Ashly SC-50 clone

[disssa]

After successfully rebuilding my version of the Ashly SC-40, I came up with the idea of converting my long-used Ashly SC-50 into a pedal too.

The factory schematics can be found on the Internet. My goal was to fit everything into a 125 BB housing. And everything should be made with conventional through hole components.
So I used the schematics to create a pcb.

Next, assembling the pcb...

Had a couple of these back in the day, they got quite a bit of use a number of things. They were super affordable until TapeOp did an article on them.

Next: Enclosure

Nice. I'm assuming this is vca based. Any unobtanium inside?
Also, curious what steps you took to convert it to instrument level.

 

[disssa]

Yes, it is a VCA-based compressor.

Whoa!!!

 

[CheapSuitG]

Will this be available for public consumption at some point?

Being a massive fan of the SC-50, I had to reach out, in case your pedal is available in any way, shape, or form; be it now or in the future.

Thank you much!

@disssa , that looks amazing. Would you mind sharing the schematics? I've only found dead links

Try emailing Ashly tech support, historically they have been great about freely sharing schematics.

I'm mostly curious about the way the VCA is implemented, I might send them a message. Thanks for the heads up

I just took took a look in my ancient folders and found the schematic that Ashly owner Bill Thompson gave me during a factory tour in something like 1979. But then I also found one online here: https://audioschematics.dk/downloadus/schematics/outboard/

That is the one I used.
