i am not at all opposed to using an IC switch, though i would have to rig up a point-to point board or something (a couple of years ago i could have etched a PCB, but i don't have access to that at school anymore)
would it be at all possible to ask you to draw up a simple circuit using one of those IC's?
They are very very easy to figure out how to use. Take a look at the datasheets. Essentially, you have 4 SPST's, each controlled by a pin. Imagine having a (essentially) infinite number of SPSTs, all controlled by a single SPDT. With the SPDT up, some SPST's are on, others are off, with it down, the SPST's all switch states. This is what you can do with electronic switching. Because you can take two SPST's and make them share some input with two outputs and make their control pins opposite, you basically have an SPDT. Since you can make as many poles as you need, you can have a 1000PDT if you really need it. This is kind of what we need here. We need a switch with four poles. When the control switch is up, the input is connected to flanger input, the flanger output is connected to delay input. The FX loop is wired straight through. With the control switch down, the input is connected straight to the delay input, and the FX send is at flanger in, FX return is at flanger out. We essentially have a 4pdt here-5pdt if you want an LED to top it all off. Some things to consider with the 4066 switching is that you should have a .1uf capacitor from the power supplies of all of them straight to ground. The simplest control switch would be a DPDT, with one set of controls on one pole, and the other on the other pole, with throws being opposites-V+ and ground. If you use pullup resistors, you can just have an SPDT with the center lug being ground, top and bottom lugs being the control's. You can also use a spare 4066 switch and use an SPDT, but then you are getting a little complex and mildly silly!
Some notes on 4066 switching, with some unnecessary (in my mind) logic on the control:http://www.geocities.com/thetonegod/swi ... tches.html
