There was a request for 4ms Tremulues Lune with two LFO's but couldn't find a schematic for it. So we're stuck with the normal version. But for this layout I've incorporated an input buffer found in their "Luna" project. Schematic is aviable HERE as well different ways to wire up the rate LED and the bypass LED.
Cool! hard to catch up to the amount of layouts! awesome! any chance i can request the madbean tappy for the taplfo3 chip layout?
ReplyDeleteMany thanks!
ReplyDeleteLove 4ms stuff -- and thank you for the layout! I'm having a small issue with my build. the effect is working but I'm getting a horrible grounding hum that I can't seem to locate the source of. I haven't hooked up a foot switch bypass switch to it yet -- could that be the issue? Like I said -- the effect is working -- there's just a massive grounding hum drowning it out.
ReplyDeleteAny help would be awesome -- thank you!
DeleteDidn't realize this was unverified -- and am now determined to verify it. I Reversed the gain controls at M-19 (Now Gain 1) and N-19 (now gain 2-3) -- Gain now increases when you turn the pot clockwise.
DeleteHum persists -- as do I.
Tried swapping ICs around (TL022, LM358, NE5532, TL062, TL072) -- would suggest just going with 2 TL072s -- the circuit is louder -- and effect more pronounced and clearer. Humming has taken on weird oscillating modulation (no longer sounds like a grounding hum but rather kind of like a blanket of chorus effect over the tremolo effect). The modulated hum changes as you rotate the potentiometers to modulate the tremolo depth and rate etc.
DeleteWired up footswitch. No bypass signal from circuit. Sleep comes for us all. Will renew efforts on the 'morrow.
DeleteNo bypass signal wouldn't have anything to do with the layout. The bypass would be mechanical, through the 3PDT switch. Make sure you scrape in between the tracks on your strip board. I will often shine a flashlight through the board to see any obvious solder bridges but sometimes bridges are invisible.
DeleteOh absolutely -- I definitely messed something up with the footswitch wiring -- or the switch is busted -- and I was too tired to continue HAHA I'm confident the circuit works -- and this is definitely a me problem. Scraped the tracks -- re-flowed some shady looking points -- preformed a voodoo ritual -- and nada. I've made a cup of coffee -- stripped everything recoverable off it and am restarting.
DeleteThe saga continues... Wu Tang...
Completely rebuilt using all new parts (except I reused the ICs from the first buid) -- same grounding signal through it all. Scraped the hell out of the tracks to make sure -- still hums. Swapped out the ICs multiple times and with multiple different types as above (TL022, LM358, NE5532, TL062, TL072) -- still has this grounding hum. Thought it might be my guitar. Tried it with bass, dub siren, atari punk console and loops from Abelton -- hum is omnipresent. The crazy thing is that behind the hum (which is also modulated like the first build) I can clearly hear my original signal being effected. Not sure what to do next. I can't read schematics all that well -- but I don't see anything wrong with it. Yet this tremolo -- it both haunts and eludes me.
DeleteThat's a drag. I took a look at the schematic. No issues jumped out at me. I could've missed something. Unlikely that you made the same mistake twice but I often stare at my work for a long time before I spot a silly oversight. Keep us updated if you figure it out.
DeleteThanks for taking a look -- and I'll report back if I figure it out for sure! I'm not gonna give up -- but I find if I leave it be for a bit and come back with fresh eyes after a while I usually find the silly oversight. I built the Noise Swash -- the Temulus Lune shall not defeat me. But it is a worthy foe.
