    All DIY-Boards

    Name says it all. This thread is for boards that ONLY include pedals YOU built yourself. Here's my Acoustic All-DIY board, and it's also ALL-Analog (left-right): T60 Reverberator from Scientific Guitarist (uses 3 PT2399's which is mostly analog). AionFX CE-2 (still the best chorus 45 years...

    Acoustic Preamp Design - Preamp & EQ

    My next steps: 1) fully evaluate its function, sound, etc. tweak values maybe. This might take a few months. 2) re-print PCBs fixing all the minor issues I’ve found so far and any improvements. 3) put together parts list and Tayda templates, etc. Realistically, might be early next year before I...

    Acoustic Preamp Design - Preamp & EQ

    Doubt it, very different builds. Q-tune has a lot of special parts, which is why we only offer a kit. PreQ is a bigger build but all common pedal building stuff. After I use it for a while and fine tune some stuff I may offer the PCB's for sale and have the end user source their own parts.

    Acoustic Preamp Design - Preamp & EQ

    I've talked about this with a few EE's who also hate breadboards, they prefer to solder up perfboard prototypes instead.

    Acoustic Preamp Design - Preamp & EQ

    Way too much to breadboard. In my experience breadboarding often brings more problems than it solves. To each their own, but I'd rather simulate and print (it's cheap), and then fix mistakes and re-print than spend a ton of time breadboarding. There are situations where breadboarding is useful...

    Acoustic Preamp Design - Preamp & EQ

    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...

    T-shirt schematic

    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?

    Q-Tune DIY Tuner kit

    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.

    Q-Tune enclosure size? 1590b vs 125b

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

    Q-Tune enclosure size? 1590b vs 125b

    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"...

    Q-Tune Drill / UV Templates

    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...

    PPCB Tone Generator’s

    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…
