Tangerine212OB

Inspired by Orange® 4x12 (Open Back)

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

Gain (dB)

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"

HiCut (Hz)

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

LoCut (Hz)

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

Mix (%)

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

Tangerine412OB is perfect:

in stereo with a 4x12 closed for “amp in the room” sounds with delay and reverb for natural recordings
