Was there ever a book or instructions on how Laurie Anderson built hers? I see a few diagrams online and definitely a bridge on each side of the tape head for alignment.<div><br></div><div>Kylee<br><br>On Sunday, April 29, 2018, Phillip Gallo <<a href="mailto:philgallo@gmail.com">philgallo@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><div><div><div><div><div><div><div><div><div>Sounds like a fun project.<br><br></div>The fidelity of playback audio depends in a major way upon:<br></div>-Playback vs. original recording rate of travel for the tape,<br></div>-Matching alignment of tape orientation for record/playback,<br></div>-Degree of intimacy between tape and and tape head gap.<br><br></div>Would seem to me the bow methodology frustrates all the above but most likely in an interesting and highly listenable way.<br><br></div>As to tape head it would be my guess that a Full-Track Mono playback head would be the best solution to reduce output variation due to tape orientation.<br></div><div>I doubt a transcription quality head vs. a commercial audio head would provide much difference and mono heads in the transcription arena are easier to source.<br></div><div>I've assumed you are using a 1/4" tape format due to your mention of Reel to Reel.<br></div><div><br></div>I had the thought that if you record with a stereo format that differing angular approaches to the mono head could vary well result in interesting timbral change, at least to some degree.<br><br></div>The speed of the recorded material vs. playback rate would seem to be an interesting issue.

Since you have a variable rate for tape movement it could be that just compensating for the head response, rolling off high end at a frequency you just might empirically determine, is the way to go.<br><br></div>Lots of opportunities for fun!
