Does anyone know the e-mail of Patrik Eriksson, the one who drew a schem of the Metal Zone, or know the source of the other MT-2 schem with the 4 sections, or have another schem or know anything about the pedal, because there are some differences between them and I would like to know the reasons, differnce in sound, etc., cause I want to build one.
You must be really bored! You can buy one for about $30-$50. used
A boss mt2 isn't really a good pedal to DIY.. high part count, even if you get rid of jfet switching in favour of true bypass. you could buy one used for much cheaper than it would cost to make one.
have a look here for ideas

I have been building my own pedals for about three years now. I wouldn't even think about trying to build a Metal Zone clone. It's a lot easier to just buy one. There is a lot of parts involved and it is packed in a small PCB. You might be better off just buying a used one off of ebay and tweaking it more to your liking.
I would buy one, but it´s not so cheap in my country, besides I like building effects and it makes it easier to make all the mods I want, if anyone has schems or knows about the circuit, please let me know.

OK, if you have a lot of time and patience, then check out this link:

Look under the BOSS section. There is one schematic is in two parts, and another in three parts with an apparent mod. I don't know if they are the same or if they are accurate or not. Best of luck. 8)
