Triple-Loop True Bypass Pedal

[modmod]

i'm just planning to make a box like this http://www.loop-master.com/catalog/product_info.php?products_id=50,just wonder if it's possible with only 3 x 3pdt switch ? anyone knows a right way to wire that ? thanks a lot

That's a box with 8 jacks and 3 switches. Just wire the send-return jacks as you would wire the effect in/out in a pedal.

my problem is how to enable only one channel a time,for example,if i switch to channel A,channel B,C will off automatically.any idea ?

Uh maybe.... The word 'relay' pops to mind but they're noisy when they switch, plus most relays eat power like crazy...

Actually the box you pointed to does not do A or B or C, but enables loops when selected regardless of the state of the other loops. So hit A, and you have loop A. Hit C and you have A and C. Hit A and you have only C. Etc. This is possible with 3DPDT's period.
If you want choosing one loop to automatically disable the other two (and choosing the loop that's already on causing the unit to neatly go into bypass) involves some electronics, electronic switching and  SPST momentary footswitches. Can't be done with 3PDT's I reckon.
