Suggested Microphones
Here the choice of mic is CRITICAL, more than on other cabs because:
on this cab: they smooth the highs and maintain the “chime” without harshness
BEST MATCH: R121= perfect AC30 sound
here: super details risk of high pushes
use: OFF-axis almost mandatory
here they can become too “nasal” or aggressive
They work for:
- crunch
- more hardcore rock
