What's this spy recorder inside the pedal ? :secret:
Is the RIAA aware of that ?

Seriously, it's an amazing thing, PTP-wired with insulation on each component lead, tube-driven cassette-deck tape echo ! One thing that i still don't get, is what you do when the tape ends ? it doesn't look like a tape loop, and the cassette is not removable :scratch:
I only give negative feedback.

A part of the cassette is hidden by the edge of the pedal, so it could be a tape loop like those dictaphone tapes used in the Univox/Melos/Monacor tape echo machines where the tape is pulled from the middle of the roll while it's winded on the outside.

Perhaps these pics indicate a little more...

I've never heard one or seen one for that matter.

What do you suppose those dealy-bobs taped tp the cassette's body are?
This thing's construction/parts count makes the Cornish & Skyrdstruup[sp?] boxes look like
re-housed delay pedals. :shock:

Oh yeah, they are. :secret:

I'm sorry, my link apparently used your photos DiscoFreq. :oops:

I still want to know more about it's operation if nothing else.
