Starter question about jack and SPDT wiring
« on: March 08, 2010, 08:40:49 PM »
Well, hello everyone, I'm a newcomer here and this is my first post.
I came here because I need a little help with my talkbox wiring. What I made for the talkbox was a simple 10W amplifier (a TDA2003) in a box, wired to a speaker and alternatively to a mono out jack for bypassing the effect (and sending the signal to a guitar amp). The thing is... I don't get any sound out of the speaker and not even INTO the circuit, so I guess I screwed up the ground connections...
Here's what I did with the wiring:

Can you tell me what have I done wrong? Couldn't found any data on the net, since all pedal effects use the same output for bypassing and I need to different outputs.

Your wiring is fine, check that the TDA works hooked to the speaker.
