i've wanted to make a feedback looper without true bypass channel. soldered this together but must've made a mistake. it works a bit as dry/wet mixer but not as a feedback looper... anyone an idea why?

Hello

I'm really new to DIY-Stompbox making... I've build a couple of OD-pedals but I'm really interested in building myself a Talkbox-in-Stompbox. I've been reading up on the topic "Help with talkbox internal amp?" but I still have questions about making a stompbox model.

the out of the Ruby amp mentioned in the other topic goes to the speaker-in. Is it then simply a matter of connecting the speaker out with the out-jack of a stompbox? I guess that one should go to ground...

And then there is the plastic tube. how en where should it be connected to the speaker?

Thx
