One Knob Fuzz Transistors

Hi GB&C,
I am looking into building a one knob fuzz for a little multi fx project, but my store (and actually the only decent parts store here) does not stock a BC108 transistor seen in the original schematic. It does however stock BC107B, BC107C and BC109, and an awfull lot of others. Do you have any recommendation on using a transistor instead of the BC108? Thanks in advance

According the 108 data sheet the 107 series are PNP, not NPN, so you would after to adjust accordingly, but it doesn't mention the 109. Why not just order from amazon?

Almost any small NPN will do. BC109 will be fine.
