Flathill Studio 412 (BR)
Inspired by Mesa Boogie® Studio 4x12 (Bottom-Right
4x12" Speaker
Still a 4x12 British (Marshall-style) but in a “studio-enhanced” version
It means:
- more answer refined / controlled
- less harsh than the other Flathills
- more ready for recording
- It is NOT a true "Room cab" but has a more "studio" behavior (less raw)
Controls
Gain (dB)
Mic volume
- ↑ = more output
- ↓ = more headroom
Mic Dist (inch)
Microphone distance.
- 0–1” → direct
- 2–4” → natural
- 4–6” → more air
- DIFFERENCE -> This cab reacts better to more realistic distances by increasing distance
Mic Axis (On/Off)
- ON → bright
- OFF → softer
- here -> OFF is very musical ON less aggressive than angled
Low (dB)
- negative → tight
- positive → more body
- already balanced -> often 0 or small adjustments are enough
High (dB)
- negative → less harsh
- positive → more air
- here -> you can also increase without problems
Delay (ms)
Mic delay
- 0 ms → direct
- 1–5 ms → depth
- 5 ms → space effect
very useful for simulating double mic
Ambience (Y/N)
- OFF → close mic
- ON → improved simulated environment
Amb Level (dB)
Room volume.
- low → natural study
- high → ambient
Amb Size (ms)
Room size.
- 20–40 ms → small study
- 40–80 ms → medium study
- 80–120 ms → large
more credible than the other Flathills
Suggested Microphones
This cab is designed to accept all mics well
- SM57 → less harsh than other Flathills
- MD421 (variants) → very full and controlled
- SM7 (variants) → very smooth
- Rezio → modern, hi-fi
here: SM57 is also more “studio-ready”
here they really shine: very natural sound less need for EQ
IMPORTANT DIFFERENCE: On this cab they work MUCH better because the cab is less aggressive
