Is OPR (Output Power Reduction) Really any Good?
A. I have tried all of the Alternatives, they all work to some degree but ‘OPR’ (Power Scaling) is The Business, It works Brilliantly and is Extremely Reliable. Almost all Valve Amps Sound Great when they are ‘Cranked’, but how often can you Crank your Amp without somebody complaining – ‘It’s Too LOUD!!’ – With ‘OPR’ you can Crank your Amp every time you use it – Then just turn the ‘OPR’ Control Down to an Acceptable Volume – The Tone will stay the same. ‘OPR’ is the BEST and nothing else can touch it!
