That setting worked well with the JMP 50 2x12 I had, with my (USA) strat.
For humbuckers, a little less pre amp gain, say 5-6. The JMP50 2x12 I had
was a 1977 cracker. Only sold it due to the weight, getting older you see.
Replaced with the JMP100 watt head 2203 (later renamed JCM800 before they
introduced the split channel 800s)
