I want to build a switcher/router

[longi]

Hi all,
i'm new here, and I want to build a simple switcher/router to switch between my modeler in the effects loop of my amp using the 2 cable method for when i'm using it for efffects only, and then be able to switch to the modeler when I want to use it as a full time modeler for it's lower gain sounds that my high gain amp struggles with. The modeler would be working all the time either as a modeler or for effects only. It should be a reasonably straight forward build but i'm not sure if the design is closer to a looper or an A/B type pedal with a bit of modification. Would I also need to build in an anti pop circuit too?

welcome

The search tool should bring up a lot of these...

  Either overdesign or draw out the minimum which allows the features you want.  
 DPDT [2 poles, each of these separate switch pole has 2 throws]. Said differently, each P channels signal to one side or the other [through one of it's throws at a time.
 DPDT shows the basic true bypass topology, the switches can remain mechanical but have electronic relay drivers, or can be electronic [ie the signal passes through an active switching device]. Probably worth investigating these options if 'remote' switching is desired as it may eliminate long signal runs, reduce enclosure size and simplify usage/increase reliability by eliminating patch cables and messes...in the long run.
 3PDT [three separate poles, each having two throws/for adding LED or __.
  Multipole switches like these switch the 2 [or more] separate poles simultaneously, mechanically connected but electronically insulated from the other poles. The two throws per pole are also insulated.
 The 'patch cable working' allowed easily re-routing and effect swapping to find results which helped me determine effects order.
 I would prefer the features of electronic switching but dread the efforts that would be [and might be] involved in implimenting it, having considered a rebuild of all new circuit boards so my old pedalboard could remain intact/functional until the laying out / building / debugging process could be finished.

Thanks for the replies guys I didn't quite have enough time to finish off my post this morning so you only got a half of it! Anyway, I drew it out earlier so i'm pretty sure I know what to do (I'm an electrician by trade but do more electronics these days although i'm self taught and still learning the electronics side!!) I'm looking at some point to being able to control it in the future with the Voodoo Lab Control Switcher which will need a powered relay and some other "sorting." But for now i'm just looking at getting it up and running. What I want to do is this, the guitar cable from the amp will go into the switcher via the switch and out through to a send jack, the modeler will run from the amp send jack and into the switcher via the other set of switch contacts, then from there out of a second send jack and into the modeler's input jack. The switch will then just switch between using the modeler purely for effects only, no amp models, then switched so the modeler is used as a modeler/multifx directly into the amps return socket bypassing the amps preamp channels completely. Ultimately, everything will eventually be controlled by my modeler and Voodoo labs control switcher. Easy peasey! So the question is, will it, or is it likely to make a popping sound when switched? What I intend on doing is buying a looper/switcher kit and modifying the way it's wired/switched as there doesn't seem to be anything like it on the market for this purpose.
