Hello fellow boogiers.
Nice to join this wonderful forum!

Looking at the fx loop schematic I noticed something strange.
When the fx loop rotary assign switch is at on position it turns on the optocoupler.
This in turn shuts voltage supply to J175S & J175R.
thus mutes the fx loop send and return jacks.
Isn't it suppose to be the other way around?
Am i missing something?
Is this a schematic error? :shock:


edit: removed boring and agonizing life story
 
Well i feel dumb :oops:
unlike regular transistor a JFET resistance grows when voltage applied to the gate.
No schematic error.
