Reverb – good or bad?
Reverb can make a dry toneless guitar sound like something an angel played in a huge cathedral. It’s the tool of every producer making the music sound alive on record. Yet, reverb can also kill your tone and make every effort of producing the greatest tone on earth seem like a complete waste. In this article I’ll try to share some views on a topic that often cause a lot of debate.
Technical stuff
Reverb, or reverberation, is essentially many echoes with different time and decay that feed back upon each other. This “chaos” creates ambience or reverb. In regards to a concert hall – the larger the venue, the more reverb.
There are mainly two different kinds of electronic reverb, – spring and digital. Spring is commonly used in amps. The spring has a transducer at one end that converts the signal to vibrations that reverberate in the springs and are converted back to electrical signal. If your amp has a spring feature, you can rock it back and forth and you’ll hear this “crash” inside (a cool effect in it self!).
Digital reverb is basically a simulation of the spring, creating a more accurate type of reverb. Still cheap reverb units fail to create the natural dynamics of either a pring or a hall, small room, cathedral or similar. The more expensive ones have software that carefully simulates typical rooms, – the space, the absorption etc.
Using reverb
Reverb is used on most recordings to make the sound more alive and dynamic. Reverb is also often used to “hide” stuff, like vocals out of pitch or a guitar that’s too earpinching. If you’ve watched the BBC Dark Side of the Moon documentary, you can see how they used reverb on David’s guitars. The effect is quite dramatic as if you hear the guitar on a staduim. Almost any recording (or album) would have sounded extremely dull if it wasn’t for reverb and Pink Floyd certainly used this effect to “colour” some of their most beautiful moments.
There are basically two ways to add reverb on a recorded track. The most common way is to use studio units and digitally add the reverb. This way you can achieve almost any desired effect. Another, perhaps more exciting way is to use the ambience in the room where you’re recording. When mixing a guitar, you can add a second (or multiple) microphone in a distance from the amp. This mic will record the natural reverb in the room and when you blend these tracks you can get some pretty cool sounds (this is how they recorded the intro on “Sorrow” from “A Momentary Lapse of Reason“).
When you’re in the audience at a concert, you will notice that the sound has a lot of reverb. This is the natural ambience at the venue. A small place, like a club, will make the band sound very tight and dry while on a stadium or at an indoor hall, you’ll hear that the band sounds huge. No matter how big the hall is it’s almost certain that the guitars and drums (at least) don’t have additional reverb in the mix. And that’s where the debate starts…
No reverb!
I often hear from guitarists that’s just started playing or from people who just play at home that they need to use reverb or else the sound is too dull. And I’m not trying to sound like a mister “know-it-all” here…. it took me years to understand why reverb can be bad for your tone and I’m still no purist. Butl, what I always try to stress is: as a rule, you shouldn’t use reverb unless you’re using it as a specific effect.
When you plug your guitar straight into your amp’s clean channel, you’ll hear the direct signal from your guitar. When playing live, this setup should always be your basis… your fundament (whether or not you use the clean or gain channel). You’ll hear every nuance of your amp, your guitar’s pickups and your picking style. Any effects you add will colour that basic tone and add character and dynamics to your sound. When you play live, no matter how big the stage or venue, your sound will echo throughout the hall and reverberate naturally. To get to the point, – when you add reverb (spring or pedal/multi effect) you’ll be adding reverb on top of reverb. What’s being naturally blended with the ambience in the hall is already drenched in reverb. This is overkill and in most cases, your loyal fans won’t hear the neuances in the fantastic tone you’ve spent hours creating.
