These LADSPA plugins, accompanied by some blurbs about motivation and
approach, mostly centered around (but not in the least confined to)
digital guitarist needs.

'super-60' is another effort to recreate the physical and electronic
spectral effects of an electric instrument amplifier, applying the
same methods as the predating 'unmatched' project. In short, it makes
a signal sound very much like it went through Fender Super 60 amp, bar
nonlinear effects and intra-cabinet reflection. Unlike traditional
convolution methods, it employs a 16th order IIR filter to emulate a
pre-recorded impulse response, resulting in realtime-compatible CPU
usage figures (4-8% on a ~500 MHz box).
