Michael ACM800 212 Combo (R)

Inspired by Marshall® JCM800 2x12 (Combo, Right Speaker)
2x12" Speaker

same cab as (L):

  • 2x12 Marshall-style
  • open/semi-open
  • JCM800 voicing
  • BUT (R) = Right speaker / different microphone position, slightly different answer on, high, medium, focus, SOUND CHARACTER, Compared to (L), slightly more brilliant, more defined on the highs, less “full-bodied” in the low-mids, more focus on detail, in practice more suitable for, defined rhythms, mix, stereo pairing

Controls

Gain (dB)

Mic volume

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

VERY IMPORTANT

  • 0–1” → very bright
  • 1–3” → balance
  • >3” → more natural
  • compared to (L) -> here it is better to stay slightly further away
Mic Axis (On/Off)
  • Hon → very bright
  • OFF → warmer
  • here -> OFF often mandatory ON only if attack is needed
Low (dB)
  • negative → tighter
  • positive → more body
  • here -> you can boost slightly to compensate
High (dB)
  • negative → less harsh
  • positive → more presence
  • often -> need -1 / -3 dB
Delay (ms)

Signal delay.

  • 0 ms → direct
  • 1–5 ms → depth
  • 5 ms → space
  • useful for -> simulating dual stereo mics
Ambience (Y/N)
  • OFF → close mic
  • ON → simulated environment
Amb Level (dB)
  • low → natural
  • high → ambient
Amb Size (ms)
  • 20–40 → small room
  • 40–80 → study
  • 80–120 → large

here: it helps a lot to make it less “sharp”

Suggested Microphones

this cab is:

  • mid-forward
  • but more open on the highs than (L)
  • SM57 → perfect for rhythms
  • MD421 (LC1) → adds body
  • SM7 → lead smooth
  • Rezio → modernize

BEST MATCH:

here they reduce brilliance and make the sound bigger

Often best choice for study

very detailed here with high risk too evident

Usage: OFF-axis longer distance
