Muffin and Mini-Muffin are fine projects to build all the known variations of the Big Muff(TM).
While the Muffin is ideal for a 1590B enclosure…
…the Mini-Muffin fits a 1590A enclosure.
Please note that despite its size all resistors are 1/4 W size!
You are able to build a lot of different versions as shown here: http://juansolo.co.uk/stompage/Muffs.htm
