One coil is the sensor coil; it senses the movement of the nearby string as the string vibrates. This signal is sent to a small amplifier housed within the Ebow, powered by a 9-volt battery. The amplified signal is sent to the other coil, called the driver coil. The driver coil puts out the signal in the form of an oscillating magnetic field, which magnetically reinforces and perpetuates the motion of the nearby string. If the Ebow's driver coil is in close proximity to the guitar's own pickup, the output signal also feeds directly into the pickup." - [[202306251948 Hopkin & Landman 2014 Nice Noise]], p. 53. ## Assemblages - [[202304031205 Assemblage B.F1.45.56]] - [[202307052213 Assemblage B.F1.21.56.92]] - [[202307101344 Assemblage A.B.F1.F1.14.23.56.80.89]] - [[202307151852 Assemblage A.B.F1.F1.56.89.92.93]] - [[202307231815 Assemblage B.F1.56.95]] ## Open questions - How do I destabilize the e-bow? - [[202204072145 Object 56 (E-bow)]] + [[202209071143 Object 79 (Snare Drum Wire)]] - [[202307231815 Assemblage B.F1.56.95]] - [[202307052213 Assemblage B.F1.21.56.92]] - [[202307151852 Assemblage A.B.F1.F1.56.89.92.93]] - [[202307101344 Assemblage A.B.F1.F1.14.23.56.80.89]] ## Workshop notes - [[2022-12-03]] - [[202204072145 Object 56 (E-bow)]] + [[202209071143 Object 79 (Snare Drum Wire)]] also work when put on the string of the guitar. - This gives a very unpredictable, self-perpetuating feedback sound that is highly varied. - Something like this could be a concert/piece in itself. Just the [[202204072145 Object 56 (E-bow)]] and [[202209071143 Object 79 (Snare Drum Wire)]]. Moving them and searching for different sounds in this constellation of objects. - [[2023-01-31]] - Use the [[202209071143 Object 79 (Snare Drum Wire)]] or [[202212111232 Object 81 (Clipped Snare Drum Wire)]] underneath the [[202202032052 E (Mobile pickup)]] with the [[202204072145 Object 56 (E-bow)]] to get a super unpredictable and rich sound. - [[2023-04-03]] [[202304031205 Assemblage B.F1.45.56]] [[202304031144 Recording B.F1.45.56]] | Place [[202304021729 Object 45 (Glockenspiel Bars)]] (pitch: C) on the strings of the [[202204092206 B (12-string object guitar)]]. Use [[202204072145 Object 56 (E-bow)]] to excite the B/2nd string pair and use the fingers to apply pressure to [[202304021729 Object 45 (Glockenspiel Bars)]]. - [[2023-07-05]] [[202307052213 Assemblage B.F1.21.56.92]] | Use [[202204072145 Object 56 (E-bow)]] as a boost/overdrive and to accentuate harmonics. Hover [[202204072145 Object 56 (E-bow)]] over one of the pickups. When the string is muted, the e-bow will not sustain the note, but just act as an amplifier for that specific string. - Because of the gain increase, there is also a large increase in background noise that can be used. - [[2023-07-23]] [[202307231815 Assemblage B.F1.56.95]] | There is an emerging rhythmic pattern that changes when sliding [[202307212013 Object 95 (Broche)]] along the [[202204092206 B (12-string object guitar)]] while [[202204072145 Object 56 (E-bow)]] is exciting it. The pattern seems to get faster when moving [[202307212013 Object 95 (Broche)]] closer to the end of the strings. ## History - The first electrified guitar used a similar mechanism as the e-bow.[^1] - [[202204072144 David Stackenäs]] - [[202306101552 Stackenäs 2011 David Stackenäs solo at Inage Candy]] - [[202109251204 Keith Rowe]] - [[@vandaaleKeithRoweLive2008]] - [[Frengel 2017 The Unorthodox Guitar]], p. 76 - [[202306251948 Hopkin & Landman 2014 Nice Noise]], p. 53 - "The Ebow does what it does by means of a pair of electromagnetic coils, similar to the coil of a magnetic guitar pickup.
