Headrush Impulse Responses
Jr112
Inspired by Fender® 1x12
Typical interpretation:
- Jr → reference to Fender Blues Junior (famous tube combo)
- 112 → checkout 1x12”
Sound character
This IR is very “amp-like” and natural:
- warm and present mids
- high soft (not aggressive)
- controlled bass
- dynamic response
Perfect for:
- blues
- clean / crunch
- country
- light rock
- expressive leads
Recommended Parameters
Gain (dB)
Controls the IR level
Very natural IR → it's no use lower too much
Examples:
- Clean: -3 dB
- Blues: -4 dB
- Crunches: -5 / -6 dB
Rule: Maintain dynamics and touch response
HiCut (Hz)
Cuts high frequencies
Jr112 has soft highs → don't overdo it
Realistic range:
- 5 kHz → 8 kHz
Examples:
- Clean: 6 kHz
- Blues: 6.5 kHz
- Crunches: 7 kHz
Rule: too low = dull sound too high = you lose naturalness
LoCut (Hz)
Cuts low frequencies
bass already checked → moderate use
Realistic range:
- 70Hz → 110Hz
Examples:
- Clean: 80 Hz
- Blues: 90 Hz
- Crunches: 100 Hz
Rule: maintains clarity without taking away body
Mix (%)
Blend IR / dry
Standard:
- 100%
Creative:
- 80–90% for ambient sounds
Pro Tips
Great starting point:
- Gain: -4 dB
- HiCut: 6.5 kHz
- LoCut: 90 Hz
- Mixes: 100%
If the sound is:
- too dark → raise HiCut
- too thin → lower LoCut
- not very dynamic → lower Gain
- too “flat” → increases HiCut slightly
Jr112 works great:
with Fender-style amp for direct recording with overdrive pedals as a neutral base for effects
