From the post

Well as usual just finished a round of exams, so it's time to start posting the layouts I did when I was taking study breaks. This time I'm going to space them out so there's not a sudden flood.

First up the 18v Colorsound Power Boost. Same topography as the Colorsound Overdriver, but ran at 18V, and to my ears boarders on a fuzz. I made 4 different layouts, 2 identical to the original (early & late version), and 2 that have an added master volume pot. On the original the pot labeled volume is really more of a gain pot then a true volume pot, so I figured that it would be much more usable to be able to max the gain and control the output level. The original came with BC184L transistors, but you should be able to use any NPN Silicon Transistor.
