well there is definately a big difference between using an HCF40106 and a 74C14N, which is the stated equivalent to the CD40106 on the MFOS website. The 74C14N is a lot more 'gritty' sounding and runs a bit slower.

I think i prefer the sound of the HCF40106 but i'm not 100% sure

I've made some demos of my WSG using the HCF40106 and the 74C14N with the controls in exactly the same place. Each demo has the HCF40106 first and the 74C14N second.

Jeez, that is a pretty dramatic difference.

HCF is much nicer... but the other one is cool too.

Hiya all, tis my first post so first off.. great forum here, good attitude and all!
had to post because I love the WSG, I have built two of them from the vero layout by Unkle Krunkus (anyone used that?) it sounds great to me (I used a cd40106). The LM 741 is a single op amp, has anyone tried any others in its place? I haven't yet but will do when I get hold of some  :). I just checked this new PCB from the MFOS site and it has extra switches!!  ;D Is there much difference to the original WSG? I'm hoping I can add these extra switches to my vero build ;D

fegg.

yeah, got my MFOS pcb, got to get parts ...
I think I have to build it twice one with HCF4106 and one with the 74C14
... a must have :)

I can't remember, does the original WSG have two voices?  Cause that'd be a big difference.

the original has mostly the same pots (only coarse "oddness" cutoff and no resonance) but minus all switches apart from "Wackiness"  ;D ...I'll try and drop them in.

p.s. just realised my 2nd vero build had two resistors misplaced, but still made Noise  ;D

hey, the red box looks NICE! very professional!

i like the idea of the old camera. i have a bunch of those, actually.

i think, before i build a wsg, i may want to learn how to print circuitboards like the bigboys do. i mean, i might could fake it with a generic pcb, but a printed board would make life a lot easier.

My advice is if you don't actually have to, then don't bother. If you can get a ready made board then you might as well go the easier route, although i'm sure just the PCB was a lot cheaper when i built mine.

I've never tried a WSG on stripboard but i've definately seen a layout for it somewhere on the net. Its not actually that complex component-wise. Most of the wiring is for the pots.

yeah, i was checking the layout out, and nothing on it even resembles  that of a strip board.  i would have better results hand wiring everything than to do that! ;-)

Boy, I hate to disagree with the man himself, but I found a PCB to be a great help when I made one of these.  There are some great tutorials out there, and it's a skill that you'll use over and over.  Check out Getlofi's videos on the subject and do a search for "Muriatic acid PCB".

Totally worth your time.

i agree, what i was trying to say there was that its a whole lot more effort to make your own PCB than it is to just buy one if they are available, especially if you aren't that experienced at it. Plus you can more or less guarantee that a comercially produced one is going to work.

Having said that, i think it'd have to be something a little more complex than a WSG to make me actually make a PCB but as i say, i've never attempted one on veroboard

i think from a learning standpoint, making a pcb may be bennificial. of course, i like the instant gratification standpoing too.  :D ;D
