Well I put the 2.0 chip back into my Pod.
The 2.0s output is substantially higher than the 2.3.
This is important for me since I have to run it through a Passive four in two out mixer, the old Teac four channel mixdown switch box, that I used to use with my Teac 3440 reel to reel. This box drops the volume, and since it's passive, there is no volume boost.
But the real clincher for me, was that I had a user preset that I really liked for my acoustic electric, using the 2.0 chip, and I remembered the settings. Also had a recording I had made as a reference.
Well when I put in the 2.3 chip, as hard as I tried I could not get this sound back, and worse I couldn't get it to sound as good.
Oh well, out with the new, and in with the old!!
