Bring out yer Diptrace

Dual rectifier inspired JFET preamp pedal with adjustable front end boost and buffered bypass. A little lopsided I guess. Wasn't sure I was going to be able to fit this into a 1590BB2, so I opted to go with a landscape 1590XX. This is my first big project after only doing small adapter boards so far. There's probably some questionable design choices here or there, but I'm like 90% sure it's going to work 🙃 Grounds unpoured for the screenshot. I tried to keep the signal traces to the top layer and power to the bottom layer as much as possible, inner layers are ground.

Looks nice, where is the setting for those rounded trace junctions? I can't imagine where I would look for it in DipTrace.

Right click on a trace, select "Teardrops..." and activate the T-junction setting.

There should be no vias on a board that large and spacious, but that’s just me 😂

Probably not. But I've spent too much time on this already, so no more shuffling around components to optimize traces. It is what it is :D
 
With higher gain circuits, I usually do a couple of revisions on the layout because it’s horrible to build a prototype and then find issues. Just my experience of course.

This. If the input is just a hair too close to any part of the output section….

I’m definitely answering for him but yes 😂

I'll see how it works out. Will do some final adjustments until mid next week and then place an order. This was maybe the 3rd or 4th major revision after having to start over a couple of times because of questionable layout decisions and not really knowing what I was doing in the beginning :D I definitely have a new found respect for Robert and anybody who designs boards on a regular basis.

Getting a hang of this I think. Is there an easy way to round off 45° angles in traces other than doing it all manually with arcs? Is this easier in KiCad?
