'Power Scaling' lets you get a true 'Cranked Amp Sound' at VERY Low Volume Levels. When I first Experienced 'Power Scaling', I could not believe how good it was - Full Harmonics - Sustain a Mile Long - the Whole works, but at a Volume level you can 'Talk' over - it's Unreal. Simple to use, Just like a Normal Volume Control, as you 'Dial Down the Power' - The Volume Drops but the Tone is Maintained. 'Power Scaling' Allows the Output Power of the Amplifier to be Varied from 100% down to Less than 1% of the Full Rating - Fully Maintaining the Warm Tone and Natural Harmonics of the Output Valves. Sustain is Increased slightly when the 'Power Scaling' is active and 'Pinch' Harmonics seem to leap from the Fretboard on just about any Guitar. Some of the 'Side' Benefits of 'Power Scaling' are - Waste Heat from the Output Stage is Dramatically reduced as the Power is Dialled down, Greatly Extending Valve Life - Because of the Extra Filtering used in the Circuit, Background 'Hiss' is Gone - Power Consumption is also Reduced, this will extend the life of all the Components in the Amplifier.

When the 'Power Scale' Control is set to Full Power (not being Used) it has NO Effect on the Amp 'AT ALL'. The Amp will work the Same as if  'Power Scaling' was Never Fitted.

At Bedroom Volume you can TRULY obtain the Full, Sweet Valve Harmonic Overdrive Sound that you have probably always been looking for.
