The best bass amp and bass DI plugins

Short answer

For free, go to TONE3000 and load captures of real bass amps and DIs into the free NAM plugin; Ignite's SHB-1 is a solid free amp too. For a SansAmp sound, Nembrini or Kuassa Bass Driver. For Ampeg, the SVT-VR. For modern metal bass, Darkglass Ultimate or Parallax X. If you want one bass to sound like a whole band, that is La Bestia.

Bass tone is mostly three decisions: a clean DI or an amp, how much grit, and how much of the low end you protect from that grit. Every plugin here answers those differently. The free options are genuinely good now, so start there.

I make Siesta Audio plugins, and mine are on this list, marked as mine. Everything else is here because people actually recommend it. Prices are rough list prices and change often, so check before you buy.

Free: start with TONE3000

TONE3000 is the best free resource for bass tone. Search it for SVT, SansAmp, Darkglass or whatever rig you are after, download the capture, and load it in the free Neural Amp Modeler plugin. Ignite's SHB-1 is a good free amp if you would rather have knobs than captures.

A SansAmp-style DI

The Tech 21 SansAmp Bass Driver is on a huge number of records, and plugins built around it are the quickest way to a finished, slightly gritty bass. Nembrini Bass Driver and Kuassa Efektor Bass Driver both go after that sound.

Ampeg, Darkglass and metal bass

For classic rock and the 8x10 sound, the Ampeg SVT-VR. For modern, aggressive and metal bass, Darkglass Ultimate or Parallax X, which split the low band from the distorted mids and highs so the bottom stays solid.

One bass as a whole band

La Bestia is not a DI or an amp sim. It runs a bass rig and a fuzzed guitar rig at the same time, so a bass alone sounds like bass plus guitar: the Royal Blood and Death From Above 1979 sound. If that is what you are after, it does it in two knobs. More on fuzzing bass in the best bass fuzz plugins.

Quick answers

What is the best free bass amp plugin?

Captures from TONE3000 played through the free Neural Amp Modeler plugin are the best free bass tones available. Ignite Amps SHB-1 is a good free amp sim with traditional controls.

Is there a SansAmp plugin?

Several plugins are built around the SansAmp Bass Driver sound, including Nembrini Audio Bass Driver and Kuassa Efektor Bass Driver. TONE3000 also has free community captures of SansAmp-style pedals.

What is the best bass plugin for metal?

Darkglass Ultimate and Parallax X, both from Neural DSP, are built for aggressive modern bass with the low end kept separate from the distortion.

Do I need an amp sim for bass, or just a DI?

Plenty of records use a clean DI only. An amp sim or DI-style drive adds warmth and grit; try your DI clean first and add drive only if the bass disappears in the mix.
