Assessment

Analyse, then manipulate, then design

Three assessments, each building on the last — analyse a recorded guitar tone, manipulate a signal chain with pedal-style processing, then design a complete chain from a target sound. Every assessment may only assume material the course has already covered by its due date. Together they sum to 100% of the final grade.

The three assessments

Stage 1 Analyse

Tone Autopsy

Analyse an existing guitar sound using only what the first four weeks have covered — and say which of your claims are evidence and which are guesses.

  • Observation and use of evidence25%
  • Spectral and physical reasoning35%
  • Separating observation, interpretation, and assumption20%
  • Clarity of technical explanation20%

Stage 2 Manipulate

Pedal Laboratory

Change one or more variables in a simplified nonlinear pedal model, and trace the full chain from parameter change to audible consequence.

Stage 3 Design

Engineer a Guitar Tone

Design and justify a complete guitar-tone signal chain for a stated target sound, using the course's principles rather than "it sounds better".

Assessed as one integrated piece of work rather than a checklist of separate marks: does the chosen signal chain plausibly achieve the stated target, does every major decision carry a justification grounded in a course principle rather than taste, does the response show it understands how stages interact (not just what each stage does alone), and does it name at least one real trade-off the design accepts. A chain with a weaker overall design but stronger, more specific justification at every stage will mark higher than a plausible-sounding chain justified only by assertion.
