Who has installed Power Scaling with a kit available here: http://www.londonpower.com/kits.htm Are the instructions clear? I have built a few pedal from kits from Build Your Own Clone. http://www.buildyourownclone.com/index1.html They were very easy to assemble because the instructions are quite clear. On which amp(s) did you install London Power Scaling, how difficult was it and how do you like the result? Thanks!
