Hey there, please help me out with this. So I've been kinda fed up with reaching over and pressing the button on the timer, esp when burning. I have a footswitch, but it is a proprietary 3 pronged jack for a LPL ET 400 timer that is broken. I bought a ~$6 keyboard foot switch that has a 1/4" adapter, but I just found out today that it doesnt fit the Gralab 451 I have. I dont have the manual for it, but it seems the input would be a 3.5mm mono plug. Not sure though. Would this keyboard pedal work if I found a 1/4" to 3.5mm mono adapter? or a more common stereo adapter? Does anyone have one and can confirm that it is a 3.5mm jack? thanks!
