unclej Posted June 10, 2005 Report Share Posted June 10, 2005 ok, i've got a buddy with a takemine flat top that wants to be able to plug in and wants volume and tone control and budget is a big issue. i'm an lr baggs dealer and i have an older RTS II in stock which doesn't have controls..it's an undersaddle ribbon transducer with an active end pin preamp. you can no longer buy the soundhole volume and tone control add on from baggs but their guy said he'd send me a diagram of how to add a regular volume pot..he did and it works fine. but i still need tone control. so here's what i've done so far..i've added a 10k volume pot (their suggestion) with three wires..removing a solder blob on the preamp board exposes two terminals which receive the wires from one outside lug and the inside lug on the pot. a ground wire goes to another spot on the preamp board and to the other outside lug of the pot. so far so good. volume works great. i then added in a tone pot runing a wire from the outside lug to the hot lug of the volume pot. i put a .005 cap on the center lug and a jumper from there to the ground on the volume pot. basically just like wiring up a single coil and in my head this should work but doesn't. i tried another 10k pot first with no luck and then a 250k pot and still no luck. any thoughts or suggestions? i've tried a couple of different value caps but nothing works. i'll drink a beer..ok, two beers in honor of the first one of you that can tell me why this doesn't work and if there's a way to make it work. __________________ Quote Link to comment Share on other sites More sharing options...
