simwells Posted March 16, 2009 Share Posted March 16, 2009 (edited) Hi Anyone know how I would wire up a switching box with effects loop that would switch between two outputs and inputs so the switch would swap between; Input A > Output A and Input B > Output B Basically to use my effects chain with two different instruments and two different amps. In my head this would basically mean having two switches, A in/B in to loop out then loop in to A out/B out. It's just controlling it by one switch I'm not sure of.

bobbass4k Posted March 17, 2009 Share Posted March 17, 2009 Some very helpful stuff [url="http://basschat.co.uk/index.php?showtopic=40389"]here[/url] Quote Link to comment Share on other sites More sharing options...
Silent Fly Posted March 17, 2009 Share Posted March 17, 2009 I draw a quick schematics for you. If I had to build it would use a 4PDT switch. If you can't find it, the 3PDT switch schematics [i]should[/i] work. I hope this helps. [attachment=22190:AB_fx_AB_switch.gif] Quote Link to comment Share on other sites More sharing options...
simwells Posted March 17, 2009 Author Share Posted March 17, 2009 That's really helpful, only thing I'm not entirely sure of is how to wire up the one with the 4PDT switch, can understand the 3PDT one, just struggling to understand how the 4PDT switch fits in. Sorry my knowledge of electronics is pretty basic. Quote Link to comment Share on other sites More sharing options...

Sorry my knowledge of electronics is pretty basic.[/quote] Unfortunately, there is no easy answer 3PDT switches are more or less all the same, 4PDT switches can be different one from the other. If you go [url="http://www.little-black-box.co.uk/components/4pdt-super-bypass-footswitch/prod_26.html"]here[/url] you can see [url="http://www.little-black-box.co.uk/images/uploads/switches/4pdt-wiring.gif"]an example[/url]. I forgot... if you buy [url="http://www.maplin.co.uk/Module.aspx?ModuleNo=1263"]switched jacks[/url] for send/return you can use the box to switch bass/amp even if you don't have anything connected in the fx-loop. Please feel free to send me a PM if you need more details. Edited March 17, 2009 by Silent Fly Quote Link to comment Share on other sites More sharing options...
