Re: OT: setting the gain

[Michał Wiernowolski <mihalw@gmail.com>]

I like the idea with a mixer. The G5 has a separate XLR output, which 
can be setup pre-fx. You could pan the xlr output hard left and the L/R 
1/4" output hard right and compare the levels in left and right channels 
of your mixer. Then you could aim for unity gain (input=output level) or 
a constant boost between input and output. Note that the differences are 
sometimes what you want (think of a boost-for-solo patch). This is just 
the tip of the iceberg, as there are many other factors like eq on your 
guitar, playing style etc. Zoom claims that internal processing is 
32-bit which should give enough headroom, so I wouldn't worry about 
'optimal' signal/noise ratio.
In general getting consistent levels in a multi-fx is a bit of a 
challenge. If you want to keep it simple - use the patch level to adjust 
the volume (per patch).

Hope this helps,
Michał
