Chinese Forehead made use of assorted low-tech gear for a variety of effects. In addition to the use of a [[vibrator]], a hacked open-reel tape recorder was used to run tape loops. | Chinese Forehead made use of assorted low-tech gear for a variety of effects.

+ | The device was pulled from some street-side trash one day. You can kinda-sorta see a picture of it in one of the [[posters]] for the [[1979nov15tr3|Nov 15 1979 TR3 ]] gig. | ||

+ | It looked somewhat similar to this image: | ||

+ | It was big, clunky, and fun to hack. | ||
+ | |||
+ | Such devices work by altering magnetic tape as it passes over the tape head assembly. On this device the record head preceded the play-back head. If you sent an audio signal directly to the record head the sound would be recorded on the tape and immediately played by the playback head. | ||
+ | |||
+ | One result was a cheap, short, delay. | ||
+ | |||
+ | If you did not send any audio signal whatever was on the tape would play. By using lops of various sizes in place of the standard reels a section of sound could be repeated endlessly. | ||
+ | |||
+ | To provide a signal, an electric guitar (a 1976 [[http://www.fender.com/guitars/stratocaster/|Fender Stratocaster]]) was run through a [[http://www.amazon.com/Pignose-7-100-Legendary-portable-amplifier/dp/B0002D0JZ6|Pignose Amp]]. However, instead of outputting to the speaker, the speaker wires were re-routed to run to the record head for the tape loop. | ||
+ | |||
+ | The loop was used for some performances of the [[b_song|B Song]] and [[Altitude]]. | ||
+ | |||
+ | Live use was discontinued because the set-up was prone to failure at just the wrong moment. | ||
