Tip: Combining multiple microphone types can produce an interesting sound.
Duplicate the guitar track, and insert Amp Designer on both tracks. Select different
microphones in each Amp Designer instance while retaining identical settings for all
other parameters, then set track signal levels.
Bass Amp Designer
Logic Pro Bass Amp Designer overview
Bass Amp Designer emulates the sound of three famous bass guitar amplifiers and the
speaker cabinets used with them. Each preconfigured model combines an amp and cabinet
that recreates a well-known bass guitar amplifier sound. The amp and cabinet can be
combined with integrated compression and EQ units to alter the tone. You can process
signals directly, reproducing the sound of your bass played through these amplification
systems. Virtual microphones are used to pick up the signal of the emulated amplifier
and cabinet. You can choose from, and position, three different microphone types.
When recording, many bass players use a direct connection to a mixing board or other
recording equipment, often using a passive (non powered) or active (powered) D.I. box
(Direct Injection box). The use of a pre-amp with passive or active EQ and a hardware
compressor instead of, or in addition to, a D.I. box is extremely popular too. Bass Amp
Designer emulates a professional-level American D.I. box.
Bass Amp Designer has a two channel design—one for the pre-amp and one for the D.I.
box. This lets you flexibly change the signal flow for the following playing and recording
configurations: pre-amp with passive or active EQ, compressor, a straight power amp,
just the sound of the cabinets and microphones, D.I. box alone, bass amp alone, or both
in parallel. See Logic Pro Bass Amp Designer signal flow and Logic Pro Bass Amp Designer
Pre-amp flow.
The Bass Amp Designer interface is divided into four main parameter sections.
• Model parameters: The Model pop-up menu at the lower left of the window is used to
choose a preconfigured model, consisting of an amplifier, a cabinet, and a microphone
type. The other pop-up menus enable you to independently choose the type of
amplifier, cabinet, and microphone. See Build a Logic Pro Bass Amp Designer combo.
