Doc's Best 212 (Room)
It's a modeled cab + integrated room environment, Therefore:
- you have microphone close (main)
- simulated environment (room mic)
- Different from a pure IR you control here mic, position, EQ and room in real time.
Controls
Mic volume
- ↑ = more signal / saturation
- ↓ = more headroom
- It is NOT the amp gain → it is the mic output
Microphone-speaker distance.
- 0–1” → super direct, aggressive
- 2–6” → natural
- 6” → more ambient
CRUCIAL parameter
Position with respect to the cone.
- ON (on-axis) → center cone → brilliant, attack
- OFF (off-axis) → inclined → darker, smooth
one of the most important tone controls
Low cut/emphasis.
- negative → less boom
- positive → more body
High cut/emphasis.
- negative → less harsh
- positive → more presence
it's a simple post-mic EQ
Mic signal delay.
It is used to simulate phase/distance, align with other cab/mic
- 0 ms → direct
- 5 ms → “room / comb filtering” effect
Toggle the room on/off.
- OFF → close mic pure
- ON → add room
Room volume.
- low → natural
- high → ambient / live feel
Room size (reflection time).
- low (10–30 ms) → small room
- medium (30–80 ms) → study
- high (80–150+ ms) → hall / large space
It's like a combined pre-delay + size
Suggested Microphones
This parameter selects the type of virtual microphone used on the cabinet. HeadRush distinguishes between:
Dynamic (Dyn) → punch, mids, rock
Condenser (Cond) → details, hi-fi
Ribbon (Ribbon) → soft, vintage
SM57 / SM58 / SM7 → standard studio/live
MD421 (variants LC1/LC2/LC3/LCS/M) → more body and bass
- Rezio → type Heil PR30 (modern, defined)
Use:
leads → SM7
414B (all variations)
variants:
C = cardioid
O = omni
Fig 8 = bidirectional
LC = low cut active
Use:
IR-like realism → 4047
Use:
jazz, blues
to soften distortions
The more you go towards capacitors → more hi-fi
The further you go towards ribbon → darker
Dynamic = mix-ready
