Well I removed the old switch/pcb and wired a new switch in - the old fashion way. It works. I know those pcb switch boards are SO nice, doing it the old way took a long time. But I will say the amount of heat you have to put in is a lot less for a single wire than filling a PCB hole. FWIW.

I agree it seems like it's the switch. I checked the switch with a MM, seems fine in both play and bypass. Next most likely is that 3DPT board, or some of the connects between them. I used a 6 pin header. I suppose next step is to take the switch and 3DPT board out and hand wire a new one in...

So I should remove the switch and wire in a new 3PDT the old fashion way... probably. I'm not sure if the main PCB is marked.

I wondered about that. So I jumpered the top left/right pins on the switch thinking I'd create the standard bypass wiring. That didn't help. So now I'm more confused than I was.

Odd issue. Sounds great when engaged, but in bypass mode I get no sound. I *think* this is True Bypass. What would cause no sound when bypassed?

Digging around for 1/2 hour, I still can't find them for less than $1 each in bulk. Tayda is $0.55.

I’ve looked in Ali. If you could provide a link to the mono version, I’d appreciate it👍

Yeah Tayda and Amplified Parts call them panel mount, but I use them as PCB mount. I suppose either.

Production PCB's were ordered Monday, expected delivery ~July 2. This is about a week later than I had expected, but worth it. We sent out a few test kits to specific people to get feedback on the overall build experience. @Robert was one of those and gave us some great feedback. @Robert...

I've been buying these Low Profile jacks for years, love them. I didn't realize until recently there are 2 flavors: Mono and Stereo. Recently for the Q-tune project, we settled on the Mono version... because it's switched. With nothing plugged in, it will ground the input which prevents Op Amp...

Gotta (probably) be somewhere between pin2 and ground. Look at schematic. Probe voltages on good side, compare to bad side. Example: junction between pin2 and R22. Also junction between R22 and C17. Etc. I checked a lot of those resistors and they look right. Might be a bad solder joint on one...

Show picture of the wiring for switches

Please confirm you have a high side and low side gain. R20 and R30 are the same, high side. R3 and R16 are not, low side

I’ve made resistor mistakes before, like installed a 392k instead of 392R, can significantly after your gain stages. It’s tedious but at some point you should check each resistor color codes.

For any international customers, I've been thinking about a No Screen / No Enclosure option. Purchase the screen here: Waveshare with touch. Flash the screen yourself using the Web Installer. Purchase the enclosure from Tayda. Drill/UV templates provided. We'd subtract our cost of the...

Screens arrived! Still planning to ship in 2 weeks, by the end of June.

Black is GND on the screen. I always double check that.

Thanks for asking: - We didn't sell out so, we are leaving the orders open at the introductory price of $149. - We have received the 20 screens and 95% of the parts. - Production PCB's and enclosures are due ~June 27. - Hopefully, should be able to ship by the end of June. We suspect that...

Pre-orders are live and available until Monday June 9, or until we sell the first batch of 20. We are planning to ship last week in June, although if we run into problems it will be no later than mid July. Order at www.q-tune.com for the introductory price of $149 + shipping. Purchase options...

Sorry. If things go well we plan to move to Shopify which will have PayPal. But for now Stripe and its options are best for us as we get started.
