One of the points you raise (Aron) is the relative degree of compression in the input signal.
I think any test CD with simulated input signals should probably have multiple versions of the same signal with varying degrees of dynamics. I think much of how distortion units respond (especially battery-powered ones) has to do with recovering from sudden demands on the power supply, slew rates (if IC's are used - e.g., the RAT), and the like. One need only plug a compressor ahead of a distortion unit to hear how variations in dynamics alter the way the device responds to pick attack. Insomuch as pickups themselves vary not only in output level and timbre, but dynamic responsiveness, it seems only natural to have a sense of how effects devices respond to such variations by including them in a test CD.
Now that I think about it, don't any pickup companies like Seymour Duncan produce sampler CD's of their different pickups? Would these suffice for a test signal source until the ideal one comes along?

Then again, another very useful thing to have is one full AC cycle of a pickup output synthetically recreated endlessly (OK, five minutes or so) so that you can simply run static-level tests as well. Kind of a lifelike signal generator. Probably for several different pickups.
There are tests where what you want is a steady tone.

Sure, we can do that. You can take a recorded note and cut out a single cycle with Goldwave or Cool Edit and paste it back in multiple times to create a continuous output of any length desired.
In fact, those wav editors can loop a sample so that it will play endlessly (or until your wife screams at you, anyway).
You could do it with single coils, humbuckers, piezos, etc...

So how's the test CD going?
