8 Best Upright Bass VST Plugins 2024

Best Upright Bass VST Plugins

An upright bass (or double bass) is a favorite in traditional, classical, jazz, and sometimes even modern genres.

The upright bass is the largest, and lowest pitched of all stringed instruments in an orchestral situation, and just as its name would imply, it’s perfect for holding down the deep low end in a mix.

Its sound can be powerful no matter the context. In this guide, we look at the best upright bass VST plugins.

MELLOW 2 by ujam – Best Overall

MELLOW 2 by ujam – Best Overall

ujam’s Mellow 2 is ideally suited as a jazzy upright bass instrument for jazz, singer-songwriter, hip-hop, and R&B (not so much for traditional musical genres). That said, what it does, it does very well.

The user interface is very nicely designed and simple. Your main parameters are position (neck, bridge), character (soft, deep, natural, hard, tight), mic (hollow, full, round, present), room (from 0 to 100), drop D, octaver, finisher, equalizer, and compressor.

Mellow 2 features 60 styles with 1,380 phrases. Version two comes with 20 new styles, 30 new presets, 15 Finisher effects, MIDI drag and drop, and conveniently, backwards compatibility.

For your orchestral and scoring needs, you’ll probably want to look elsewhere. But for most other genres, Mellow 2 is more widely applicable. That makes it is our best overall pick.

Mellow 2 is a standalone module and doesn’t require Kontakt to work.

What Should I Look For In An Upright Bass VST Plugin?

Upright bass VST plugins are in relative scarce supply. There aren’t too many options to choose from, though the ones available are good.

This guide, in case there was any doubt, only features three dedicated upright bass VST plugins. All the others are string libraries or compositional tools. That said, it is possible to isolate the double bass section with some of them.

So, there are a few basic things to think about when it comes to shopping for upright bass VST plugins. Let’s look at – sound quality, features, and budget.

Sound Quality

If you’re going to spend a pretty penny on an upright bass VST plugin, it stands to reason you’re probably after an organic, realistic sound.

In this case, you can rest easy knowing that our top three picks – MELLOW 2, Nordisk Kontrabass, and English Bass, all have a great sound. If in doubt, though, go and check the audio samples as well as video demos and reviews for yourself.

But one thing to think about here is whether you need the traditional, bowed articulations (Nordisk Konbrabass), plucked jazz articulations (MELLOW 2), or more sound design, textural oriented sounds (English Bass). This will be a major determining factor here.


The way it works here is that the more you pay, the more features you get. Simple, right?

But more features aren’t always better, and it honestly depends on what you need for your projects.

If you’re comparison shopping, this is a key consideration, but otherwise, you may still want to prioritize sound and cost over fancy parameters. At the end of the day, it depends on what you need.


An upright bass VST plugin or strings VST plugin is going to run you anywhere from about $95 to $550. Our only note of caution here is to spend responsibly. Avoid going into debt for VST plugins, as there are always free alternatives you can use while you save up for better, premium options.
