I have been building Selmer Buzz Tones for a few groupies n fans recently.
Featuring original, near-impossible to source transistors, 2N2613 on choc brown paxoline board, on eyelets just like the original.
One small mod is the cap tuck away under the board, to give it some juice (otherwise it wont buzz!).
Cheapo build for a friend:
Another build.. featuring the Palenque astronaut..
Expensive nos carbon comp build for a groupie:
They all sound 👍🏿.
My beloved Hohner Cembalet I has gone silent, all of a sudden.
Here we go with a few pics i took for reference of the main board.
They may help someone else whos trying to fix his Cembalet.. I hope.
Schem and user manual (in kraut):

Update: the Cembalet healed itself and now it works great. I did not have to do anything to it, it just works again, magic, bang.
A friend who’s an electronic repairer said that the most important part to watch out for is the inductor (Spule in german), as it’s custom wound to specs for this instrument.
This must be a very early one, word has it that Jimi Hendrix
tried one of these boxes for its big muff-like forced sustain. It is one of the earliest electro harmonix effects.
It is powered by TWO 9v batteries and so much for it “being distortion free”, it is
very hissy and noisy, and colours the tone. The compression is VERY apparent and squashed.
Transistors: FS36999, the same as early 70’s Big Muffs.
The tube version Black Finger is a much different, more reliable and usable item.
dates about 1966-67
Well.. At last i can say it: my clone (see back pages/older posts) sounds GREAT. Against this original (2N2614 transistors), with little or no attack pot excursion, aka max it or it wont fuzz, my clone is a pot full of sweet spots. Maxed, it is plain evil. Compressed.
Comparison, original vs my clone:
Still, the original has got so much mojo.. Magic. I will not mod it to bias the transistors better. As the Poets said, THAT’S THE WAY IT’S GOT TO BE.
