Tangerine212OB
Typical interpretation:
- Tangerines → cabinet style Orange (British brand)
- 412 → checkout 4x12”
- OB (Open Back) → open back
Sound character
This IR is very particular because it combines:
- 4x12 punch
- opening and air from open back
- warm and present mids
- high soft (not sharp)
Result: wide, three-dimensional sound, less "tight" than a closed back
Perfect for:
- alternative rock
- indie
- blues rock
- ambient
- dynamic crunch
Recommended Parameters
IR level
Open back = less compression → leaves more dynamics
Examples:
- Clean: -4 dB
- Crunches: -5 / -6 dB
- Rock: -6 / -7 dB
Rule: don't raise it too much to maintain "air"
Cuts high frequencies
this IR is already soft → don't overdo it
Realistic range:
- 5 kHz → 8 kHz
Examples:
- Clean: 5.5 kHz
- Indies: 6–6.5 kHz
- Rock: 6.5–7 kHz
Rule: too low = closed sound too high = you lose vintage Orange character
Cuts low frequencies
Open back = less controlled bass
Realistic range:
- 80Hz → 140Hz
Examples:
- Clean: 90 Hz
- Indies: 100 Hz
- Rock: 110–120 Hz
Rule: fundamental to avoid “flubby” sound
Blend IR / dry
Standard:
- 100%
Creative:
- 80–90% for ambient
Pro Tips
Great starting point:
- Gain: -5 dB
- HiCut: 6.5 kHz
- LoCut: 100–110 Hz
- Mixes: 100%
If the sound is:
- too “loose” → raise LoCut
- too “closed” → raise HiCut
- little present → lowers LoCut
- not very dynamic → lower Gain
