Superior Sound Reproduction

Legendary Producer/Engineer, and accomplished artist, Alan Parsons, granted an interview to Premier Guitar.  In the interview, he describes his mic’ing techniques for capturing such legendary guitar tones such as David Gilmore’s on “Dark Side of the Moon”.

Interestingly enough, we independently discovered this same technique and incorporate it into each of our cases which means you, too, can get legendary tone when you own one of our PICs!



Guitarists spend considerable time getting just the right sound.  Likewise, competent Sound Technicians spend hours upon untold hours learning and balancing a sound system in order produce the very best possible sound for a given situation.

There are a number of techniques when it comes to mic’ing a Combo Amp for recording or live sound.  The most popular is placing a single microphone in front of and pointing directly into the speaker cone of the Combo Amp, usually at very close proximity to the speaker.  It takes a lot of trial-and-error on the part of both the guitarist and sound tech to zero-in on the “sweet-spot” of the speaker, that one spot on the radius of the speaker cone that most closely reproduces the sound desired by the guitarist.  The true road-warrior guitarist will have this “sweet-spot” clearly marked on the grill covering the speaker, making set-up at the next gig faster (theoretically, of course).

A major innovation of the dB down PICTM is in the collection and transference of the sound from inside of the cabinet to the external mixing source.  Nestled securely inside the db down PICTM is our exclusive Focused Sound Technology (FST)TM, which eliminates the need for hours of microphone adjustments.  FSTTM captures all of the sound being put out by the amplifier and delivered through the native speaker, not just one small spot of the speaker!

We also strongly recommend the use of a superior microphone, the Heil Sound PR-31BW.  An American-made product, this directional microphone has a phenominal -40 dB rear and side rejection.  For the non-techie, this means virtually the only sound sent to the mixing console is what is in front of this magnificant microphone.  It boasts near flat frequency response across its wide 40 Hz-to-18 kHz range, and all this WOW is packed into a housing that is 4.25″ tall and 2″ in diameter.

For truly exceptional sound, a dB down PICTM with FSTTM paired with a Heil Sound PR-31BW is really the easiest decision a guitarist can make.

And for all you Sound Tech’s out there, getting your artists to try a dB down PICTM with FSTTM could honestly make you their favorite sound tech EVER.  Just don’t let on that it’ll make your job of mixing either FOH, monitor, or IEM mixes infinitely easier…

Individually Designed

Each dB down PICTM is custom designed and made to gently but securely house each individual Combo Amp for not only those environments that demand greatly reduced sound pressure levels, but for transportation as well.  Each dB down PICTM has an ATA Specification 300, Category 1 exterior armor that protects the contents from most of even the harshest transportation abuses.

The interior of each PICTM provides padding top, bottom, and both sides that “hug” the Combo Amp while a strength member spans the rear of the Combo Amp to secure it from unwanted movement in the instance of an accidental case drop.

Reduce Volume

The dB down PICTM uses layers of a dense material to greatly reduce the volume outside the closed cabinet.  Initial tests revealed a 20-25 dB drop on a cabinet with only a single layer of this material.

dB down PICsTM use a graduated layer approach to reduce sound transferance/transduction from the components inside the cabinet to the exterior of the cabinet.  This approach is integral to maximizing the “cushioning” effect on the perceived volume of the Combo Amp AND the actual cushion that envelops the Combo Amp, keeping it secure inside the PICTM.

Keep It Cool

Let’s face it, who wants to spend several hundred hard earned dollars on a Combo Amp, and invest countless hours dialing in the settings for the just the right sound, only to have a major melt-down and lose it all because the amp overheated after being put in a closed box?  That sounds like a recipe for a very short music career (or marriage should the decision be to replace the Combo Amp, especially if it is done on a regular basis)!

dB down PICsTM use active ventilation to draw cool air in and push the tube heated air out.  And because we isolate the front from the rear of the Combo Amp, the low-noise ventilation system is virtually imperceptible on the audio output of the cabinet!

About Us

At dB down, LLC, we custom design and build Isolation Cabinets (also called Iso Cabs) with a unique difference.

Guitarists purchase specific Combo Amps for a specific sound and then spend hours dialing in volume, tone, and gain settings to achieve a desired sound.  And since tube amps really don’t “warm up” with the volume turned way down, for the best sound they need to be turned up.

Herein is the dilemma for the guitarist; how to achieve the desired sound, and yet not cause permanent hearing impairment to the neighbors three houses down (not to mention those living in closer proximity)? The choices are:

  • Turn down the volume and gain controls to preserve hearing and domestic peace (sacrifice: “the sound”)
  • Hide the combo amp in some room far away from everyone to preserve “the sound” (sacrific: intellegability and need a much longer cord)
  • Get an Iso Cab

Most Isolation Cabinets on the market today share a single design ~ an external speaker encased in a sound deadening enclosure with single or dual microphones mounted inside to transfer the sound to an external mixing source.

This design is great IF the speaker in the Iso Cab matches the speaker in the Combo Amp, OR if the guitarist wants a different sound other than what is produced by the built-in speaker of the Combo Amp.

The problem, then, is most of the time, the speaker does not match and the guitarist must then change the settings on the amp to try and recreate the “sound” produced by the native speaker.  Then, of course, there is the fact that there is another “box” to cart around with all the other “boxes” of pedals, guitars, and cords.
