🏆 Trillian Bass - The Best Bass Guitar VST Overall 🏆


It’s hard to define the ‘best’ bass VST out there, since each artist has their own unique tastes, and different styles of music production have thier own requirements. I'm a Fender guy, but other (fools) might swear by a Rickenbacker or an Ibanez.

Thankfully, with the power of plugins and a decent midi controller, you can to tap into a world of sound from your home studio.


  Check out all the features of Spectrasonics Trilian Bass


So first plugin on the market I'd recommend - and the only one you may ever need is Trilian Bass Virtual from Spectrasonics. This is arguably the best bass guitar VST, and is the heavily sought after successor of the award-winning Trilofy software, and includes enhanced versions of the original patches in addition to a slew of new and customizable electric, acoustic and synth basses.

It's the only bass plugin you'll ever need, with meticulous samples of everything from electric bass (including all the major models of real bass guitars, like the Fender precision bass & fretless bass) to acoustic basses to more avant garde sounds like the Chapman stick. It even includes some classic synth bass sounds!



This Trilian Bass VST also includes a ‘Round Robin’ feature which gives repeated notes (a staple of groovy basslines) a human feel instead of a mechanical one at the flick of a switch. One of the big reasons Trillian has become an industry standard is its control allowing you to create realistic bass parts by easily triggering different techniques, like slides. With a little work, it can sound indistinguishable from the real thing.

You’ll be able to find any sound you need with ease by using the Spectrasonics browser that lets you filter sound by attributes, images and tags. On top of that, you've got the ability to use 33 built-in effects to perfectly sculpt your bass tones. All in all, the Trilian Bass VST is the best on the market for an all-around plugin. It also includes one of the best acoustic bass VSTs out there.


Pros of Trilian Bass Plugin:

Best Physically Modeled Bass


MODO BASS 2 elevates the game from its groundbreaking predecessor, IK’s first-of-its-kind, physically modeled bass virtuoso in a digital format. For us producers, the quest for that perfect bass tone is never-ending. MODO BASS 2.0 is like having a bass legend on speed dial, delivering the nuanced sound and feel of a top-tier instrument, all wrapped up in the convenience of a plug-in.

MODO BASS stands alone as the pioneer technology that simulates the entire bass-playing process. Ditching the old-school sample-based approach, it employs modal synthesis to inject vitality into your bass lines. It meticulously simulates how each string interacts with the musician's touch, the fretboard, the body, and pickups, capturing the essence of a real bass performance. Then, leveraging IK’s analog modeling finesse, it layers on the authentic sounds of an electric bass amp and effects rig.



This ends up sounding more natural while also saving a ton of hard drive space. Plus, it introduces advanced controls and even more gateways into the MODO BASS universe.

With MODO BASS 2.0, your palette expands to 22 iconic models, including the original 14 plus eight novel additions to cater to any musical genre as well as tons of built in grooves.

This bass is sampled from a late 1970’s jazz bass and has three different pick-up positions to choose from. If you're look for that tight funk sound, this is the choice for you.

It is so realistic that you can slide between chords and feel the timbre changes when you move between high and low frets. This plugin is created by Thomas Hansen Skarbye whose brand has become synonymous with world-class sound quality and playability which is why he has been chosen to work with artists like Alicia Keys and Nile Rogers.

From a Frustrated Producer in a Ragtag Bedroom Studio to Major Placements on TV Earning $1,000s!


My name is Evan, and I've been making music since around 3rd grade. I'm from San Diego, California, but I've lived in Washington, DC for the last 20 years.

After 3 grueling years of grad school, though I had put aside serious attempts at making music. I found myself spending my days doing work that was dreadfully uncreative, with a ton of student student loan debt.
Which made me feel like my favorite parts of myself were withering.
But I didn't know what to do about it.
Being in my early 30s with tons of student loan debt, in a world where there is "no money in music," I felt like my youthful dreams of trying to "make it big" were dead. Like my music would remain unheard in my head and hard drive. 
Frustrated by my inability to get my music heard, I started researching solutions.
Instead, I wanted to find a way where I could focus on making the music and let someone else deal with promoting it. 
I realized the music licensing was the perfect opportunity for a solo artist like me to get my music heard, without having to do any promotion. I just need to focus on improving what I could control - my songwriting and my production skills.

While I still have a full-time day job, I have created systems that have allowed me to produce dozens of songs a year in my spare time.

My songs have been on Netflix, TV shows like the 90 Day Fiance, an award-winning indie film, and NPR’s “All Thing Considered.” They've also been streamed millions of times.

In addition to being a music producer, I am passionate about teaching people how they can make professional-sounding music and earn money licensing it, all in their spare time.

Thousands of musicians, like yourself, have trusted me to guide their musical journey. My YouTube videos have been watched nearly a million times. And my story has been in Forbes, Side Hustle Nation, and the Side Hustle School.
