Title: Dual Function
Post by: pickdropper on February 07, 2014, 02:18:56 PM
Finally boxed up my DuoVibe and GreaseGun builds from the Function f(x) fundraiser sales.  Brian and Forrest did a nice job on these.

The only mod I made was to put R7 on a 250k pot with a stopper resistor.  This functions as a sort of "pre-gain" control.  Forrest gave me the idea because he likes a lower value resistor there.

This build was a bit of PITA.  Sometimes, when you laser etch, it looks really neat and clean under the powder.  This one was the opposite of that: it took quite a lot of scrubbing to clean the etched areas of the enclosure.

I'd deal with the pain if the result was perfection.  I love it!

It's a laser etch. I love it to death.

Those are fresnel lenses by VCC.  I got them from Mouser , but I  certain that there are other vendors that carry them as well.

It was a fine question.  The only way to know is to ask.  Thanks for the compliments.  :-)

Nice job.  I have a question about the frensel lenses.  I have a bunch of these from Mouser in both 3mm and 5mm varieties.  There is a "holder o-ring" which I have, but it looks like you have some kind of plastic clip.  Do you know the part number or where to get these?  I assume they work better than the o-ring.

Great job Dave! I love the grid you used in the graphics. Very fitting for an f(x) build!

Very impressive, as usual. I was going to do ours as a Ffx triple but am now considering sticking the fuzzes into a 1590A. Purely because I can.

That's what I did.  I like the fuzzes in a 1590a with a toggle switch to choose which effect is active.

doesn't get much cleaner than that. the etch looks fantastic. a design of that type is so difficult 'cause any variation in the pattern sticks out like a sore thump,but you really pulled it off wonderfully.

Indeedy. We've got it down to two knobs and a switch :) (bit of dual gang wafer swappage). Have to admit that Cleggy did the boards though. I tried but I couldn't see the resistors  :'(

That's a cool approach to the knobs.

Sometimes it is an advantage to keep them separate.  I usually set the two fuzzes differently, so I like being able to toggle between them without having to twiddle the controls.

that is one fine build. Wasn't expecting anything else when I saw your name as the author. What is the 4th knob on the grease gun? Pot instead of R7? what is that changing?

If you read Brian's build doc , it's an optional resistor that knocks down the bass a bit.  By turning it up, the bass comes back (and the gain seems to increase a touch as well).  I put it in the experiment with, but so far I think it sounds best stock.

It sounds really good, actually.  I like the low gain drive of the GreaseGun quite a bit.  I could see it being very useful on a pedalboard.  I like the vibe, too.  I prefer the LFO on the sine to the choppy with this one.  I also think there is a slight treble roll-off with a drive pedal pushing it.  I noticed it with the GreaseGun and with a Klon.  I might tweak things a bit, but I like it even without any changes.
