First thank you for this great resource...Hey there! First thank you for this great resource. I’ve built lots of fun pedals and learned a lot. I just built this one. I ditched the 10k volume for a 1k, since full gain (volume) @ 0 ohms and way clean @ under 1 k. No more bunching up at the end and very controllable. Also, switched wiring on volume (volume 1&2 on the left, volume 3 on the right). Now it works as expected, with full gain clockwise (0 ohms). I also got rid of the top row, moved the 9V down and moved the cut over, since I have nice 30x15 Stripboard. I used 2n5088s, which match well with the hfe of bc184l and they sound great. Finally, I tried it @ 18volts but I actually think it sounds much better at 9 volts.

Instead of the 10 k they were recommending a 5 or lower. I built mine with a 5k. The fuzz side of things kicks in a bit earlier, but still at massive volume. So perhaps try paralleling a 5 or 10 k resistor across your "drive" pot.

I used BC169Cs instead of the BC184, just had to change the order CBE to ECB (Fun!). I only issue I had was I had to change the cable going Vol Lug 1 swap to Lug 3 and Cable Vol 2&3 to Lugs 1&2 so the max Vol was fully clockwise. But this is my first build and I was assuming Lug 1 is LHS.

I found some other schematics that cleared that up for me. 150k is not connected to both the B & E of that transistor and so on. I'm use to seeing a curve in the line if it's not really connected at that point. Either way, I tried all of the corrections out before I made the jumpers and it's still not working. It has to be really close to a working layout, but something is still wrong with mine.Anonymoushttps://www.blogger.com/profile/07149040853254697726noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-39300482832526976012017-11-25T17:54:09.134+00:002017-11-25T17:54:09.134+00:00The 1M is a pull down resistor to prevent switch p...The 1M is a pull down resistor to prevent switch pop and was not on the original, it won't cause any issues. The thing is I see what you're talking about. The problem is that connections in a schematic are usually shown with dots between components if lines goes through each other rather than have a hump showing they're not connected. It could be that wherever lines intersect are connected, but not quite sure with this one. You can try to make those connections and see if that brings it to life.

I studied the schematic for long time after that, and thought I'd found other problems with the layout above, but they didn't end up fixing it either. There seemed to be at least 3 places around the transistors that needed to be jumpered, if you follow the schematic. Such as the 150K resistor near the input is connected to both the B & E of that first transistor, but not in the layout above. The other two transistors have a similar disconnection, if I'm correct about interpreting the schematic. I don't see the 1m resistor anywhere in the beginning of the schematic either.<br />https://www.element14.com/community/blogs/andybetts/2017/09/01/colorsound-power-boost-18v Anonymoushttps://www.blogger.com/profile/07149040853254697726noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-27946672685729484262017-11-13T09:58:23.623+00:002017-11-13T09:58:23.623+00:00Thanks guys for clarifying this , Cant wait to bui...Thanks guys for clarifying this , Cant wait to build it , I was well impressed with the Colour Sound Overdrive to think that was only 9v yet the sound was huge.
