Hoping to contact Geek with this but anyone is invited to chime in.
I found the following link in the archives to this forum:

This "test jig" looks really kool to me -- think I might build one. This thread links to another thread where details about incorporating the 6jt8-based reverb loop into an amp is located.
Unfortunately, that link is dead. Perhaps a victim of the Tone Geek site crash a while ago. Could this topic be discussed again? thx.
