Extremely rare!! Some consider it to be the best Muff variant ever made (agreed fully!!)

No box but I will ship it in an wood EH Big Muff box.

THE HOHNER TRI DIRTY BOOSTER BIG MUFF CLONE

Circa 1973-76
Manufacturer: Unknown
Place of Manufacture: USA

In the mid 1970s an exceptionally good sounding Big Muff clone appeared on the market in the USA, the Hohner Tri Dirty Booster. The Tri stood for Triangle, as the V1 Big Muff had come to be known due to the triangular knob layout. Hohner had been around since 1857, known as one of the worlds largest accordion and harmonica manufacturers. Hohner branched into making keyboards in the 1940s, electric guitars in the 1950s, and acoustic guitars in the 1970s. As many other companies were doing at the time, Hohner also branched into the effect pedal business in the mid 1970s. These included the Sound Modifier Series, the Dirty Booster Overdrive, and the Tri Dirty Booster, which was essentially a straight clone of an early Big Muff with an extra capacitor in the tone section. The circuit was likely cloned from one example of a V1 Big Muff, though the particular circuit copied had a very good set of component values. The Hohner TDB sounds superb and rivals the best examples of the real V1 Big Muffs. I have seen a few examples of these with slightly different capacitor values, but overall they seem to be identical. Most have a 470pF cap in the first stage, and 500pF caps the two gain stages. The extra cap in the tone section is a bit of a mystery. I assime it was added to alter the tone range on the bass side, but I cannot hear much of a difference with or without it.

At first glance this almost appears to be an OEM version of the V1, but this was not made by Electro-Harmonix. The manufacturer Hohner contracted to make these pedals is unknown, but it was made in the USA. The enclosure is identical to the rare Rogue Fuzz, from around 1973, so this appears to have been made by the same factory. It is possibly the same factory that made the Guild FW-3 and Goya Fury Box.
