This is my first instructable, so please be kind. I found an instructable a while ago that spoke of a passive overdrive - black ice. This can be bought for extortionate prices, but somebody found out that it was only really worth about £1.20 (that's about $2!) The company were making a 1400% profit!

It has got better, however, with a slightly more complex circuit and various ways to wire it. I don't know how they do it (I don't know a great deal about electronics), but I have found a way to make it into a pedal with true bypass. Yes, TRUE BYPASS! (the ones on the black ice website don't have true bypass)

I wired the original black ice, but you can use JoeBeau's rectifier with a different way of wiring it. I have got a theory on how to wire it like this, but I haven't tried it, so please correct me in the comments if I'm wrong.

I got help from:

Let's get started!

Step 1: Tools and Materials

Tools

- soldering iron and solder
- drill
- wire cutters, pliers etc - whatever you can use to help (e.g, I used a screwdriver to bend the leads and from the diodes around lugs)
- marker pen (for decoration!)

Materials

- project box
- DPDT switch
- 250k pot (I'm not sure whether I used linear or audio taper and I can't be bothered to check - it doesn't really matter)
- 2 x 1/4 inch output jacks
- 2 or 4 x 1N5818 Schottky diodes (I forgot to thank this guy for which diode to use - I wasn't going to keep buying diodes until I found a good one!)
- some wire

Bio: I never learned how to solder properly, everything I make turns out to look shabby, but it works. Usually.
