Vintage fuzz on "space" transistors

[Start]

Hi,

I will sell a fuzz effect pedal on Soviet ?403A germanium transistors. These transistors were developed in 1957 and were used in various special equipment, for example, in Sputnik-3 and the Gagarin rocket (details here: ?401-?403 - ????? ??????????? ????????? ).
The circuit is based on Fuzz-Face, but a preamp has been added. This increased the sensitivity.
Condition - 100% brand new. The price is $110 (the post shipping is included in the price itself).
About the purchase, write to my Instagram: @start_preamps
