Selmer Buzz-Tone

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 ๐Ÿ‘๐Ÿฟ.

Hohner Basset

When i bought it it looked like this


I opened it up to clean it and realised this wasnt its original colour.


It really was taupe gray before, but the years had the plastic chassis yellowing

I decided to restore it to its original colour (or as close as i could…)

After 5 months of great fun, I had to open it up because the output went silent.

Gutshots of the Hohner Basset!

Lets start with the DIN jack that connects it to the bass amp..

Keyboard:

Circuit board and caps jungle:

Inside the white enclosure there’s a lamp and a ldr.. this assembly is the actual “percussion” section.

You press a note on the keyboard, the light goes off slowly (sustain) according to the knob position, when not in auto mode.

Video below..

Pcb: 3.1967!!

Ahem this means the caps have been doing their job for 50 long years! Only one of the capacitors has failed, please note- the blue valvo 100uF cap now measures 1uF!

Output DIN and 3 pronged jack, fuse

Hohner Cembalet repair

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):

Hohner Cembalet User Manual with schematic

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.

Electro Harmonix Vintage Black Fingerย 

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.

Maestro FZ-1a Fuzz Tone

dates about 1966-67

 

maestro+epi casino=garage!

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.
