All Cast (dual setting Hudson Broadcast)

[sonic_explorer]

Here is a build I finished recently of a Hudson Broadcast clone in a 125B with the ability to switch between two sets of controls and between 9V & 24V.

The right footswitch turns the effect on/off and the left footswitch switches from using the right column of controls (Level, Gain, & Tier switch) and the left column of controls. The left led switches between red and blue to show which set of controls is activated. The Low Cut control is active in both modes. Both footswitches use soft-touch momentary stompswitches and a relay system with microcontrollers to switch things.

I did the board layout and had to use both sides of the board to fit everything with the bigger 35V capacitors needed when in 24V mode. I think most the components on the back of the pcb are just capacitors laying down horizontally.

I am still auditioning germanium transistors to use, but I am really pleased with how the switching turned out and love the UV printing I had done through Tayda. I think the build would be maximally useful if I had used a stacked pot for the low cut so the left and right controls also have independent control of that.

Great build. I am a duocast believer. I'd want a low cut for each side as well. Very nicely done

That's a sweet looking build. I agree too that this circuit works beautifully with the amps I use.

Really nice layout and build!

Have you tried bypassing the transformer? I couldn't hear a difference and it makes a big cost/space saving. Less mojo though.

You could not put it in an enclosure to save $6 too

Great build! Loving the added soft switches!
