Ample Bass P 4.0 for Mac is Ample Sound's take on the classic Fender Precision Bass, the split-coil workhorse that has anchored rock, soul, Motown and pop records for decades. Version 4.0 moves the instrument onto Ample Sound's newest engine, pairing the familiar warm, punchy P-Bass character with a modern MIDI composition workflow for producers who write basslines rather than play them.

Two libraries, Fingerstyle and Pick, cover both rounded finger playing and firmer picked parts, and the samples are recorded at every fret without destructive processing so the tone stays natural in a mix. This is paid software from Ample Sound, not a free full version; a trial is available from the official product page, which is also where you will find the current price.

Key Features

• Fender Precision Bass samples in Fingerstyle and Pick styles, 5.2 GB of content in the current build
• 13 articulations: sustain, palm mute, harmonic, hammer-on and pull-off, slides, slap, pop, tap and more
• Riffer 4 MIDI editor with piano-roll and tab views, string visualisation and a large riff library
• Built-in amp system with three bass amp heads, four cabinets and four microphone models, plus EQ, compression, delay and reverb
• AU, VST2, VST3 and AAX plugins plus standalone, for macOS 10.15 or later on Intel and Apple Silicon

Does Ample Bass P work in Logic Pro?
