Pictures!

[rustypinto]

All these pics are on my myspace too, including the rev A (through hole) version of this, as opposed to the above, which i am using for production.

Ouch...

How so?

[frank_p]

How so?

You placed all those SMC by hand ?   

[rustypinto]

Yep, and soldered by hand for this prototype.

I have a small SMT re-flow operation setup for production. Its twice as fast as the hand placement of the same amount of through-hole components.

is this considered an analog delay? that's pretty tidious stuff. it looks very nice!

[rustypinto]

Yes, the signal path is completely analog with the use of BBD IC to implement the delay. The MCUs control the BBD clock via potentiometer or tap switch. I have a demo in the works as we speak...

Hi
This is the "Tremtation"  It's a slightly modded "Tremulus Lune" tremolo fitted in a small box.

[Akridosity]

Impressive!

Wow.
I wonder what it does.

[jacobyjd]

Wow.
I wonder what it does.

Think of anything that you ever though was awesome.

Now--think of a tremolo.

Now--think of them both together.

(and check out cloudscapes' blog...he's got details there. It's pretty amazing.

Wow.
I wonder what it does.

programable/drawable tremolo, I think

That is pretty awesome. So you made this all by yourself?

[John Lyons]

Very cool Etienne!

[cloudscapes]

Thanks John!

Thanks. And yeah, by myself. A real learning experience.

Hi there, my last build a "WYNIAB", that's "what you need, in a box" and really what do you need more than an HW89 and a Rebote!

Cheers

I'm having trouble telling from the pics of the WYNIAB: is that a sloped console style lid on the enclosure? If so who makes that?

Yes, it is

I have some of them, also half size of this, you can see them on the FS area http://www.diystompboxes.com/smfforum/index.php?topic=76965.msg630329#msg630329

Ciao

Are the resistors blue because they a metal film?  I've only used the black ones.  Out of curiosity, do you here a difference between your through hole design and surfacemount design?  I'm not superstitious, but was wondering if there was a noticeable difference between big film caps and surfacemount ceramics?

The resistor color is blue (i suspect) because of the manufacturer, KOA-speer. These particular resistors are thick-film types, which they specifically recommend for audio.

I notice NO difference between through-hole and surface mount versions of this pedal. I've done extensive A/B comparisons, where the resistors in the through-hole case WERE metal film, and the differences were non-existent.

As for the caps, i used multi-layer ceramic, through-hole AND SMT for both versions. Again, no difference there.

Its an interesting debate that people think surface mount resistors impact tone, but they certainly don't. Resistors serve a very basic function; to resist electrical current. When doing this function, power dissipation becomes an important factor. Power dissipation and mounting style are what set these two resistor technologies apart. They're not frequency reactive devices by nature, and until they take on such responsibilities (where they would just become capacitors or inductors), then they will never affect tone. Its also important to mention PCB layout for completeness. Just about every SMT layout uses vias, which have a certain amount of inductance associated with them. Inductance is of course reactive to frequency, but it only becomes noticeable at very high frequencies associated with very high speed designs (memory buses, CPU buses, etc.).
