I can confirm no Tariff charges when ordering to New Zealand, I imagine it's the same everywhere outside the US.

If you want to calculate the actual frequency I use this calculator. It's essentially the value of R6 or R12 and the cap value. https://www.digikey.co.nz/en/resources/conversion-calculators/conversion-calculator-low-pass-and-high-pass-filter

Anyway see how in the first "tube" there's a 100p cap? That forms a low pass that rounds off the harmonics. You can additionally add that same value cap to the other two clipping stages. You can populate R6 and R12 with both the resistor and cap to create the same parellel arrangement as C3 R4.

The tone knob isn't accomplishing that for you?

Hey folks. On GroupDIY it's mentioned the BC549C (which I already have a bunch of) works in Neve preamps. Would it work in the Pastel too? https://groupdiy.com/threads/replacements-for-bc184c-transistor.51340/page-2#post-685599

This is the probably the first time ever I've been glad to be doing this hobby from New Zealand.

Thanks so much. This is super helpful.

Actually using the GitHub tool above does seem to take away a lot of the guess work. Does anyone have an example BOM I could see. The FAQ on JLC doesn't make it super clear exactly what column they expect. I'm using DIP-Trace.

Hijacking this a bit I guess? I'm looking into designing some SMT stuff for Assembly, but there's so many components on the JLC list, and the search function is also kinda bad? Has anyone maintained a library somewhere of good parts to choose?

I'm thinking of getting some daughter boards printed for SMD Fets, Op-Amps, and other SMD stuff. What is the most economical way of getting them printed? Do you create your own pannel boards or do you send the small PCB and have JLC or PCBway do pannels for you?

I'd deffintely be interested in the Drive only boards, I think mostly the E2, O2, and R2. I think they'd all be a great resource to have though.

Ah ok, so the topology is the same but ?most of the component values are different?

Out of interest, how many of the parts are different between circuits? I guess my question is, could you assemble a version that has all the common parts populated and then you just finish off the rest? I personally would only be interested in the drive section I think, not the cab sim or the...

The reason I ask is, when I checked out the Diezel website, it says the VH4 preamp requires a 12-18v input which makes me think the regulator does not have a step up functionality.

I've looked at the spec sheet for this part. I see it has a maximum input voltage of 30v. But does it have a minimum voltage? For instance if you fed it 9v would it output 12v still? Or do you need to supply it at least 12v?

Ah ok cool. So all the"diffused" LEDs will have the clipping / vf characteristics that you would expect?

Sorry to necro this. Looking at different Diodes for clipping. This tayda one has a blue shroud https://www.taydaelectronics.com/led-3mm-blue-diffuse-lens.html This is clear blue https://www.taydaelectronics.com/led-3mm-blue-water-clear-ultra-bright.html In the specs they both say emitting...

Anyone seen the inside of the new Revv Anniversary edition pedals and seen what they changed? Was thinking of doing a modified build to compare.

Hey folks, I'm just dipping my toes into designing my own circuits so I could use a little bit of help here. I tend not to put tone or volume controls into my guitars, preferring the pickups to go straight to the jack, maybe via the selector. Occasionally this leaves the guitar with too much...

I guess my other question is, Mouser has a range of Hammond transformers, I'm using their direct box one to make my passive DI box. They have some reasonable priced ones, but the response tends to be 150hz+. How much roll off actually is there below that range typically? Guitar doesn't need a...
