I can't seem to get the effects loop to work the way i want it to. A project requires me to use a delay effect with my upright. Full circle -> AI Clarus -> RE bass 12. I connect the send jack to the delay pedal input, the return jack to the delay pedal output. With the delay engaged, i get my a signal + delay through the speaker, when i turn off the delay, i get no signal anymore, silence. Is this the normal behaviour of the effects loop? I thought that i could just insert the delay, keep my signal chain from piezo to preamp as clean as possible and be done with it. Any insight is greatly appreciated.
