Hello all!
First post here! I have plenty of experience with soldering and I can build off of layouts, but I'm still fairly green with the diy audio circuit, 3PDT switching, signal path, etc. So I get a bit confused when trying to mod/alter even a simple layout like this. I'm trying to put together a true bypass feedback looper pedal and add a few features. I would like to add in a momentary switch (normally closed/off) for the feedback section, where the feedback is switched on when pressed. I would also like to shine the LED when the momentary switch is engaged. I'm trying to use a basic, red button SPST type momentary switch FWIW, and I cannot seem to find the right place to drop it in and operate as desired. The schem/diagram I'm working from is the old Beavis looper http://68.media.tumblr.com/tumblr_lfwjj510Ya1qemwmy.gif
I would like to keep the 3PDT, on/off (SPST) feedback circuit toggle, and 500k feedback pot. I know I can just do away with the toggle and put the momentary in it's place, but that's not what I want ideally. Momentary max feedback seems like a cool function, but I don't know if it's doable with the pot, or more so, safe on the amp and ears?
I would also like to add a level pot after the 500k feedback pot, but I'm not too sure where to place it either by looking at the diagram. Signal path, ya know. I haven't tried it physically yet. Basically, I'd just like to be able to max (or close) the feedback function and still be able to control the output level.
Also, I've also thought about it having a momentary kill or stutter button at the end of the feedback section, so if anyone has an idea for that, that would be sweet. It's really not that important overall though. Any help/ideas with this, and/or knowledge to help me gain a better understanding of this stuff, would be awesome and greatly appreciated. Thanks!
