Welcome. I wanted to provide stripboard layouts I've made to help people new to electronics and even the more experienced get into different aspects of electronics.

I verify the layouts before I post them.

Blue Wizard Overdrive / Distortion Stripboard Veroboard Layout


This is the Blue Wizard - part of my "wizard" design series (Green Wizard HERE) - this is a very harmonic rich overdrive/distortion that uses 2 BC182L transistors (cause I have a load of them) - this is the same transistor used in the Brian May treble booster HERE

it has a bias pot onboard and I find it's best to adjust it till it sounds good to you.

anyway - below is a quick sound sample - the 1st bit is the gain all the way up and the 2nd bit is the gain half way up.

    This circuit design really sounds good. Well done!

    Paul - I got around to building this one this evening. It is one awesome circuit and LOUD too! I see this finding a perm home on my pedal board. I wanted to build the Green Wizard but since I am no fan of Ebay, finding the parts has been, well... Anyways - Thanks for the work you do!

      you can get the parts from other places like mouser and stuff - eBay is just where you can find parts cheapest (alot of the time)

    Pardon my ignorance, but would there be a way to add a volume/level control to this without changing the sound?

      Yeah - its pretty easy - you'll need to experiment with pot values but this is pretty much it...

      Volume pot lug 1: Connect to to ground
      Volume pot lug 2: This is your NEW output
      Volume pot lug 3: Take the output wire from the circuit and connect it here

    It looks like the BC182L is pretty close to a 2n3904 (which I have a ton of ). Will those work in the circuit? (I know, the pinout is reversed between the BC182 and 2N3904)

      the 2n3904 will work but it has a much lower gain - a closer substitute would be the 2N5088
      but it's worth a shot with the 2N3904 - you never know, you might love it

    nice sounding overdrive!
    i did mine with 2N2219 (to-39 is more suitable for leg twisting).
    i got one question: would it make sense to socket the input cap? do different caps have an impact to the over-driven sounds?

    Hi!, what software are you using to design your stripboard layouts?
    Thank in advance, and congratulations for this goos stuff.

      thanks dude - there's a link to the software I use on the "tips and troubleshooting" page

    Im not very good at this, hence the (maybe) stupid question. But what is the orientation of the capacitors? as in where do i place the + or the - side..

      for every electrolytic capacitor on the cirquit C2, C7, C4 , minus(-) side points to the bottom of the veroboard.

    Hi. Slightly confused. How to I wire up the pot. Is 1 and 2 to ground ? Where does three go to E
