10 of the best Eurorack modules under £100
There’s no getting away from the fact that Eurorack can be an expensive hobby, but not every purchase has to be a big one. Aside from the obvious patch cables, blank panels, mults and attenuators, there are plenty of interesting modules that come in at well under £100, and while you might not find many flashy oscillators, filters or effects at this price point, there are lots of tools and utilities that can bring a new dimension to your rack. Here are a few of our picks that are low on price but high on impact.
1. ALM Busy Circuits PE-1 (£81)
One of the more under-the-radar products in ALM’s catalogue is this two-band parametric EQ and simple two-channel mixer. Inspired by the EQ circuits used in early cassette-based Portastudios, the PE-1 is great for warming up a digital source, tweaking a feedback loop or extending a mixer.

£81.00
PE-1 is a dual-band parametric EQ and simple two-channel mixer. Two control sections provide a sweepable cut or boost to a selectable upper and lower...… read more
2. Erica Synths Black XFade (£99)
From Erica’s premium 'Black' range and boasting a lovely big knob, this is a great solution for smooth manual or CV-controlled crossfading between two audio or CV signals. The inputs can boost as well as attenuate, letting you get really creative with your modulation or audio routing.

3. Doepfer A-130-8 Octal Linear VCA (£74)
To be honest, we could fill this list with Doepfer modules (that’s maybe a blog post for another day) but for sheer value the A-130-8 is hard to beat, even by their standards. ‘You can never have enough VCAs’ may be a cliche but it’s also true, so getting eight for under a tenner each - along with a trio of mixed outputs - is a real no-brainer.
Doepfer A-130-8 Octal Linear VCA Eurorack Module
£99.00
Module A-130-8 contains eight linear voltage controlled amplifiers (VCAs). Each VCA features a control voltage input (CV), a signal input (In) and a signal output...… read more
4. Apollo View IOU (£99)
Comprehensive CV and audio signal processing is key when building a system, and this 2HP marvel from Apollo View will easily earn its keep. A DC offset slider offering up to +5V or +10V can be switched before or after an attenuverter for precise signal scaling and inversion. Dual polarity outputs round things off.
Apollo View IOU Invert/Offset Eurorack Module
£99.00
IOU is a highly flexible DC-coupled signal processor, suitable for both CV and audio inputs. It features an attenuverter for precise signal scaling and inversion,...… read more
5. Transient Modules 4R (£88)
This is a super-simple but incredibly handy 2HP device with two normalled trigger inputs that each produce two unipolar or bipolar stepped random voltages. It’s great for bringing life to voices - just mult your envelope trigger to the 4R and feed its outputs to the parameters of your choice and get a different variation with every note.
Transient Modules 4R Eurorack Random Module
£88.00
The 4R is a quad random voltage generator in 2HP. It generates two different random stepped voltages per input, each time a rising edge is...… read more
6. AtoV Project Gaeto (£99)
Logic modules are a great way to spice up your trigger and gate patterns, and this unassuming device offers a range of functions based on its clock and data inputs. It can be a clock divider, legato generator, trigger to gate converter, rhythm quantiser, sub octave generator and more - it really rewards experimentation.
AtoV Project Gaeto Eurorack Clocked Logic Module (Black)
£99.00
The AtoVproject Gaeto is a new type of clocked logic module. Gaeto is a great module to play around with triggers, gates and legatoes turning...… read more
7. Shakmat Modular HiPass (£85)
A quad fixed frequency 3-pole high-pass filter that can make all the difference to your sound, especially if you play live. The first two channels roll off below 30Hz - great for processing your main stereo output and removing non-audible signals that limit your headroom. The other two channels are set at 100Hz, like a low-cut on a mixer.
Shakmat Modular HiPass Eurorack Quad High Pass Filter Module
£85.00
HiPass is a quad fixed frequency high pass filter. The two first sections are 3-pole filters (-18dB/oct) cutting at 30Hz. This removes low frequencies generated...… read more
8. Zlob Modular Diode Chaos (£74)
Looking to bring a touch of unpredictability to your modular system? Look no further than this 3HP chaotic voltage generator from the always intriguing Zlob. It produces three phases of interrelated morphing voltages including a chaotic trigger out, ranging from 20-30 seconds a cycle right up to audio rate.
Zlob Modular Diode Chaos Eurorack Random CV/Trigger Module
£74.00
Diode Chaos is a 3HP analogue chaotic low-frequency voltage generator Eurorack module. It is a unique module because it has never existed as an electronic...… read more
9. Happy Nerding LED Meter (£100)
If you’ve got a 4HP slot to spare and you’re looking for a way to brighten up your rack a bit, then a 30-segment LED meter might be the answer. Each segment roughly corresponds to 1dB of level and you get a buffered copy of the input for onward signal flow. Visualising signals is always useful and this also looks very cool.
Happy Nerding LED Meter Eurorack Module (Green)
£100.00
LED Meter is a handy utility module designed to show audio levels. Four color versions are available: all blue color all yellow color green color...… read more
10. Winterbloom Big Honking Button (£92)
And finally… a big button that honks! This brilliantly bonkers module, available in six colours, is a simple sample player with pitch CV and gate in and out. Out of the box it’ll make a big old honking sound, but you can store up to 8MB of your own samples on it. What’s not to like?
Winterbloom Big Honking Button Eurorack Sample Trigger Module (White/Pink)
