Headrush Wah & Filter
Tron Filter
Inspired by Mu-Tron® III Envelope Filter
Filter inspired by the classic Mu-Tron / analog envelope filters combines:
- resonant filter
- dynamic modulation (envelope)
- vintage/funky character
GENERAL FUNCTION
- Dynamic filter controlled by signal dynamics (like Env Filter)
- but with more controls (freq, resonance, depth etc.)
It produces:
- auto-wah funk
- synth-like
- vocal effects
Control Parameters
Base FrequencyHz
Filter starting frequency
- low → dark sound
- medium → funk zone
- high → brilliant
It is the "zero point" from which the movement starts
Resonance%
Emphasizes the filter frequency
- low → soft
- medium → natural wah
- high → very pronounced effect
Fundamental to “quack” funk
Fatness%
Adds body/bass
- 0% → thin
- high → full
Useful to avoid sounds that are too thin
Modes
- 24 dB: Very steep low-pass modern/synth sound
- 18 dB: balance between soft and defined
- 12 dB: more natural
- BP (Band Pass): only one band passes (classic wah effect)
- HP (High Pass): low cut (thin / funky sound)
Depth%
Modulation intensity
- low → light movement
- high → wide sweep
Equivalent of the Range in the Env Filter
Mix%
Dry/wet blend
- 0%: dry
- 50%: parallel
- 100%: full effect
GaindB
- Output volume
Compensates for variations
Pro Tips
- high resonance → acidic sound
- depth high → very evident effect
- BP mode → more wah
- HP mode → less body
Perfect funk setup:
- Mode: BP
- Resonance: high
- Depth: medium-high
Add:
- compressor first → smoother response
Quick Reference
- Base Frequency: filter base point
- Resonance: emphasis
- Fatness: body
- Modes: filter type
- Depth: movement intensity
- Mixes: blend
