To increase the output level I'd recommend to increase R17 (is now 15k). To
increase the input level causing clipping/overdrive at higher input levels
I'd recommend to increase R12 (is now 47k) or to lower R13 (is now 10k).

Best wishes

P.S. These statements are valid only for the new version of the A-131 (not
for the CEM based old version).
