Virtually all overdrive pedals use some form of bass cut before distortion, and treble cut after distortion. The bass cut pushes the mids to saturate & drive first, which keeps the bottom end tight & punchy. The treble cut smooths out distortion artifacts (like fizz). The Dragon puts the precise amount of each of these cuts in your hands, and combines them with a dynamic drive engine. This lets you tailor the saturation point to your ear & gear, while preserving dynamic sensitivity - and it can get LOUD!
- HPF sets the cutoff frequency of the high-pass filter (bass cut). A higher frequency setting results in a more aggressive bass cut.
- LPF sets the cutoff frequency of the low-pass filter (treble cut). A higher frequency setting results in a less treble cut.
- The LEVEL control is passive, and is designed to cut the volume of the massive gain stage to reasonable levels...or you can crank it up and wake your neighbors.
- GAIN sets the amount of gain in the drive circuitry. More gain = more distortion/saturation = more overall volume.
- The 6dB / 12dB switch sets the slope of each filter. For example, setting the HPF at 400Hz in the 12dB position, the frequency response would be -12dB @ 400Hz, -24dB @ 200Hz, -36dB @ 100Hz, etc.
- The "secret" center position of the toggle switch combines a 12dB/octave high pass filter with a 6dB/octave low pass filter.
