Power Scaling WORKS!
#5
Hi Guys

Glad you're happy, Josh.

I suspect the power level is substantially lower than 5W if you are judging based on the sweep of the Power Scale control? You don't hear a loudness decrease until you get to the power level you are actually using. As a reference, when the Power Scale control is set halfway, there is about one-tenth of the voltage and one-hundredth the power, so your 50W is putting out a half-watt tops.

To maintain the tone you have to set Power Scale and Drive Compensation (or your MV) about the same. Some players find this works down to a certain point and then they just use the Power Scale control, but it depends on the amp and speakers.

If you dial just the Power Scale control, the sound will get distorted just below the point where you hear the loudness reduce.

Have fun
