Another Tremulus problem...

[Barcode80]

so i built a tremulus lune. the LED is blinking with the rate like it should, so i'm pretty sure the LFO is working. however, when engaged the only signal i get is a HUGE oscillation/motorboating thing. the noise does tremolo though  any ideas? i've never seen this with a lune and i've searched to no avail...

okay, got that fixed. turns out that the tips of the in and out jacks were touching, causing mucho feedback and oscillation. all is good there.

so i have a great sounding two-knob tremolo, but i have a problem. i've taken out all the knobs except rate and depth. but when i adjust the depth knob, if i roll it down to about 3 or 4 (scale of 10) the signal dies, then when i get to about 2 the signal comes back loud again, but with no tremolo. i assume this has something to do with the knobs i jumpered, as i think probably that the knob is acting as a voltage divider for the LFO. am i way off? any ideas about this problem, or more efficient ways of eliminating all but those knobs?

i have the exact same problem, i think commonsound design their circuits so that they are efficient but will require a bit of tweaking by the user, you should probably try putting a resistor somewhere in series with the depth pot to stop it from going so low.

The depth shouldn't do that... it should go from full swing to unity gain.
What value are you using for the depth pot? ive had the same symptoms happen when ive accidentally used a 10k for depth (it should be 1k). And what kind of LED are you using next to the CdS cell? That's the thing to watch as you turn the depth down, it should never go to solid "off", it should always be either flashing or just "dim". If it goes dark then the LED isn't getting enough current which means either 1) use a brighter LED, a standard T1-3/4 super/ultra bright red LED (about 2V drop), or 2) apply more current by reducing the value of the depth pot and/or reducing the value of the 330 ohm resistor that goes from depth 1 to V+... [[or 3) the LFO circuit isn't working properly, but if your chassis-mounted LED flashes from bright to off then the LFO's probably working]]
