i've recently become bored and i'm considering building my own pedal board... by this i mean the "be-all end-all" for my ever growing needs.
I've come up with a design that will allow for all my current needs (few) and future needs (could be many) and included everything from power supply (9-18v), switchable loops, stereo/mono out w/A-B-Y, DI output, etc. setup in a custom package, most likely aluminum w/flight case...
most of it's pretty straight forward wiring, which makes fairly good sense to me, i'm a logical thinker (most of the time). but i've been left with some simple (sorta) questions. the first, and most obvious, where this is effectively a giant looping pedal/A-B-Y box, can i safely common-ground the whole instrument signal chain? or more importantly, is there any other way to do it? am i imagining a problem where one doesn't exist?
second on my list of questions is based on signal loss... with the potential for 20+ ft of lead on either side of the board, and many more feet of internal wiring, should i be concerned about losing the strength of my instrument signal? would a simple line-booster take care of that? I've also heard of using some sort of "Input buffer", though i'm not sure what's meant by that, or if it even applies to this situation.
before the inevitable... I do know that there are numerous commercial products which do much more or come pre-assembled and test, but i'm sure most will understand the enjoyment of a job well done, having something that's right for them, and the chance to save some $$...
please, don't feel the need to hold back any additional advice or opinions, as well if anyone has a known source for custom-fab'd enclosures...
