I can find anything schematic-wise, and I was seeking all bloody day...

It's just an audio patch (booster/compressor) part of the circuit, no wireless circuity included. Big-ass version is very expensive, but cheaper, more pedalboard friendly version is in works

Here is an article with some interesting specs.
Pretty low input impedance.

Wow. Something I really never heard off.

Seems a little that this Dallassolo guy is creating it's own hype. And does a pretty good gob at it.

Does anyone had a chance for underskirt checkup of the pedal version?

[modman]

found something of a gut shots, but not much to go by

I've found this
hope it helps

I wonder if the bypass method is akin to mictester's scheme?

Using a relay you mean? Pretty common... or am I missing something? I just glanced at the pic...

Yes. But driven by a SPST switch and what looks like a two transistor circuit; could be similar to this:

Guys
Ive found this
They say in the page that since theyre publishing the PCB they have taken counter measures for the tracing to be ineffective. But with these photos we are back in the game of realizing what does it do. We can figure almost everything

Guys, some months ago I was thinking a little about this pedal after I read in some sites that this gadget is a compressor and expander with some equalization and boost improvements, I thought about post a reply but I decided to wait a little because probably the schematic would be posted in a little... Ok, I'm still waiting.

What sollo dallas does is what dbx system does in tape recorders and others ciruits such as digital delay/reverb to avoid hiss:





In the first picture atached by tiococo there a dib-16 IC next to the foot switch, there is caps in the pins 1, 2 and 3 like NE571 in compressor configuration:



What do you guys think about?

[EddieTavares]

Ne571 as compressor:



And possibly a one of that in the PCB, three yellow caps connected to the pins 1, 2 and 3 as in the schematic above:

NE571
SA571

I tried to link this image twice:

[clintrubber]

Stating/or possibly repeating-ting-ing-ng-g the obvious:

The logical thing to do it to listen which BBD-based analog delay with a bypassed BBD & the associated pre- & post-filtering comes closest in sound to the SVDS.

That is what I think it is:

That is what I think it is:

Instead input, output volume boost.

[FuzzMonkey]

I'm a big AC/DC guy so it's good to see some movement with this thread. Keep it up guys!

[apollomusicservice]

Many help would if someone has this device and if wish to make and share more inside photos.
