Hi all Smile

Phobos kindly helped me out a while back for a circuit to switch 6 diy FX (stompboxes) in different permutations , i got the veroboard cobbled together earlier this year along with the FX pcbs that i bought from DeadAstronautFX pedals & FuzzDog pedals Smile .

I'm now at the stage of a test panel template design which i've done this weekend , i will be using an aluminium panel size of 600mm by 200mm for the finished unit .

Using a CD4053 and a 12pole / 3 position rotary switch and signal buffer/splitter , phobos's circuit gives me the preset configurations i'll be using.

setting 1 - No1 input buffer/split sent to 3 FX chains which are.. chorus > filter. / chorus > delay. / chorus > reverb.

setting 2 - No1 input to chorus > filter.
No2 input to chorus > delay.
No3 input to chorus > reverb.

setting 3 - No1 input buffer /split sent to 2 FX chains which are .. chorus > chorus > chorus. / filter > delay > reverb.

the outputs from the setting 1 & 3 chains are summed at a wee mixer , on setting 2 the chains have a separate output socket each .

here is the test layout which i will print off on paper to see if there are any dial / switch measurement clashes etc Smile

the right hand side is an area for 2 standard fx stomp boxes there will be circuits for level shifting to and from modular levels to use my pedal collection on the modular Smile
