I dunno what I'm doing Sunday, as the family wanna go out for a birthday meal, but I may try wriggle out of it.

If you put two on top of each other, as when you use both pickups on a 2-pup bass, the waves sit in line with each other and reinforce the sound. The sine wave of one starts on the up-ramp part of it's cycle, so does the other, both go up, win. Problems arise when you introduce any kind of delay, such as a signal goes through when heavily FX'd. Say your played note has a frequency of 100 hz. Each full wave takes 1/100 of a second (10 milliseconds or ms) to go from the start point, do an "up bump" of a sine wave, a "down bump", and back to where it started ready for the next wave. Each "bump" therefore takes 5 ms. The unprocessed signal goes from your bass into your amp. Then the signal goes to your FX chain, and picks up 5 ms delay from the processing. This means that your pure bass signal starts an up-bump the same time the processed signal starts a down-bump. If the signals were identical, you'd get zero sound at this point. Luckily for you, FX'ing the signal means they're not identical anymore but a significant amount of the signal strength is lost. Of course this only affects the 100hz notes if your FX chain has that much delay. The 300 hz notes will be affected less, and as frequencies get higher and higher it's harder to "line up" the phased and non-phased signals to cancel everything out. That's small consellation to us as bassists since it's the low frequencies we're generally interested in. The above phenomenon isn't solely linked to frequency-specific delay phase. If one of the speakers in a two-speaker cab is wired the wrong way round a similar effect happens. The same electrical signal from the power amp moves one speaker forward and the other backward. The result? Crap tinny sound. Same if the neck and bridge pickups in a bass are wired out of phase - or, even worse, the two coils in a single humbucking pickup. Thus endeth the physics talk![/quote] Kind of get it. Anything up near high E (7th fret of A) is quite quiet. Thought it might be a high fret or something? I will experiment with just running a straight signal again. Not more stereo rig for me, it seems. :-(
