Wind yer own

A place to discuss all the cool pedals we love to torture our amps with.

Yes they did and I prefer this value. I have an old crybaby that is a Clyde McCoy in disguise and it has the 100k resistor.

Yeah I want to try the 100k plus true bypass though it might be necessary to lower the 68K series input resistor value for an increase in volume.
I know some aficionados would poo poo this :roll: but I might try it on one of the old Vox wahs as it’s not evasive and the original Arrow switch is long gone anyhow.

Which variant of crybaby?

My crybaby looks like this.

And has a Clyde board like this.

I put a true bypass in it as well.

Ah very nice 8) with those components essentially it is a Clyde.

Yes, it's a Clyde in disguise. 8)

ooh I like the 100k also. Sort of (how would you describe this?) "wider" vs. 33k?

It gives you more high end so maybe a wide range.

Board from GP electronics is in transit; think I have most of the other bits already.
I might try that pot in place of the 33K, see what sounds good….

FWIW I did true bypass my old wah & changed the 68K to 47K, sounds good to me..

Stu, a member here has quite a lot of experience with playing with these (he fixed my old Crybaby for me) wonder if he might chip in.

As if by magic...

The 100K was only used with a specific variant of the halo inductor, which had a much higher DC resistance than the more common ones. They used a 100K to offset the reduction in Q from the higher DCR.

Hi Stu,

Ah so the 100K wasn’t a random value thrown in, I’ll probably try both or a trim pot in my project pedal just for the learning experience and some of the other tweaks.
Not sure how it will compare to my old V846’s but it’ll be fun trying.

Thanks for the info!

No, not random. Later, with the V846s there was a period where they substituted some values e.g. 430R, 910R, 1K3, 9K1, 36K, 62K and 430K.

inneresting (thanks stu!). So higher DCR = thinner gauge?

FWIW I measured about 5(?) black ones which appear to be more recent Dunlop (had "D" marking) and they were all on the high side (my understanding is that the typical tolerances for inductors isn't very tight, so wondered if from Dunlop's perspective it made more sense to be off higher than lower (seems thinner and maybe "weaker" sounding)).

Also, I've opened up a red Dunlop Fasel (bit higher than 500mH), and the windings look sloppily wound (wonder if that is doing anything). Some grey stuff inside (glue?) as well.

Brian here ya go

I wonder if they adjusted the resistor as an engineering tweak to make it look good on paper or did someone actually listen to the thing?
