Catalinbread - WIIO [guts]

I dunno, I know that someone asked Nick if they could run their WIIO at higher voltages, and he recommended against it, something to do with the transistors. We'll know for sure in a couple of weeks.

... "recommended against it"? Whether it is technically possible or not. There's nothing in between. If it's soundwise "recommended" is a different question. They mostly use 2N5457 in their designs which can take much more current than 18V. So the only thing is that they have used low rated electrolytics which can not take 18V - and that is something I realy doubt!;)

In any case, this is all speculation. We won't know until we know.
That means you'll get one?

Yes, I have taken some photos, and am just trying to figure out the best way to show it clearly.HEAD wrote:Hi,azrael wrote:That is the plan. Soon, hopefully.
I almost got a V1 in a trade for a Tonebender. One day late!
any news?

I'm going to draw some lines on the pictures to show the PCB traces clearly I think.
I'll give you a hint from my cursory glance at the circuit...three FETs, not Dirty Little Secret based at all!

It begins!
Give me any tips to make for better pics, this is my first time trying to help trace a circuit. topside, added some labels.
Looks a like 3 SHOs? bottom side red is the topside trace, purple is the underside. not complete, but i thought it might help makes things clearer... And the value for the pots are...
Master, Gain, Bass: A500K
Treble: B500K

Dude! That's just great! Thank you very much

Great! Looks like they did it better than Mr. Zachary spending every BS170 a protection diode. Or am I wrong with that? To me it looks pretty much like they did.

hi guys...
here are some pics of my V2... I've owned this pedal for some days... but IMHO there's a great difference between the sound of samples and the real thing
the V2 is pretty useless with the gain under 70-75%... in fact it sounds clean as a simple clean booster like MXR Microamp
at full gain the pedal sounds decent, but it's a mid-gain OD, non a high-gain pedal like samples!!!
Also, if you turn down the volume on your axe the sound became too dark and useless
So, I've sold this because my Colorsound Powerboost clone is better, both in boost and OD settings
Also, I have a DR504 and this pedal doesn't REALLY nails the Hiwatt sound...
IMHO this WIIO is highly overrated

Anyone wanna try taking a whack at a schem? I may try after this week, I have finals coming up in a couple of days...

I'd love to build the V1, does anyone know what the differences are circuit-wise?

^Supposedly has more gain and top end, so probably if there's a resistor at the outputs of each show, it would have a smaller value in the V1. And the treble could be anything, hard to tell without a schem just yet.
Isn't that more your guitar's fault for not having a treble bleed capacitor?gilmour_pugliese wrote: Also, if you turn down the volume on your axe the sound became too dark and useless

I've tested the pedal in various setups (hiwatt-laney-marshall amps, single coils-hb pups) and the result is still the same
IMHO a CS powerboost is better

Well, the Powerboost is a completely different pedal...that's just your opinion.
And yes, it's a treble bleed issue, IMO. When you roll down your guitar's highs, it loses treble. A treble bleed cap on your volume pot will allow treble to return to your signal. So, no longer overly dark and muddy.
