Hmm- generally speaking, I agree with you. However, in terms of an electronic organ, I've heard that putting a facade in front of speakers helps to disperse the sound more naturally - like the sound of pipes going through the facade -- and the result is that the organ theoretically sounds more realistic. I don't know if this is true or not, but it certainly makes sense (kindof like putting speakers in a swell box will give a more natural sound than having a digital swell box because swell shades actually direct the sound physically in different directions based on how much they're open).I'm afraid not, anything you put in the way of sound will take away from it. It will never improve sound.
Personally, I don't really see the point to putting a facade of pipes on a toaster - if they don't speak. If you're going to spend that kind of money, why not buy a WORKING set of pipes and hook it up to your toaster?
Haha... organ facade... organ case... get it?As is often the case.
