Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter
Here is a layout for the Rockett Flex Drive.
You can find original thread and schematic here.
The layout has already been verified by Gavin (Hozy31).
