The "Woody": a cheap acoustic simulator

[smoguzbenjamin]

Get well soon, mate!  

I do tend to sortof plan where the parts have to go before building anything. So far I have a couple of perf layouts for phuncgnosis and the GGG minimixer and a fuzzbox I thought of, and no projects finished I can't choose, but I think the woody'll be the first thing to come after the mixer and my pedalboard. So that would make it about january when I finish it

Hello,

Ok i know this thread is old, but I am interested in making the woody, i see smoguzbenjamin that you were after the perfboard layout. Did mark ever get one for you or does anyone else know of one? I am not to keen on making PCD board for it.

Oh by the way its my 1st post here, Im from australia and the only project i have completed is a 'little gem' from runoffgroove who i have noticed are lurking in these fourms.

It's not perf, but Pablo (aka Gringo) has a nice pcb layout for the Woody. His layouts are nice, compact, and well thought out.

Thanks for the kind words!  :oops:

You're welcome Pablo.  I'm sure there's many out there besides me who have used and enjoyed the nice pcb layouts you did (on your own time) for the ROG ckts, as well as the ckt's on your own site.

So..thank you!

Looks like one day ill have to give in and decide to use PCB layouts soon.  
Thanks guys.

 Hi!

Mark,
Is the low [input] impedence (10k) nessessary to achieve the sound or can a Hi Z (1M) non- inverting stage be used.
Thanx
John G

Was this question ever answered somewhere?

Thanks, T.

[Mark Hammer]

*I* thought it was answered.

And the answer is "Yes, a higher Z input is preferred."

[Thomeeque]

 Same as yesterday with Boss AC-2 I did emulate Woody in LTC today, here's my LTC schematic:



woody.asc

if somebody is interested..

Again, it comes with no warranty, user-guide, support etc., but it's for free

Great, thanks Mark! T.

 Btw. Mark, would you remember what value was 500k trimmer approximately dialed to in your Woodydemo.mp3 ?

Btw. Mark, would you remember what value was 500k trimmer approximately dialed to in your Woodydemo.mp3 ?

Not at all. And quite frankly, I don't think it matters, really.  Pickups will vary with respect to how much high end they produce, and the trimpot is simply there to assure that the highpass-filtered top-end is sufficiently robust to generate the additional harmonic content.  If player A uses a 250k pot on some overwound single coils and player B uses a 1M volume pot with brighter underwound SCs, the trimpot will likely need resetting.

Just found this project, very surprised with how good it sounds.

Any ideas on how to get a more acoustic sound with humbuckers? If I understand it right, it's just hard due to humbuckers being darker, right?
What if a humbucker were wired in parallel, on the neck pickup? Would that help?

You and me both!

It assumes a certain amount of top end to work/start with, so yes, your instincts are right.

My gut sense is that cancelling one coil in a humbucker would eliminate enough of the body of the tone to make the top end seem a little more present when prcoessed through the Woody.  Another trick might be to have a compensated volume pot on the guitar; that is, bypass the input and wiper on the relevant volume pot with a small-value cap (1000pf and below) to retain more of the top end when you turn the volume down a bit.

Of course, now this is starting to remind me of the way my mother would end up having to buy a new sofa and coffee table to go with this darling table lamp she found....  

So, rather than overhaul your rig for the sake of one stinking pedal, let's just leave it cancelling a coil in the bridge pickup and straddling that volume pot with a 1000pf cap.

Haha, it's not a big deal for me. My neck pickup on my Les Paul has a switch to do series-split-parallel. I've been using the split setting to clean up my tone, since I used a one channel JCM800 type deal. Other days, when I'm less lazy at gigs, I'll plug in my Strat.

Something like this might spice it up nicely.
