I need a 3-button footswitch where one switch shorts the tip of a TRS phono plug, one switch shorts the ring and one cancels the shorting. I want to step on any switch and get the needed response regardless of the last switch pressed. The amp I have can be switched through 3 channels this way. When the tip of the TRS is shorted it will switch to gain. When the ring is shorted it will switch to clean and with no shorting it will return to burn or high gain.
Does anyone have a schematic? Is there anything like this available?
One switch shorts tip and clears the short on ring. One switch shorts ring and clears short on tip and the third switch clears both ring and tip?
In addition, it would be nice to have led lights.
Please let me know if you can help, cheers.
