This one will be really short and sweet. But Al is known to mic the f-hole of the bass about 18 inches away with either a Neumann U47 or Neumann M149, and he mics the fingerboard where the player is fretting at about 9-10 inches away with either of the same two microphones.
He sets the mics to cardoid to combat leakage from the drums.
And then sends that signal to the Summit Audio TLA-100 compressor for a dB or less of compression. He uses the compressor for color not actual compression.
