If you build a modular rig, this module gives you two ring modulators in one 4TE panel. It multiplies two signals together and handles both positive and negative voltages, which is what sets it apart from a VCA. It suits you if you want bell-like sounds or speech alienation, and you will need a supply that provides 12V and -12V.
Pros
- Contains two separate ring modulators in one module
- Multiplies two inputs, X * Y, to produce the output
- Handles both positive and negative input voltages (4-quadrant multiplication)
Cons
- Needs 12V and -12V power, drawing 40mA and -30mA
- Takes 4TE of rack width and 40 mm of depth

7 for sale on Reverb1 finish at Thomann
You might like this module if you build a modular rig and want to blend two signals together. It also works as an insert, so you can run an external effect through it. Its small size and low power draw make it an easy fit for a Euro rack.
Pros
- Works as a crossfader that blends between two signals in one module
- Can also sit inside a signal path as an insert for external effects
- Compact 8 HP width fits easily into a Euro rack format
Cons
- Only 8 HP wide and 40 mm deep, so it needs rack space to fit

Behringer 1005 ModAmp Ring Modulator / VCA Eurorack Module
Modamp Module 1005 · Behringer
2 for sale on Reverb1 finish at Thomann
If you build Eurorack setups, this module gives you two jobs in one 16 HP panel: ring modulation and voltage-controlled amplification. You get two signal inputs, two adjustable CV outputs for steering external oscillators, and gate inputs to switch modes. It suits you if you want a compact way to modulate and shape signals in your rack.
Pros
- Ring modulator and VCA combined in one 16 HP Eurorack module.
- Two signal inputs, each with its own level control.
- Switch between MOD and UNMOD mode to use it as a ring modulator or a VCA.
Cons
- Draws 60 mA (+12 V) and 45 mA (-12 V), so your Eurorack power supply must provide both rails.
-
You get a small module that fades between signals, and it works with both audio and control voltage. It suits you if you build a modular rig and want a compact way to crossfade sounds. It takes up little space and draws little power, so it works well for builders with a tight case.
Pros
- Crossfades audio signals as well as CV signals under voltage control
- Dual VC design gives two voltage-controlled crossfade channels in one module
- Compact 4 HP width fits into a modular case with limited space
Cons
- Only 4 HP wide and 45 mm deep, so your case needs room to fit it
-
This is a small Eurorack module that does two jobs. It turns triangle waves into sine waves, and it can blend two signals using a control voltage. It suits you if you build a modular setup and want a module that takes up little space.
Pros
- Combines two functions in one compact module: sine converter and VC crossfader.
- Converts triangle waves to sine waves.
- Voltage-controlled crossfader lets you blend two signals with a control voltage.
-
You get four useful tools in one small Eurorack module. It covers ring modulation, noise, sample and hold, and an LFO, so you can build patches that change and move on their own. It suits you if you already run a Eurorack setup and want more modulation sources without using up much case space.
Pros
- Analogue ring modulator for metallic, bell-like sounds
- White noise and pink noise on two separate outputs
- Sample and hold unit with clock out, external clock in, and clock rate and lag time fader
Cons
- Needs a free 16 HP slot in your Eurorack case, so plan your space first
How to choose the best ring modulator, crossfade modules
Sound Quality
This is the big one. We're looking for that characteristic ring modulation grit - a metallic, clangorous tone - or a smooth, musical crossfade without excessive noise or distortion. Cheap modules often have a harsh, brittle quality; we're prioritizing those with a more usable sonic palette.
Noise Floor
Ring modulators, especially, can be noisy beasts. A low noise floor is crucial, especially if you're recording. We're listening for hiss, hum, and unwanted artifacts that can muddy your mix.
Modulation Options
Does it just ring modulate or crossfade? Can you control the rate or depth? More flexibility means more creative possibilities, even on a budget.
Build Quality
Let's be real, under $100 means compromises. We're assessing the robustness of the pots, jacks, and overall construction - how likely it is to survive gigging or frequent patching.
Ease of Use
A complex interface can be frustrating, especially when you're just trying to dial in a cool sound. We're favoring modules that are intuitive and easy to integrate into your existing setup.
Buying guide
Alright, so you're chasing that alien wobble and swirling textures, but your bank account isn't cooperating? Ring modulators and crossfade modules can be absolute game-changers, adding movement and unexpected timbres to everything from pads to leads. We're diving into the best options you can snag for under $100 - because sonic weirdness shouldn't require a second mortgage.
At this price point, expect some trade-offs. You're unlikely to get pristine audio or premium components. Many will have plastic enclosures or slightly scratchy pots.
The biggest compromise will be in modulation options - don't expect LFOs or complex routing. Focus on finding a module with a usable sound, even if it's not the absolute cleanest. A little noise can be part of the character, but it shouldn't be overwhelming.

Questions
Will a $50 ring modulator sound as good as a Eurorack module costing $200?
No, definitely not. The more expensive modules will offer superior sound quality, lower noise, and more advanced features. But a decent $50 module can still get you interesting results - it just requires more careful tweaking and potentially some extra filtering.
What's the difference between a ring modulator and a crossfade module?
A ring modulator creates a complex, metallic sound by multiplying two signals. A crossfade blends two signals together, allowing you to morph between them. They're used for very different effects, but both can add movement and texture.
Can I use these modules with a guitar?
Absolutely! Ring modulation with guitar can produce some seriously gnarly, sci-fi tones. Crossfading is great for subtly blending different guitar sounds or creating rhythmic effects. Just be mindful of headroom - guitar signals can be hot.
What's 'noise' in the context of a ring modulator?
It's unwanted hiss, hum, or static that's introduced by the circuit. Some noise is inherent in ring modulation, but excessive noise can mask the desired tones and make it unusable. Listen closely before you buy.
Are there any known reliability issues with these budget modules?
Plastic enclosures are prone to cracking, and the potentiometers (pots) can get scratchy over time. Treat them with care, and consider replacing the pots if they become a problem - it's a fairly straightforward repair.
