Here is Rev 2 of my looper box. This includes a THAT mic pre in front. Upon first firing this didn't work but after digging more on the diyaudio forum I found someone doing the same project as this one, and doing it in an easier way so I may make my way to a rev 3 with more features

Well, I guess I messed this one up. I'm wondering if I just needed to connect this V- pin to my ground? I left it unconnected without thinking about it. I used the Mean Well DPBW06G-15 attempting to convert +48V to +/-15V: datasheet Edit: this fixed it

Wow I searched all over for the crap fi schematic with no success. Thanks for this!

I have one more question, does the "Common" pin on a device like this typically mean it connects to Ground? datasheet

So, I've built a THAT Mic Pre for which I have a 48V power adaptor. I'd like to make a new box that includes this preamp, then takes that signal straight into a balanced line receiver, sends it to a pedal circuit at 9 or 12V, then goes back to a balanced line driver and sends it to an XLR out...

Simply because I didn't know these existed. Thanks!

As an ongoing work on my XLR looper, I'd like to include a preamp inside which requires +48V power. Let's say the rest of the circuit requires +/- 12V, and I'd also like to include a pedal effect which would take +12V. Is the diagram I've drawn below feasible? Is 48 to 12 V too much of a...

Here is my schematic, I will PM anyone that wants a Google Drive link to my gerber zip file that I had fabricated at JLC (I did increase the mounting hole size). Note: I don't technically know what I'm doing, I stole most of this from the DIYRE Color format schematic. I have done some test...

OK I will get this to you or post a link later today. If I don't get it today remind me. The one mistake I made on this was making the pcb mounting holes too small. I had to drill them slightly larger with a drill bit. If I can figure out the correct size for them I will before I send this

I designed the PCB. I can provide gerbers and a schematic if you're interested

This is a box that takes a balanced line level input from my preamp and let's me send it to pedals and back to the computer I have some more ideas for a future iteration such as including a preamp inside and others

I never had a micro amp but I really like my micro amp plus. Recommend

I've never played a harmonic percolator before. This thing rips. I made the silicon version with LED clippers and just basic 3904 and 3906 transistors. Gonna work on a faceplate here soon

I've invested in a project that called for this DC jack which is now discontinued: Jack 1 I've researched replacements and it appears this one has the same dimensions and layout: Jack 2 My question is, the schematics are showing a slightly different pin numbering and I can't figure out if...

I built one of these and I can't for the life of me figure out how the knobs interact. It also felt like the compression knob was turning the wrong way maybe

I just wanna say I ordered candy metallic blue and purple and they both look sick as hell

Hell yeah

Effects Layouts has a little PCB that adds a balanced signal out and may achieve your goal. It attaches to the footswitch

Nice job figuring that out. How did you modify the bass pot? Does it still connect to the PCB?
