So im building a zendrive clone and it calls for a 2M2 resistor. I ordered from the pedalpartsplus a 2.2M resistor. Its the same thing correct?

yep!

Pretty much whenever you see a letter between two numbers in resistor values the letter is replacing the decimal point.

2M2 = 2.2M ohms
4k7 = 4.7k ohms
3r3 = 3.3 ohms

The reason for the letter in place of the decimal is because in the past, printers sometimes didn't print the decimal. So when the schematic was scanned or copied, it didn't show up, and it caused problems.

These days, the technology is much better for scanning/copying/printing, but the convention is still used by some people. I have mainly seen this on schematics from Europe. Not so much in the USA except for smaller builders.

It's the same... where in the circuit does it call for the resistor? If you can't find a 2.2M you might be able to sub a different value in (if it's an anti-"pop" pull down for instance).
