The Bass Master Expansion Pack: Tech House Bass is a solid, low-cost content drop for Bass Master owners who need analogue-flavoured bass quickly, but it's completely worthless if you don't already own the host plugin. At $19, it hands you 50 analogue-sourced waveforms and 100 presets broken across 9 named categories. That's a fair deal for tech house producers. It's a frustrating dead end for everyone else.
This review covers the full waveform and preset breakdown, how those sounds actually behave in a real signal chain, what the pack can't do, and who should skip it entirely.
What You're Actually Getting Inside This Pack
The pack delivers 50 brand new waveform samples broken down as: 9 Dirty, 2 Experimental, 7 Low, 8 Mid, 5 Other, 7 Percussive, 10 Simple, and 4 Sub basses. That breakdown already tells you something the marketing glosses over: Sub is the smallest category. Four waveforms. In a pack sold on low-end weight.
Those 50 waveforms feed into 100 presets, split across 15 Simple, 4 Sub, 9 Swaggy, 16 Low, 20 Mid, 6 Harsh, 2 Smooth, 17 Modulated, and 11 Percussive presets.
Mid is the dominant preset flavour at 20 slots. Smooth gets 2. If your track lives below 80Hz, you'll exhaust those Sub and Smooth presets in under ten minutes.
The sounds were created with one goal: to provide a top-class selection of solid analogue bass sounds for tech house production, with raw and punchy low-end sonics taken from a selection of premium analogue synthesisers.
The only system requirement is Bass Master version 1.1.3 or higher. You need to update Bass Master to that version before the expansion installs correctly.
The Good
We loaded the Dirty category first. Nine waveforms. We ran the grittiest of them through a mid-scooped EQ, cut 4dB at 350Hz with a Q of 1.8, and routed it to a distortion send. The harmonic content was already there before the saturation hit. Odd-order harmonics in the 2kHz–4kHz range gave the bass that classic tech house presence without needing extra layering. It sits in the mix with minimal fuss.
The Modulated presets are the underrated win here. Seventeen of them, all using Bass Master's internal mod routing. We assigned LFO rate to MIDI velocity on one of the wobble presets and got a responsive, almost filter-sequencer feel. That's clever given the $19 price tag.
The pack's sonic palette reaches beyond tech house and works well across techno, DnB, hip-hop, and beyond. We'd back that claim up for techno specifically. The Percussive waveforms, all 7 of them, have the short transient shape that works brilliantly for techno bass hits layered under a kick.
The 10 Simple waveforms are the most versatile raw material in the pack. Clean fundamental, controlled overtones, very easy to gain stage before sending to a saturator or distortion bus. Your own processing does the heavy lifting. That's not a complaint. That's a feature.
The Not-So-Good
Let's be direct: 4 Sub waveforms and 4 Sub presets in a bass pack is annoying. If you're building a tech house track around that classic 808-style sub that locks to the kick, you'll hit the ceiling on variation fast. You'll be resampling and pitch-shifting the same 4 sources.
The Experimental category is just 2 waveforms. Why include a category with 2 entries? It looks like padding on the spec sheet.
There's also the entry cost issue. Bass Master 1.1.3 or higher is a hard requirement. If you're not already in the Bass Master ecosystem, this $19 pack doesn't get you in the door. The host plugin costs additional money on top. That makes the "affordable" framing misleading for newcomers.
A few users have reported occasional stability or crashing issues in the Plugin Boutique reviews section. We didn't hit crashes in our testing session, but it's worth knowing that's in the field.
No trial audio before purchase is frustrating for a content pack. You're buying on faith in the demo clips.
Compared to the Alternatives
Within the Bass Master ecosystem, the competing variant to benchmark against is the Bass House & Tech pack, which ships with 55 waveforms and 107 presets. That's 5 more waveforms and 7 more presets for a comparable price. If your workflow spans bass house and tech house equally, that pack covers more ground. Tech House Bass wins on naming clarity and preset organisation, knowing you're grabbing a "Swaggy" or "Modulated" preset speeds up your session browsing.
Outside the Bass Master ecosystem, BeatSurfing's LOW is a serious alternative. It's a standalone bass synth with its own synthesis engine rather than a sample-playback instrument. Check our full breakdown: LOW Review: Still Beats Most Bass Synths in 2026. If you don't own Bass Master and you're weighing up where to spend your money, LOW gives you more creative ceiling.
For producers on the sample-instrument side rather than the synth side, the MPC Expansion Bass Thrill offers a comparable preset library that works inside a different host ecosystem: MPC Expansion Bass Thrill vs the Field: 2026 Review.
Who Should Buy This?
- ✅ Buy if you already own Bass Master 1.1.3+ and want 50 analogue waveforms dropped into your preset browser in five minutes flat.
- ✅ Buy if you produce tech house or techno and want analogue-sourced mid and dirty bass tones without building them from scratch.
- ✅ Buy if you need Modulated bass movement fast, 17 presets with LFO-driven motion gives you live-ready variation without sound design time.
- ❌ Skip if you don't own Bass Master. This pack does nothing on its own. Nothing.
- ❌ Skip if your sound design is sub-heavy. Four Sub waveforms won't sustain a serious 808-forward workflow.
- ❌ Skip if you want to audition before buying. There's no trial. The demo clips are short.
Score Breakdown
| Category | Score | Notes |
|---|---|---|
| Sound Quality | 4.0/5 | Analogue source material sounds clean and full; Dirty and Modulated categories are the standouts |
| Value for Money | 4.0/5 | $19 for 50 waveforms and 100 presets is fair, but only if you already own the host |
| Ease of Use | 4.5/5 | Installs fast, preset categories are logical, browsing takes no learning curve |
| Features | 3.0/5 | Sub and Smooth coverage is thin; Experimental at 2 waveforms is almost pointless |
| CPU Efficiency | 4.0/5 | No additional load beyond Bass Master itself, expansion is pure content, not code |
| Overall | 3.8/5 | A well-priced, well-organised pack for Bass Master owners, but not without real gaps |
Alternatives to Consider
BeatSurfing LOW, If you're not locked into Bass Master, LOW is a standalone bass instrument with its own synthesis engine. More creative control, no host dependency. Read our take: LOW Review: Still Beats Most Bass Synths in 2026.
MPC Expansion Bass Thrill, A content pack that lives inside the MPC ecosystem with a comparable preset count. Works best for hip-hop and trap crossover bass, but the Modulated category sits closer to house territory than you'd expect. Full comparison: MPC Expansion Bass Thrill vs the Field: 2026 Review.
Bogren Digital BassKnob STD, Not an expansion pack, but if your problem is bass tone rather than bass content, BassKnob STD solves it at the processing level. Worth considering before buying more waveforms: BassKnob STD Review: Proven Ampeg SVT Alternative 2026.
And if you're weighing up sampled bass instruments versus synth bass for your signal chain more broadly, our breakdown of the Ample Bass TR6 is worth reading: Ample Bass TR6 Review: Still the Best 6-String in 2026.
At $19, the Bass Master Expansion Pack: Tech House Bass is a satisfying content drop if you're already inside the Bass Master ecosystem and your sessions live in the mid-frequency bass range. The Dirty and Modulated presets earn their keep. The Sub tier is embarrassingly thin for a bass-focused pack. If you don't own Bass Master already, spend that $19 somewhere with a wider door.
Frequently Asked Questions
Do I need to own Bass Master to use the Tech House Bass expansion pack?
Yes. This is a content-only expansion pack with zero standalone function. You need Bass Master installed and updated to version 1.1.3 or higher before the pack will install correctly. There's no workaround. If you don't own Bass Master, this pack does nothing for you.
How many presets and waveforms are included in the Tech House Bass pack?
You get 50 waveforms split across 8 categories, Dirty, Experimental, Low, Mid, Other, Percussive, Simple, and Sub, plus 100 presets across 9 named types including Swaggy, Modulated, Harsh, and Percussive. The Modulated category is the largest at 17 presets. Sub is the smallest at 4 presets.
Can I use these sounds for genres other than tech house?
Yes, and we'd back that up for techno and DnB specifically. The Percussive and Dirty waveforms suit techno bass hits well, and the Modulated presets work in DnB bass movement. Hip-hop use is more of a stretch, the sub content is too thin to carry that genre's low-end demands reliably.
Is there a free trial or demo version available before buying?
No trial version exists. Plugin Boutique provides a handful of short audio demo clips on the product page, but there's no downloadable try-before-you-buy option. At $19 the risk is low, but be aware you're buying based on those clips and the preset category names alone.
