How about a toggle switch to apply the LFO wobble to pin 6 as well as pin 2?
And what about having a trimmer + resistor in place of the 100K resistor to ground on the output? Could be like a "level" control of sorts to help match unity volume. Unless you already have output volume control via op amp in the works for the Elite.
I tried it. Didn't really do much. Gotta build a second LFO for it to modulate at different speeds, then you would notice a difference.
Also, I just used a 100k volume pot and started it out on high, like 100k to ground. I ended up having to turn it down a hair (to probably about 75k) to hit unity. I'm also using a bass to test this (since that's what I'm building it for), and noticed the B and E strings don't get as much of the effect as A and higher.
I noticed, though, that my 500k pot only had about 1/8 turn as usable range... after I dropped the 33k. With the 33k in place, I was getting no wobbling. I triple checked everything, so not sure why it does this. Also, my 100k has only about 1/4 usable area. I'm done with it for the night, but if anyone has any suggestions, I'll try them out tomorrow.
Edit to add: I'm using TL072. Could this be part of it? All I have on hand at the moment is TL072's & 4's, 741's, TL082's, and LM324's.
