ROG Tri-Vibe

[slimtriggers]

My first modulation effect.  I've seen a few of these around lately, and I've really dug the demos I've heard of it.  Since there's no fiddly biasing or JFET matching, I thought I'd give it a shot.  I'm glad I did

Man, this layout just barely fit in a 125b, I was worried I'd have to go up to a 1590bb.  I sanded the board right down to the very edge of the ground trace, though, and I got it stuffed in there.

For some reason the font on the ROG build document reminded me of the Rocketeer, so I went with that theme.  The graphic is a toner transfer with a spray can clear coat.  The LED in his gun pulses to the LFO speed.  At higher settings it looks like he's shooting a machine gun

Only have iPod pics right now, sorry.

Tight fit.

Excellent! I have a tri-vibe board ready to go...just waiting on the parts. Where did you get the LM13600? I only found an LM13700. Love your design and LED placement, too.

nice, the tri vibe is a cool effect. home etch?

Yeah.  I guess I'm weird, but I kinda like etching and drilling boards.  Definitely prefer soldering on fabbed boards, though.

Thanks!  I got the LM13600 at Tayda.

Awesome etch, and one of my favorite circuits. Nothing else sounds quite like it, and the vibrato setting alone is incredible. I think this will be ROG's crowning acheivement for years to come. Even more surprising is that it hasn't (to my knowledge) been stolen by any booteekers.

That is a great looking pedal.  Very nice etch.

I am curious about the Tri-Vibe and hope to give it a go one of these days.

loved that movie when I was a kid!

Yes, it's really a great sounding vibrato.  And despite the ROG complexity rating, it's really a fairly easy build.  I'd rate it as "cowboy" on the Madbean scale   The only negative with it so far is that it can be a bit noisy with a couple of drive pedals after it.  You can hear the woosh-woosh of the LFO when you stop playing.  That's only with a fair amount of drive, though. 

It's definitely worth building, for sure

i'd say it's a must build! i don't say that about too many pedals.

the only thing that makes it tricky is the OTA makes it a bit harder to debug (compared to, say, an opamp).

That's very cool,I love the creativity

[wolfingsworth]

What a great build! Those graphics look so good on that bare metal it hurts!

[juansolo]

It really is a unique sounding thing and can get really leslie-ish. Love them.

Nice, Like the graphics.
The perfectly square green wima sitting in the middle just makes me smile for some reason.

Cool build

Yeah, I was freaking out that I didn't have a smaller cap.  Fortunately there's a big empty space right in the middle of that layout, and it fit right in
