Electro HarmonixLumberjack Log Overdrive

Electro-Harmonix has room to experiment with the Lumberjack’s overdrive function, and they certainly do. The Lumberjack’s response is based on a logarithmic curve (rather than a linear one) and the change between two values is perceived as a ratio of those values. Therefore, a change from 1 to 2 (ratio 1:2) is perceived as the same as a change from 4 to 8 (ratio of 1:2). This keeps the overdrive nice and responsive to input dynamics and offers a huge range of fuzzy boosts to mess around with.
