1 to 10.0) equates to a range of -20 to +20 dB.
