For example, if threshold is set at -5 dB, then any signal above -5 dB will engage the compression effect. A good starting point is to set your compression ratio from around 2:1 to 4:1 which is a low to medium level. https://reverb.com/news/what-does-a-compressor-effect-do-the-basics The ratio parameter in this situation plays off the threshold setting. $18.99 $ 18. Hopefully, this information helps you too! Why Learn More Than One Pattern To Play A Bass Scale? which makes it really simple and easy to use; Again, no unnecessary controls to slow you down. People often prefer a soft knee with a lower threshold for a more fluid or less dramatic effect. However, at the most basic level, a compressor does exactly what its name implies: it compresses sound. Short and fast attack times can help tighten up and balance out loud, unintended spikes in dynamics inherent in fingerpicking and funky guitar styles. Contact Us Need Help? A compressor pedal evens out the levels of your playing by shaping the loudest parts of the audio signal. Save my name, email, and website in this browser for the next time I comment. The actual level at which the compressor steps in is set by the user with the threshold control (see below). But, even if you had no problem with input volumes, toggling a bass compressor pedal on and off to boost volume means you are already preset for solos or musical phrases where you want to jump out of the mix. Best Seller in Knee Braces. Although boss has kept its signature outer design, their bass compressor actually has a lot going on inside. (The two knob model contains more options inside the casing.) More info: ReaComp ↑ Back to top. All Rights Reserved. It comes with all the regular compression settings like; attack, release, ratio, knee, etc. Contact Us We're here to help. Although the design is based on FET, the M87 behaves like a VCA with a clean, hiss-free output thanks to their CHT (constant headroom technology) design. Once you start to get your head wrapped around the different variations and controls, you’ll start to see how much value compression adds to your tone. The third parameter of most compression effects is attack. Peak vs RMS sensing. A unique 3-in-1 effects pedal where you can choose between BUS (solid state compression), SYM (a darkglass designed compressor) and FET (based on the classic 1176) compression types. Keeley Compressor. If the ratio parameter is set to 2:1, that means for every 2 dB an audio signal is over the threshold parameter setting, the gain will be reduced by 1 dB, or by a factor of 2. This is akin to a faster attack. Ratio is the second parameter of most compression effects. The compressor doesn’t just clip the loud parts (that would be a limiter effect); instead it ‘shapes’ the loud parts, making them quieter while allowing some of the original nuances to remain. Maybe you have visited your local guitar store and noticed that some of the compression pedals available don’t have controls / parameters such as threshold, attack, release, ratio, etc. One other time-based parameter that is worth understanding is the difference between soft knee and hard knee compression. As far as simple interfaces go, the SpectraComp only has one knob to worry about. A higher ratio setting will substantially reduce the overall volume compared to a lower ratio setting. Threshold is measured in decibels (dB). Another boutique pedal. In other words, the gain will be reduced by a factor of 4. This also has the effect of making quieter parts of the sound (e.g. It seems simple enough, but the impact on how compression changes your overall sound quality is enormous. While you’re not at a disadvantage of changing a whole bunch of settings, it’s impossible to do so while standing in front of an audience. Ratio is set at 2:1, 4:1 and 10:1 through a toggle switch, and the gain meter can be switched between gain reduction, input or both signals simultaneously. If the gain of a signal is heavily reduced and then quickly released, there will be a pulsing effect caused by the sudden return of the signal’s gain. The key is to experiment with as many of them as you can to find the tone you are searching for. I started out by plugging in a Fender Ultra Jazz 4-string because I wanted to see if I could get a modern, active Jazz bass to sound a little less modern and controlled, both in the highs of the pops and the violent low-end attacks of an aggressively slapped 4th string. Some bass players prefer having more control over the finer aspects of compression, the M87 is designed with this in mind to include release, attack and compression ratios via control knobs. The threshold parameter controls the level at which the compression effect will engage. Release is the fourth control found on most compression effects. The mechanics of turning each knob automatically changes multiple compression settings hidden from view, but doesn’t distort or change the color of your tone. The configuration is more complex which means it will take longer to master the controls, but it does mean you have a lot more fine tuning options to play with. The initial compression part of the effect affects just the loudest parts of an audio signal. A lower threshold setting means that a larger piece of an audio signal will be compressed. If the ratio parameter is set to 4:1, that means for every 4 dB an audio signal is above the threshold setting, the gain will be reduced by 1 dB. However, too much attack will leave your tone bland and lifeless. Attack parameter times generally vary from 1-100 ms. For example, a short attack setting of 1-10 ms means that the gain reduction ratio of the compression effect will take place 1-10 ms after the audio signal has breached the threshold. There is a “bend” in the line making the compression gradual until it reaches the maximum ratio dialed in. Keeley Compressor Pro Professional Studio Compressor Pedal Studio/Stage Compressor/Limiter with Hard- and Soft-knee Compression, Exact RMS Analysis, LED Display, Auto Mode, and True Bypass $254.15. This results in a flatter, more even tone. Guitar Buying Advice For Beginners. All four of these parameters influence one another in different ways. The two attack settings are LED which provides a fast attack speed, and Lamp which is slower to allow more initial pick, slapping or pops to filter through before compression takes place. Bass compressors solve this problem by ‘squashing’ or compressing soft and loud signals to the same volume level. Contact your Sales Engineer. Amazon's Choice for soft knee brace. 4.3 out of 5 stars 14,525. Exactly how the loud parts are shaped depends on both the compressor pedal being used and the settings being used. Now that you have some understanding of the basic parameters of compression effects, you may be wondering when to use compression on guitar…. Seymour Duncan’s design is similar to the Keeley Bassist compressor in simplicity but with a few changes to the interface controls. Attack is measured in millisecond (ms). The minimal design is backed by a much more complex back end, there are a lot more controls to take charge of through their software based TonePrint app. Longer release times produce a more even-feeling dynamic, but like a fast attack time, can leave the guitar tone a little dehydrated. Another high grade VCA bass compressor with studio internals which produce a clean and powerful punch. Sensitivity can mean threshold – perhaps pedal manufacturers think that guitarists aren’t interested in the ‘boring’ concept of threshold and instead are more likely to purchase a pedal if it will increase the perceived ‘sensitivity’ of their guitar? You may have played with a compression pedal at your local guitar store and felt overwhelmed by the wide array of parameter controls. This is akin to a slower setting on the attack parameter, but unlike the attack parameter, soft knee describes more the style of compression and is not generally a parameter that can be manipulated in the same way as attack, release and ratio.
