'LIGHTWAH'

[deadastronaut]

yep sine is fine...as above... i'm trying to get it slower though at the moment..


ahh so you never got it going then...shame!..the theory looks good to me...

is that the colorsound inductorless wah...looks a lot like it...?

yes, the same, but with a better lfo, I think.

in the future I'll make it.

i suspect if i want it slower to change cap values...i'll tinker with it. thanks man...(craplins only had 1 ic... ..they live up to their nickname)...

Yes, all three. Or you can probably change the 100k and 150k resistors too.. As long as they keep a 1:1.5 ratio
The schem I posted is set up for a vibrato. If you raise the caps it will go slower, but the fastest speed will also be slower. So you have to find what suits your application the best.

@arnoud. . gotcha!.so its a trade off ,  with fast v slow....

..i'll try that today!...in between doing stuff!...its me and my missus 16th anniversary today, so ive got to cook, clean, scrub up, and wrap stuff,
then light candles, eat, drink lots of wine, and .....breadboard in between.... i'll try some 470nf's....

[~arph]

I believe I used 470nF too in some pedal... don't let the breadboard get in the way!

ha ha...i wont.. yeah just tried 470nf's ideal i think...still fast too....

[deadastronaut]

great news!...

breaded the colorsound wah again....not the morley..

linked it up to the lfo/sine...yep!..works great and NO ticking....excellent...

the wah and sine lfo are on seperate breadoards at the moment....i'll join em up tomorrow and see how it behaves...

love it...

hi guys, everything is fine and dandy, but there is a big level drop on the wah..compared to bypassed...

am going  to need a buffer/boost in there...any recommendations..?

ive been using a 386 just to lift the level,for now, but i'd rather a nicer smaller buffer(recovery stage)  on the output...

[bluesman1218]

First of all, I hope you and the missus had an awesome anniversary, CONGRATS! Sweet clips, Rob, Can't wait to see the finished product, layout & pcb for etching! I know your enclosure looks mighty fine already.

[deadastronaut]

cheers man, yeah we had a great time...hic!...plenty of wine..

got to sort this clean boost out...otherwise it sounds great..

this is the wah i ended up using..



any ideas on an ideal clean boost on the  out?....

[ppaappoo]

Try a bigger value for the 10k resistor between the 9v and the transistor.

[deadastronaut]

cheers pappoo... i'll try it now!..


edit...

tried it with my resistor sub box...no joy...the bypass is much louder than the wah,..

[artifus]

pot and multimeter to the rescue!



mmmmm... pot...

[deadastronaut]

nope!.....

tried it from the 10nf...better level..but thin...

[ppaappoo]

increasing the 47k resistor to ground at the end?

[deadastronaut]

mmm bit better, but not up there yet!...

edit:

dropped the 100k at the end...to a 2.2k..much better level wise...i'll try a fatter cap with it too..

[ppaappoo]

mmm bit better, but not up there yet!...

The 100k and 47k acts like a 147k vol control at 9 o'clock. Try with a 100k resistor an then you have a 200k vol control at 12 o'clock to be able to use a 1M resistor.

cheers pappoo....

i'll have a read up on it...

been busy today, my mate bought a guitar off ebay, and the kid he bought it off, just put it in a gig bag...got delivered with the head snapped off the neck...

it was a clean-ish break...my mate was in bits  ...so was his guitar..  ...so ive been repairing that...it'll be ok.....anyway..never buy guitars without hard cases eh!...

i did warn him...but do people listen?...

back to the wah...now...



edit:
tried a few of those suggestions in the thread...cheers pappooo...

hmmm attacked it from the in...and the out..in the end..trying to get it right without it distorting..but still having a bit of thickness to it too...

going to whack a 3dpt toggle i got ages ago on my breadboard so i can hear true bypass instantly, without @#$%ing around with wires in and out...

should have done it ages ago..

[deadastronaut]

right. the best settings i could get/like are, and levels seem ok...
edit..

100k
47nf
=========\=======>out.
                   /
                   \
                    /   100k
                    \
                    \/

lifted the volume nice.....in fact a 470nf with the 100k is nice for a full but clean sound......ive yet to try it with distortion...

i tried messing with the input, but it broke up too easy...so output mods it is...
