Over the last few decades, we are seeing more and more guitar amp manufacturers making Isolation Cabinets or “Iso Cabs” as they are usually called by working musicians. The reason for this is simple. Sound engineers and stage technicians are continuously telling guitarists to show down in order that they can control the sound from the Front of House (FOH). Everybody knows the general FOH sound is at all times finest when the FOH sound engineer has total control over the musical devices level in the venue. Sounds easy proper? Well this is the problem. The dilemma is the fact that guitar amps often have a sweet spot where they sound the best. Unfortunately, this sweet spot is often obtained by turning the guitar amp up to a higher level. More technically, the guitar amp needs to be turned up to a degree that the preamp tubes and energy tubes are being pushed a bit. This added volume allows the amp to “open up” so to speak. To not sound choked or filtered by electronics that attenuate and diminish the pure tone of the amp. There are quite a few electronic variables to consider that affect the overall tone and really feel of the amp so please take my word for it on this one, guitarist need to crank there amp for good reason.
Guitarists and producers all love the recorded sound of a cranked Marshall or Mesa Boogie guitar amp pushed to the limit. However, most leisure venues, houses of worship, theaters, Broadmethod shows, clubs, casinos, and so forth, don’t want the overwhelming stage quantity that comes from cranking a 50-100 watt guitar amp. Some guitarists have chosen to go the amp modeling/digital effects processor route which has come a long way. This option can sound quite good when you have an ear and take the time to learn to program the unit. As a matter of reality some musicians even swear by it. With that said, the actual fact stays that the overwhelming majority of working guitarists want to use the amp and setup that they’re comfortable with and have used for years to create “their tone”. That brings us back to the isolation cabinet.
Isolation cabinets permit the guitarist to make use of the precise setup that they’re used to. This means the entire effects pedals and the amp of their selecting, and anything else of their stage signal chain. The isolation cabinet merely replaces the speaker or speaker cabinet within the guitarist’s setup. The complete isolation cabinet has a guitar speaker and microphone mounted inside it is enclosure. The cabinet is usually highly dampened with acoustic foam to attenuate inside reflections and to dampen the overall sound radiating from the unit. Relying on the quantity of the amp, some isolation cabinets can nonetheless be fairly loud and radiate a lot of sound externally. Another main concern with most isolation cabinets is the fact that they’re normally large and heavy. These cabinets often weigh between 60 and 80 pounds or more when loaded. Nonetheless, silent recording JLH Applied sciences manufacturers a small, table top isolation cabinet called the AxeTrak Pro. This unit weighs about 20 kilos, has an especially small footprint, and is the most quiet of all isolation cabinets being sold at this time.
There are a lot of options on the market so make sure you do your homework and check them out. An isolation cabinet could possibly be the solution you had been looking for!
