CT-Fend312EMFDS-4217B.wav

Inspired by Fender® 3x12

Name decoding:

  • CT → Choptones
  • Fend → cabinet Fender-style (American clean)
  • 312 → checkout 3x12” (rare configuration, very wide)
  • EMFDS → specific voicing (typically:
  • Eminence / Fender Deluxe / Super-type character
  • → sound American, open, very dynamic)
  • 4217B → microphone/position combination:
  • 421 → Sennheiser MD421 (body, low-mid)
  • 7B → Choptones variant (position/mix → often more “ambient/room-like”)

Sound character

This IR is very “amp in the room”:

  • low wide but soft
  • natural mediums
  • high brilliants but not aggressive
  • great spatiality

Result: open, three-dimensional, very realistic sound

Perfect for:

  • clean Fender
  • ambient
  • blues
  • country
  • funk
  • natural recordings

Recommended Parameters

Gain (dB)

IR level

Very dynamic IR → DO NOT compress

Examples:

  • Clean: -3 dB
  • Funk: -4 dB
  • Environment: -4 / -5 dB

Rule: Maintain headroom for dynamics

HiCut (Hz)

Cuts high frequencies

IR Fender → brilliant → important parameter

Realistic range:

  • 5 kHz → 8 kHz

Examples:

  • Clean hot: 5.5 kHz
  • Funk: 6.5–7 kHz
  • Environment: 6–6.5 kHz

Rule: too high = punchy sound too low = you lose sparkle

LoCut (Hz)

Cuts low frequencies

3x12 open-style → wide bass

Realistic range:

  • 80Hz → 120Hz

Examples:

  • Clean: 80 Hz
  • Funk: 90 Hz
  • Environment: 85–95 Hz

Rule: Avoid “boominess”

Mix (%)

Blend IR / dry

Standard:

  • 100%

Creative:

  • 80–90% for ambient

Pro Tips

Great starting point:

  • Gain: -4 dB
  • HiCut: 6–6.5 kHz
  • LoCut: 85–90 Hz
  • Mixes: 100%

This IR is more “ambient” (7B):

less direct, more space, less need for reverb

CT-Fend312EMFDS-4217B is perfect:

for realistic cleans for direct recording for ambient for wide stereo
