A couple of vero builds

[Guitarmageddon]

ROG Matchbox (Matchless DC30)



Does mostly nice cleans and has a rotary switch tone control.



Codtocomp



An optical compressor with a clean blend and bright switch.

I like the clean blend mod. They both look fantastic, man

Nice builds, as always! Which compressor circuit is that?

[Guitarmageddon]

Thanks gents.
The compressor part of the circuit is based on the DOD 280.

I love the knob layout on the DC30. Nice builds.

Could you link to the vero layout? I seem to have to build every compressor I come across...

Here's the DOD280 layout I adapted. I added the blend part myself, but don't have a complete layout drawn, sorry. The bright switch is a 1n cap on the level pot, an idea inspired by Mark Hammer's Ross Compressor mod.

Sweet! Thanks for that.

Awesome job!  What did you base the clean blend circuit on?

Thanks. I made it up myself, but it's a little like a buffered splitter design by Jack Deville.
There's quite a few out there, including some really simple FET based ones, but I've generally had better results from the opamp designs.
I think I posted the layout in one of my other build reports...

Noice... I always respect vero builds if only for the fact I honestly don't have the patience for it myself

Thanks again, I couldn't find in any of your previous build reports...maybe I'm not looking in the right place...

Come to think of it, it might have been another forum...
Here you go. You may need a pulldown resistor at the send, and increase the value of the mix pot. 500k or 1M should do it.

Thanks again!  That looks like a great design.  I'm one who has to try every blend circuit I see  .
