Title: Zefiro Optical Compressor
Post by: aeroemi on March 24, 2015, 12:25:00 PM
Hi all, this is the Zefiro; an Optical Compressor based on the VTL5C3, so it is a pretty standard design; but I've studied several other optical compressors (Diamond Comp, Afterlife, BBE Optostomp, Demeter compulator...), and I came out with this, containing the best features of those pedals.

Well, it is an optical compressor so transparency is predominant; it is not aggressive and with the added tone control it can shape the tone before the drive stage of my pedalboard. It is definetely Always on!

Wow. Looks really nice aeroemi.  I'm studying the Flatline schematic right now. Really cool ideas in many of these schematics you mentioned. Beautiful stuff.

;) Yes, it's a control acting like a treshold knob. Very useful to restore some dynamic for any fixed value of compression. It is an implementation of a smart idea shared on the forum.
I thought to add a mix (wet/dry) control... but it wouldn't be very useful in a optical compressor design, since it is very transparent as is.

Thank you Brian! Although I'm still far from the standard of the pedals you make!!  ::)

Eh, i kind of like it. It's like the sexy behind the scenes at a fashion photo shoot. :)

The pedal looks great, by the way.

Yes Jon... I have heard of and seen several "Sensitivity" knobs in optical effects and compressors...

My question was basically why he decided to label it "SENSIBILITY?"  8)

Also... very impressed with the pro quality!  :o

Just from your description this sounds like you took a bit of everything to make a perfect pedal. If it sounds half as good as it sounds, you're golden

::) Well, I don't pretend the Zefiro to be considered as a perfect pedal... I just like it a lot; I designed it according to my own tastes... but (as everyone knows), how can you define a pedal as "good"? It depends on personal tastes...

It's silk screened. There's a small graphic company near my house, so they applied the graphic on the pedal according to the file I gave them.
