Physical model parameter optimisation for calibrated emulation of the Dallas Rangemaster Treble Booster guitar pedal

In this work we explore optimising parameters of a physical circuit model relative to input/output measurements, using the Dallas Rangemaster Treble Booster as a case study. A hybrid metaheuristic/gradient descent algorithm is implemented, where the initial parameter sets for the optimisation are informed by nominal values from schematics and datasheets. Sensitivity analysis is used to screen parameters, which informs a study of the optimisation algorithm against model complexity by fixing parameters. The results of the optimisation show a significant increase in the accuracy of model behaviour, but also highlight several key issues regarding the recovery of parameters.

"I Forbid You To Like It:" The Smiths, David Cameron, and the Politics of (Mis)appropriating Popular Culture

The Smiths were a critically acclaimed 1980s “indie” band that achieved cult-status within the five years they were musically active. Several studies on fandom have focused on The Smiths, particularly its frontman Morrissey, whose “apostles” are among the most committed on the popular music circuit. Yet British Prime Minister David Cameron’s repeated claims to Smiths fandom have been rebuked by fans, and the band themselves, as being incompatible with his right-wing political program; former Smiths guitarist and songwriter Johnny Marr tweeted: “David Cameron, stop saying you like The Smiths, no you don’t. I forbid you to like it.”

This article proceeds from the possibility that David Cameron was not being cynical in professing his admiration for The Smiths and considers music’s role in the embodiment of a social identity. Drawing on recent examples in the UK and the US, the article explores politicians’ problematic relationship with popular culture, alongside the notion that when an artist’s music is appropriated, they themselves are appropriated.
