'LIGHTWAH'

[Dork]

Thanks rob! Much appreciated!

I´ll let you know when "the Deadastronauts Box of Doom" is finished! 

Cheers,
Chris

[deadastronaut]

cool. look forward to it chris...

meanwhile i'll keep floating around in space.......


edit:  tip:  use miniature/low profile electro's for a better fit into a 1590b..

I almost finished my build. I have to design an enclosure but the circuits is done. Everything works fine!! 
Rob, just wow. It sounds great, unfortunately my spare time is limited today, so I´ll test it in the next few days.

But I already think, I like it more than my Snow white auto Wah!


Great job, mate!

[deadastronaut]

great!...glad it works ok for ya!..

the wah sweep is nice on it isn't it, , i tamed the hissy screechy highs deliberately, i love it too....cool man,

look forward to seeing it boxed too...

[Dork]

Hi Robert!

Yesterday I had some time to try the Lightwah. I still think its very nice, but the LFO Wah sounds a bit too dark for me. Do you have an idea what I should change to get a bit more treble?
I haven´t boxed it yet, I plan to make a big enclosure with 3-4 fx in it, and I wait for some IC´s to finish my small clone chorus.

Thanks,
Chris

try lowering the values of  c5 , c6 and c7....

http://www.morleypedals.com/clwes.pdf

here is the wah section schemo, ^  note the 5pf instead of 47pf.(c5)....in the 'T' section...

you may want to socket them if you want to try different values to your taste....

[Dork]

Thanks, I try it in the next few days. Good Idea to socket ´em.
I already used a socked for C6 (I had no 6,8nF)!

I let you know which values work best for me!

[deadastronaut]

cool, you could always have the caps switchable too...bright/normal etc...

i really love reading this thread.. And i really like the sound of your lightwah sir rob!!
.
I have some question sir!
Can i use 100k lin instead of 100k log for volume pot?
.
In your pdf there you can see board 1 so is there any 2nd board?  Sorry im a beginner in this project and dont have enough knowledge for this thing.. Here in the philippines we cant find any log pots and 3pdt switch ordering them on internet cost much money a lot.. I purchased all but not the log pot..

[deadastronaut]

hi gyjelgaven

if you really can't get a log pot then that will have to do...it will work as a volume, but just be a different feel...but yep it''ll work ok..

2nd pcb?.....nope!... there is only 1 pcb ok.

just remember i updated the pdf so C8 is a 10uf....ok all the best rob.

[gyjelgaven]

thanks for reply sir rob! I just finished the lightwah but only the lfo wah is working ..there is no wah sound from manual wah and i dont know how to fix this issue.?. the volume pot and 2 other pot are working fine exept for depth pot i cant see or hear anything changes turning this pot..  By the way sir do you have a pcb layout only for manual wah using ldr and led/ldr like the sound like yours.. I really like your wah sound.. .

[artifus]

i'm sure rob'll be back with some answers and i can't be sure but at a guess it sounds like a short so maybe check your connections.

just a thought: in long project threads like this is it possible to edit the first post to point to verified schemes and layouts?

also, @rob: i stumbled upon this recently and thought of you: http://www.astronautsuicides.com/ (use the scroll wheel to, erm..., scroll!)

sir rob?..   lol...

anyway, your wah and lfo are working so thats a good sign...

the depth will only work on the lfo auto wah setting ok...

have you wired the switch up properly?
is your manual wah led  lighting up and fading with light/dark?...

go over your wiring connections..its probably something simple..i know its a pain but we all @#$% up sometiimes in the anxiety to get things going......well i do..


@artfus:  that's me chiiling out....

as for your post question, dunno, i know you can click on a certain post and copy the link so it goes straight there....otherwise no idea!..

i think i have to etch and drill  a new one. Lots of headache from that perfboard. By the way does anyone have a pcb layout for morley wah using tlo71 or tlo72 with ldr wah controls.

ahhh i see , you were on perf...

i haven't a pcb layout for the wah/ldr only...sorry..

if i have time i'll knock one up ok...

[deadastronaut]

ok, i had a go at doing a LIGHTWAH without the lfo , check in my gallery for the pdf's.. ok!..unverified, but looks ok to me..

you could also add a pot with the led/ldr combo to have a c-o-c-k-e-d wah setting too..toggled of course..

as luck would have it a mate wants to add one of these to his project...if you verify it let us know... .

i tried this circuit> 4shared.com/document/l5rKXWrj/Wah_Wah_-_Morley_Classic_Wah_-.html a classic morley wah in a breadboard but instead of using a 100kpot i used an ldr. The sound was like a volume pedal so i decided to replace .068 by .0068 and thats it! It sounds like your wah huwahh!! My question is how to obtain huwahisshh sound like using a 100kpot  by using ldr. Ive also add a sense pot like yours.. 2nd question how to light led to be more lighter?

[deadastronaut]

100k pot in a ldr?....sorry i don't understand that...

i used superbright blue leds...at the time. lights up fine...

[gyjelgaven]

lol! Sorry haha.. I mean using a 100k pot you can obtain huwahisshh sound..while an ldr you can only obtain  huwahh.!   And also i tried my phone camera flashes to ldr and it gives more wah than superbright led. I was using superbright led white and blue..

[squigglefunk]

light wah > echobase delay in one box. I have hooked up the wah/lfo switch to the second stomp from the right and I have rigged it up so the photoeye also can be used to control the LFO speed.

thanks for this excellent sounding effect deadastronaut!

One Q so far, I have a tiny bit of LFO noise...  I tried looking through the thread but didn't see anything

is there any suggestions on how to eliminate it?

Thanks so much!
