My first build for june, the Prismatic EQ by Effects Layouts.

This one was a really easy build. All the components were readily available, and everything went together very naturally.

This was my first experience with both 9mm pots and center detent pots. It not be my last with either.

I haven't used graphic equalizers much, but I am really impressed at how much tone tuning can be done with all these knobs. I'm looking forward to giving this one a lot of attention in the near future.

The enclosure is a 125B from Love My Switches, and the art is waterslide. I'm really happy with how the decal went on.

Nice job, especially with the decal!

Thank you! I must admit, though, it took 3 tries.

I wouldn't have guessed that's a waterslide. You killed that!

Looks fantastic, great job!

I built that same pedal not too long ago (actually gigged it tonight). I actually go back and forth between it and my Source Audio EQ2. The ge7 is great if you only need it to do one thing, and want to be able to quickly and easily do some quick tuning on the fly (especially during a gig). The EQ2 can do so much (graphic and parametric capabilities, not to mention all kinds of other goodies), and IMO sounds amazing. But the interface doesn’t really lend itself to quick adjustments in the heat of the moment.

Anyway - what kind of LED bezel did you use for this build?

And wow, I wasn't familiar with the EQ2, but now I think I may be in a rabbit hole. That thing looks sweet! Too bad it doesn't appear to be a good DIY candidate, but they can't all be. lol.

The LED bezel is just the regular Tayda 3mm metal bezel, but I put it through an anodized toggle switch washer from LMS. It's a nice look, and gives me a little more confidence when it goes over a waterslide. Those little bezels have such a small, sharp shelf, I worry about them cutting through the decal paper and leaving a rough lip.

Looks great!

I am building one of these in the near future and am concerned about getting knobs that will fit. What is the diameter of the knobs you used?

Also, yes that Source Audio EQ2 looks cool!

The knobs are "The Magpie" from Love My Switches.
Link is here.
The diameter is 12.5mm.

Thanks! And did you drill yourself or have Tayda's drill service?

 

[Zennmaster]

I always do my own drilling.

 

[joelorigo]

Ugh, I hate doing my own drilling!

Hi, I have also built this pedal, although I can't get it to work. I have used an audio bypass to check each component. I am getting a very quiet signal from all of the components, so they appear to be soldered in ok. I even get a signal from the last capacitor before the out pin, but no signal coming out. It is getting power with no issues. Any ideas what's gone wrong?

 

[jaymucas]

Of note, the sound I get when using my bypass is much lower than the input signal. The signal is effected when I adjust the potentiometers

I would suggest to start a thread in the "Troubleshooting" area. You will get help figuring out what is wrong. Include photos.

I would highly recommend you make a new post over on the troubleshooting section of the forum. Be sure to include photos, preferably of both sides of the board.
