Electro Harmonix Vintage Black Finger 

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.

Dynacord EC280

Was this the very first BBD delay? 

 
Tabletop machine, self oscillating AND from past internet auctions and reviews it is apparent, nobody knows how to determine if theirs is in working order (😂), because it is very temperamental and does a lot of different things.. But when it behaves, it’s magic!

Echo, reverb and has a very weird chorus.

Amazing and beautiful, nothing like a tape echo or a memory man.. Far less predictable!

A delay with character.
