Postscript. After a quick search, I found this useful site. It has schematics for the ‘original’ and ‘reissue’ Dunlop pedal. The latter shows how the SPDT (single pole, double throw) switch can be replaced by a DPDT (Double yadda yadda) to effect (terrible pun 😳 ) a true bypass.

I can’t speak for how well it works, but I do wonder why it wasn’t a factory fit on the initial reissue. The schematic for the Vox is also there. Not that I’m an expert in hieroglyphics, but I don’t see a lot of radical difference from the Dunlop:

The parts # is RS1388 and the web page is http://www.bgmicro.com/lmad2.asp (I’ve fixed my c+p problem 🙂 , but now have runtime debug error every time I go to a new guitarsite page 😥 . Win some, lose some.)

My exp with the JD is limited to a few months back in the 70s, and the lead guitarist who used it fairly extensively in my 90s band. So, I had a look at the HC reviews. OK, in use I guess the treble was a bit accentuated, but that was just part of the pedal’s sound to me. Other pedals (eg, the Morley) don’t have it, but then it’s not a Dunlop. It depends on what you want.

The other issue is the noise and treble-sucking when not in use, as there is no ‘true’ bypass. That can be got round; have look at sites such as geofex and schematic-heaven, but being (or knowing) a good solder-monkey helps.BTW, the Crybaby is definitely not digital. Digital FX are a relatively new strain from the late 80s onward. The Crybaby is as analogue as a Grandfather Clock.

hi does anyone know the part number for the wah pot that you can buy from BG micro that someone said was only $6.95 there.
also is it better to buy a cheap dunlap wah & mod it or just but a Vox clyde Mcoy or is the clyde Mcoy best.
i need a good wah for classic rock 70s-80s
thanks
Dave!

hey guys, just wondering how wah pedals work.. the’ve been around since the early days so they musnt have worked digitally
thanks for any answers

I stupidly sold off a Jim Dunlop Cry Baby back in the late ’70s – wish I hadn’t. If you have one, I’d keep hold of it. The pot, as Lee says, takes more beating than most others. The original 100k Hot Potz is a right difficult find, but probably on Fleeb for sily money. The Hot Potz II is a more economical bet. Be very careful where you buy. They are (for some reason) $40+ on guitar-parts site, yet only $6.95 at B.G. Micro

I know where I’d go 🙂 . I’d put up the links, but yet another little bug is affecting my c+p – apols.

Maybe you just need to replace the potentiometer (vol/tone pot) on your wah, Cry Baby’s are brilliant pedals but the pot does need changing every so often, they just wear out, maybe bass can advise on where to get a new one.
