From the vendor

Tim Escobedo's Tripple Fuzz, built around a 'nonselective frequency tripler' originally designed by R. Lockhart Jr.: an MPSA18 gain stage feeds a complementary 2N3906/2N3904 pair, followed by silicon diodes to ground. The drawing says it is sweet at low gain, an odd splatty fizz as the gain rises and nasty at full gain. The post shows it as the same tripler structure the Machine uses (and the Lovepedal Karl).
