I'm making a talkbox for which I need three connections to my guitar amplifier:
- amplified signal
- connection back to internal speaker of the amplifier (Vox AC15).
(see diagram) For the connection between amp and talkbox I would preferably have just one cable with two mono jacks (TS) at the amp and at the other end, a stereo jack (TRS) to plug into the talkbox. In this way the three connections mentioned earlier are all bundled into one cable. The cable I'm thinking of would be similar to this, but suitable for a speaker level:
I can't actually find on the internet and have never heard of stereo speaker cable . Does such a thing exist? Is there any electrical or safety reason why stereo cable is not apparently available?
Generally you would only connect one speaker to one output, not two to the same output jack. Is this the reason?
I could alternatively use two speaker cables but it would be tidier/more convenient to use a cable with three cores.
