In mid 2023 I started designing my own acoustic preamp, striving for similar functionality to the Grace Designs Alix. I was annoyed by how expensive good acoustic guitar preamp/EQ's are, thought I could make my own cheaper. I started with the preamp section of a Fishman loudbox, added a gain...

So I got this T-shirt for my birthday, very cool! But I’m looking at it and they used a 7806 to create +/-5V !?! Am I missing something? And no protection diode on the negative side?

My sentiments exactly... I've done it enough to know I don't enjoy it.

FYI I have two (2) 1590b’s left. No 125b’s. Next batch of enclosures from Tayda are due first week in August.

Build Instructions 1.0.6 is now available. It has updated pictures and a few minor tweaks from before. https://www.q-tune.com/build/

Honestly i knew there were a couple, but i had no idea there were so many. 🤪

Sorry. 1590b

Here’s an updated gut shot of a 1590b, with production enclosure and PCB with momentary disconnect

Bumping this thread. @joulupukki and I are somewhat SHOCKED that our initial orders are heavily in favor of the 125b, like 3:1. I'm wondering why. Like the poll results, I figured most would want the 1590b because it's smaller. But that has not been reflected in our sales. One unique "feature"...

Hi, We have posted the Tayda Drill and UV Templates on the Q-tune website. If you want your own UV design, you can get the dimensions from the drill template and create your own. Hope this helps!

We have plenty of screens now, and a couple 1590b’s left in the first batch. We think we can ship most places internationally for $35 UPS. I'm wondering if there is any advantage of doing No Screen or No Enclosure. What would be the preferred option? a) Full kit - $149 + $35 shipping b) No...

Ah you’re right. Jumpered but that didn’t help. I checked the diode, it’s right, have 9v on the other side. I’ll have to probe around…

I put this together and it doesn’t work. First time SMD for me, it could be a lot of things. LED doesn’t light up. No sound. I wondered if the jack needs to be stereo? Is the ring used? I only stock the mono version and I clipped the ring lead off. Shouldn’t matter since there’s an on/off...

Building kits!

Update: Tayda has shipped and expected delivery is Thursday. Hoping to ship all kits Saturday. Backstory: In the past Tayda has been very consistent to deliver 12 days after I order enclosures, which is pretty amazing coming from Bangkok, Thailand. Except this time, they informed me late last...

Our build instructions list the difficulty level as INTERMEDIATE, 3 out of 5 stars. Maybe @Robert or @keyth72 could comment on the build difficulty relative to other kits or pedals.

Production PCB's Assembled: Waiting on Tayda...:(

While we don't plan to sell the PCB by itself, if something like the above happens... yes, we would sell you a replacement at cost (mainly just shipping). Hopefully it doesn't come to that.:) This should not be your first pedal kit. But assuming you've built a couple pedals, there is nothing...

@Robert prefers 0805 size, his frequency generator kit is based on that.
