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's a version of the Clark Gainster for those who don't want to use the massive paper-in-oil caps in the version posted previously. I only put in the large axial 100u cap because there was a bit of space in the bottom right of the layout and I had some that size. You can obviously use a smaller radial cap here but there's no scope to further compact the layout because of the other components around it. Still this will easily fit in a 1590B and so gives an option for a "Small Box" Gainster.
