Hello!
Guitar and Bass Guitar Effects are a fairly well-documented subject, with a plethora of material covering both empirical changes to tone as well as descriptions of how the altered sound is perceived by the ear.
However, more difficult to find are studies of the blending of effects, especially more than two.
Even more rare are such studies applied to bass guitar rather than guitar effects.
This project aims to address this area of acoustics with a look at the result of some popular bass effects combined and applied to a normal bass tone, explained with both measurable differences as well as descriptions of how the modified tone sounds to the human ear.
Since a list of every possible combination of effects would be utterly exhausting, I have chosen to go with three of some of the most popular effects- distortion, Auto-wah, and Chorus.
Constants
In order for the results of this experiment to be viable, as many factors as possible must be kept as constants throughout every test.
These factors are as follows:
- Bass Guitar Model- Ibanez GSR190
- Bass Guitar Tuning- Standard EADG
- Note Being Played- A2 (12th fret of A string)
- Play Style- Finger Picking
- Effect Pedal- ZOOM B1X Multi-Effects Pedal
- Signal Path- Guitar to pedal to Audacity (on laptop)
Clean Tone Data
To begin my study I will present the data for the "clean" tone, clean meaning free from any sort of alteration or distortion. These statistics will be the standard to which the other tones will be compared.
Clean Tone Empirical Data:
- Initial Frequency- 107Hz (A2)
- Initial Sound Intensity- -12.8dB
- Halving Time- 1.069s
These statistics will become more important as the altered sound grows farther and farther from the original tone.
