Boss AC-2 Acoustic Simulator

If it is helpful to you, I was looking at this schematic yesterday and already put together all the components into a list. This should save you some trouble. The only thing I was not sure about was some of the capacitor ratings, expressed as 1/50 or 10/16.

The original is not doable on vero (easier to buy second hand for £40/50)
I don't know the second one.
Is the schematic verified?
Any video or sample?

[spacecase96]

Hello Alex thanks for taking a look at the AC-2 Acoustic Simulator, I figure it was way to big to be vero'ed. The second schematic I can't find the site or remember the site I pulled it from.
Anyway thanks for all the new addition of vero layouts you have added to this site. Most Excellent! Party On Wayne!!!!

I found where I that second schematic came from

Unfortunately the verified layout doesn't match the schematic 100%.
I'll try to find the time to double check it and draw a layout in the next few days.
