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 👍🏿.

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

Video showing the lamp going off when a note is keyed.

Selmer Buzz Tone

Syd Barrett’s hairy boost.. VERY WARM AND THICK. Perfect counterpart to Syd’s favourite amp settings, basically treble at 10. 

Perfunctory build on eyelet board, with external vero for transistor testing, using 2N2613 as per original.

Very surprised by the final tone, i really like it.. Sounds very nice.   
I broke out the wem copicat to have a better idea if it nails syd’s tone.
