Rather than try to build stripboard layouts on perf, I would try to build some simple effects from layouts that are meant for perfboard. Runoffgroove has some, and some of the simpler circuits at
http://effectslayouts.blogspot.com/ would be doable. Perfboard has the nice property that you can lay out the components in a logical way similar to the schematic. Try something like a fuzz or DOD 250 overdrive.
