Investigating the effect of body geometry on the acoustics of electric guitars
Bibliographic record
Abstract
Three electric guitars of different body geometries are investigated in an attempt to characterize their tonal differences. One guitar has a solid body, one is fully hollow, and one is semi-hollow which represents a midway point between the first two. The transfer functions of the electromagnetic pickups are determined by inducing a known signal through the pickup and measuring the output. Input admittance measurements are taken at the bridge and nut of each guitar to show the vibrational modes of the bodies. Wire break measurements are taken for different notes on each guitar, which are analyzed in conjunction with the admittance measurements. The results demonstrate significant admittance peaks in the hollow and semi-hollow guitars that are not present in solid body electric guitars. As well, “dead” notes with shorter decay times are found to be correlated with these admittance peaks, thus indicating that the bodies of hollow and semi-hollow electric guitars play a role in their tonal characteristics.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
