I would have built myself a Metalzone, but after seeing how complex the schematic was(and I did manage to find a hand-drawn schematic online), I decided that it would be easier to just buy one, it's a bit too complex to lay it out on a bit of Vero board, and some of the parts need to be matched for parts of the circuit to operate properly, plus the cost of parts probably would have equaled what I paid for the new pedal, this is a case where sometimes it's un-economical to make them yourself.
On the other hand, a Vintage Fuzz Face pedal would be a more economical pedal to make, since it is a much simpler circuit, the cost in parts would be much lower (a Vintage Fuzz Face could cost anywhere from $800.00 to $1000.00 or more considering that it uses maybe $50.00 worth of parts), and it is hard to find a good sounding Vintage Fuzz Face pedal since they vary a lot, some don't even work unless repair work is done on them.
I did have a decent think about it, but I came to the conclusion that it would work out cheaper to buy one rather than to build one, the circuit of my Baja Real Tube Overdrive pedal is easier to build compared to the Metalzone, and it probably cost me around $60.00 in parts alone, plus another $30.00 for the set of professionally etched circuit boards.
But you're right, Wokka, I should also be putting some money aside for when it comes time to do the move, it looks like it's going to be some time till I actually end up doing it though.
