What makes a good vocal harmonizer pedal?
When searching for the right vocal harmonizer pedal, there are lots of things you need to look at closely. And it’s not all about the effects that are on offer. There are things like their suitability with instruments, ease of use and how they add to your performance. So what are the key things you should look out for?
Before going into how any effect affects your vocals, think about how the device works with your performance style.
If you are just a vocalist without instrumentation, then having no input or output slots isn’t a deal breaker. Yet, if you perform with an instrument, then everything changes.
Not every vocal harmonizer pedal has good support for external devices. If you find an effects pedal limits the gear you can use, then it may not be the best device for your needs. Take a long, hard look at these aspects before going into any more detail.
Ease of use
With using a harmonizer pedal, it needs to be easy to use.
We aren’t just talking about placement either. It’s about looking to see if you can bring up different effects quickly, finding the levels quickly and bringing up your preferred settings. Some devices will allow you to access this stuff via just one touch of a button—the seamless switch you should look for.
If a pedal requires hitting multiple button combinations or tapping through different settings, then it could hinder the quick changes that make these devices ideal.
It’s the same when managing effect levels, too. Most pedals will utilise a button-dial set-up where you highlight the mode you want and adjust it with a dial.
This is the best set-up to have, as you can see clearly what modes you are on. There’s some deviation on some models that have dials for individual features (effects, reverb, delay, etc.) which are just as useful and easy to use. However, try to avoid anything that doesn’t allow for easy ways to control effect levels when performing.
Types of effects
You will find that the effects themselves differ from model to model, and this is where the choice matters. The choice of effects is what can define how you sound—both on stage and in the studio. Some of the major effects to look out for include:
- Gender Shifting
- Multiple Harmonies
What these do is give you a true sound and ability to stand out from the crowd—each in their own way:
- Tracking: Tracking allows you to add pre-recorded loops over what you play in real time. These can last for several seconds or over a minute to give your sound real depth. It’s a great way to feel like others are playing with you.
- Gender Shifting: As the name suggests, gender-shifting effects shift your natural sounds either up or down octaves. By adding synthetic sounds of the opposite sex, it beefs up the vocal line.
- Multiple Harmonies: Essentially the same as multi-tracking in recording, adding extra harmonies can make it sound like 4 people singing at once. Having the ability to play three or four-part harmonies all from one device makes a difference—to both you and the audience.
- Vocoders: The favourite of singers and rock stars in the 1980s. The use of vocoders gives you that robotic tinge to your voice. It’s great for a shock to audiences and gives your sound a vibe that others may not think of adding nowadays.
By knowing how to control and master these effects it will allow you to select the best vocal harmonizer pedal for your needs.
Do all vocal harmonizer pedals have dozens of effects?
No, some vocal harmonizer pedals will only have a few to select from, whilst others will have dozens preloaded. It all depends on what you need for your sound to determine what is right for you.
Are all vocal harmonizer pedals wireless?
No—not all pedals are wireless. Many can run wirelessly or on batteries to a degree but may need charging. Some models will run solely on battery, though without a need for a wall connection.
Will all vocal harmonizer pedals support instruments?
No—some will have limited connections for instruments to connect to. Look to see what input and output slots a device has to determine whether it supports live instruments or just computer feeds.
What is the best vocal harmonizer pedal out there?
It’s fair to say that there is a good range of vocal harmonizer pedals out on the market today. Models such as the TC-Helicon Harmony Singer 2 may lack overall effects but make up for it with great usability. On the flip side, devices such as the FLAMMA FV04 and the Zoom V3 offer all the tech in the world to play with but can be tricky to master.
That is why we think the BOSS VE-2 is the best pedal out there today. Not only is it easy to use, but they load it with automatic features and effects that allow you to adjust as you perform, giving your vocal melodies the added kick without any unnecessary fiddling around. It’s these aspects that make it the best vocal harmonizer pedal on the market today.
