As a spin off from a conversation in another thread, I realised that have never really considered how a modeller manufacturer determines whether a model is a true and fair reflection of the amp, cab and mic combination they are attempting to model. So , without giving away any trade secrets, how is it done? Do you look at: - the final result - i.e. does the Fender Deluxe model sound the same as a mic'd Fender Deluxe? - each element individually - ie, does the preamp produce the same output based on a certain input, same for the power amp, the cab, the mic etc - both of these - something else?
