Trim Pot Wiring

[skypn]

May one wire a trim pot backwards? Signal in 3, with 1 &2 wired together. Wouldn't this just make it run "backwards"? I screwed up etching the pcb with the trim pot backwards. The circuit worked fine on the bread board with the pot the right way, and except for the pot, its the same. It sounds good when I just pluck a string for input, using my audio probe for output, but when I remove the probe, and try to play my Bass, it sounds like doo doo.
The circuit in question is a Bass Fuzz with a blender

One has wired them backwards too many times....don't ask me how I know.

Yes, trim pots are usually linear, so there shouldn't be anything weird about wiring it 'backwards'.  Other than needing to turn it the opposite way.

If the audio probe sounds fine after the trim pot, but not fine later in the circuit, I'd suspect something has gone wrong later?

Do you have a schematic we could look at?

Thx for the replies. I believe I found my problem. I had a couple cold solder joints
