fleabag Posted March 20, 2017 Share Posted March 20, 2017 (edited) In case i cannot find one of these... Would this be of any use from Amazon ? Its dual latching, which i think is correct I've seen other dual footswitches but they appear to use a mono jack, and the TE has a stereo jack like this Amazon cheapie below ..

TrevorR Posted March 21, 2017 Share Posted March 21, 2017 If I recall, the TE is a couple of momentary switches rather than latching but I could be wrong. If they are latching then it should probably work. If not and they're momentary it shouldn't be too tricky a mod? Quote Link to comment Share on other sites More sharing options...
fleabag Posted March 21, 2017 Author Share Posted March 21, 2017 Hi Trev It wouldnt make sense for them to be momentary. Say you wanted to kick the graphic in mid song, you would have to keep your foot on the switch till you didnt need the graphic Same for if you wanted kick in the pre shape.

verb Posted March 21, 2017 Share Posted March 21, 2017 The switches are momentary, they just make a contact to negative to switch that part of the circuit. The foot switch has a wire from the pre shape switching circuit, a wire from the graphic switching circuit and a negative wire. Quote Link to comment Share on other sites More sharing options...
verb Posted March 21, 2017 Share Posted March 21, 2017 http://hpbimg.someinfos.de/diy/allgemein/_schematics/amp-schem/trace-elliot-MK-V.pdf The foot switch socket is in parallel with the front panel switches sw1 and sw2. Quote Link to comment Share on other sites More sharing options...
fleabag Posted March 22, 2017 Author Share Posted March 22, 2017 Thanks verb. I maybe misunderstanding things. I looked up the difference between momentary and latching and it still seems at odds with everything So if one wanted to kick the EQ in mid song, using a momentary switch, one would not have to keep their foot pressed on the footswitch ? One could kick the graphic in, take their foot off and the graphic would stay on ? I'm not really getting this, but then my knowledge of leccies is well below par Quote Link to comment Share on other sites More sharing options...
verb Posted March 22, 2017 Share Posted March 22, 2017 The signal does not pass through the switch, the switch controls the circuit that the signal passes through. So, no you do not have to hold the button down. Quote Link to comment Share on other sites More sharing options...
BigRedX Posted March 22, 2017 Share Posted March 22, 2017 Two Boss FS5U foot switches and a suitable cable - stereo to 2 x mono jacks - will do the job if you can't find a replacement TE switch. Quote Link to comment Share on other sites More sharing options...
TrevorR Posted March 22, 2017 Share Posted March 22, 2017 (edited) [size=3][font=Calibri][color=#000000]Yes, as Verb says, my recollection was that a contact on the footswitch was a signal for a relay in the amp to flip position rather than a hard open or closed circuit running from the amp to the footswitch and back again. [/color][color=#000000]If that makes sense. Hence using a momentary rather than latching switch.[/color][/font][/size] [size=3][font=Calibri][color=#000000]Different principle to say, a killswitch, where the audio signal runs through the switch itself.[/color][/font][/size] [size=3][font=Calibri][color=#000000]Happy to be proved wrong, of course.
