Inspired by Bogner® 4x12

Name decoding:

  • CT → Choptones
  • Bogna → cabinet Bogner-style 4x12
  • 412 → checkout 4x12”
  • V30T75 → speaker mix:
  • Celestion Vintage 30 (V30) → aggressive mids, punch
  • Celestion G12T-75 (T75) → deep bass, extended highs
  • 57421 → microphone combination:
  • 57 → Shure SM57 (attack, mid focus)
  • 421 → Sennheiser MD421 (body, low-mid)

Sound character

This IR is a classic “modern pro mix”:

  • low deep but controllable
  • medium present (V30)
  • high definition (T75 + SM57)
  • very fast attack

Result: aggressive, wide, modern and mix-ready sound

Perfect for:

  • modern metal
  • hard rock
  • djent
  • powerful rhythms
  • professional recordings

Recommended Parameters

Gain (dB)

IR level

Very full IR → pay attention to gain

Examples:

  • Rock: -6 dB
  • Metal: -8 dB
  • Djent: -9 / -11 dB

Rule: more amp gain = less IR gain

HiCut (Hz)

Cuts high frequencies

SM57 + T75 → possible harsh on the highs

Realistic range:

  • 6 kHz → 8.5 kHz

Examples:

  • Rock: 6.5 kHz
  • Metal: 7–7.5 kHz
  • Djent: 7.5–8 kHz

Rule: Control fizz without losing definition

LoCut (Hz)

Cuts low frequencies

T75 → wider bass → CRUCIAL parameter

Realistic range:

  • 100Hz → 150Hz

Examples:

  • Rock: 110 Hz
  • Metal: 120–130 Hz
  • Djent: 130–150 Hz

Rule: more LoCut = tighter less LoCut = more “wall”

Mix (%)

Blend IR / dry

Standard:

  • 100%

Creative:

  • 80–90% for ambient

Pro Tips

Great starting point:

  • Gain: -8 dB
  • HiCut: 7 kHz
  • LoCut: 120–130 Hz
  • Mixes: 100%

This IR is already “mixed” (57 + 421)

great on its own less need for EQ perfect for direct tracking

CT-Bogna412V30T75-57421 is perfect:

as main IR for metal for double stereo tracks for powerful live performances in combination with smoother IR
