I used the Zoom software on my PC to copy the patches I'm using (blues) to unused slots. That way I can modify them without mucking with the originals.
Even with the volume up at 100% this patch is 8DB quieter than the next one. (as measured on my DB meter)
For the moment, I'll just have to avoid all the "quiet" patches until I get this new pedal figured out.
Thanks for all your answers!
