Flathill Studio 412 (TL)

Inspired by Mesa Boogie® Studio 4x12 (Top-Left Speaker)
4x12" Speaker

4x12 closed-back modern font:

  • tight low-end (TL)
  • refined answer (Study)
  • less harsh than normal TL
  • more controlled than the BR
  • in practice it is the closest to a modern “mix-ready” IR

Controls

Gain (dB)

Mic volume

  • ↑ more output
  • ↓ more headroom
Mic Dist (inch)

Microphone distance.

  • 0–1” → ultra tight
  • 1–3” → balanced
  • 3–5” → more air
  • here -> more manageable distance than normal TL less loss of definition
Mic Axis (On/Off)
  • ON → attack
  • OFF → smooth
  • here -> ON less aggressive OFF very musical
Low (dB)
  • negative → super tight
  • positive → more body
  • already checked -> small adjustments are enough
High (dB)
  • negative → less fizz
  • positive → more air
  • here -> you can boost digital harsh without problems
Delay (ms)

Signal delay.

  • 0 ms → direct
  • 1–5 ms → depth
  • 5 ms → clear phase
  • useful for -> simulating multi-mic studio
Ambience (Y/N)
  • OFF → close mic
  • ON → advanced simulated environment
Amb Level (dB)

Room volume.

  • low → realistic study
  • high → ambient
Amb Size (ms)

Room size.

  • 20–40 → tight room
  • 40–80 → study
  • 80–120 → large

more believable than normal TL

Suggested Microphones

Identical list, but here you have the most "universal" rendering.

  • SM57 → more controlled, less harsh
  • MD421 (all) → very full
  • SM7 (variants) → perfect modern leads
  • Rezio → one of the best on this cab

this cab: makes the dynamics more “finishing-ready” with less need for corrective EQ

here: super natural, excellent for virtual blending

KEY DIFFERENCE: here you can use condenser even on high gain which is difficult on other 4x12s
