The Persuader from MOD Kits DIY (available at modkitsdiy.com for about $65) is a U-build-it, starved plate, 12ax7 distortion box kit.  It arrives as a collection of parts to be assembled into a powder-coated purple, pre-drilled Hammond-style cast-aluminum box.  A 16 page assembly manual identifies all the included components, and has a solid, but brief tutorial on soldering.  At the end of the manual are various tear-out drawings to use as guides in the build process.  The step-by-step build instructions were clear, and if you've built a few kits of reasonable complexity, it's fairly straight-forward to build The Persuader.   There were one or two steps in the build I thought were not in ideal order;  I'll address those later in this review....
