" goal is to achieve the same tone as our loud sound but at a much lower volume." Secondly what is "Power Scaling" e.t.c, why use it and how does it work? Well, take these explanations from the London Power website Voltage scaling is said to allow you to maintain "that" tone you get from running a tube amp flat out with all the volume controls turned up to the max but also allow you to maintain your relationships with neighbours/children and/or spouses without having to resort to playing your guitar in an underground bunker.īest of all this technology is compatible with 99% of amps below 50W!įirstly SAFETY! If you're not confident working with the voltages associated with tube amplifiers don't even bother with this, you WILL end up toast. Both are methods which allow you to scale back the voltages within your amplifier to attenuate the overall volume without having to use a cumbersome purpose built attenuator between the amplifier's output transformer and speaker or rely on a simple "Master Volume" control which dials out the all important power tube clipping. Power Scaling (a London Power trademark) and VVR, which stands for Variable Voltage Regulator, (Dana Hall of Hall Amplification's version of Power Scaling) are currently two of the hottest topic's in the Guitar Amp world.
