From the post

For Fuzz Friday we have the original Swollen Pickle from Way Huge Electronics. One of the unique things about this Muff clone is the use of a quad transistor array instead of 4 individual transistors. This makes for a quieter pedal and more consistency in transistor matching. However if you don't feel like tracking down an MPQ3904 or NTE2321, you can use 4 individual transistors. Just note the pinout in the layout below.
