When to Give Up

ev re18If you’ve followed my microphone reviews and opinions, you might know that I am a big fan of Electrovoice’s RE-18 Variable-D hand-held vocal mic. I bought my first RE18 in the 70’s, new, and I’ve owned a dozen or so since. In experiments with a variety of vocalists, I’ve found this microphone to be superior to almost every other live vocal I’ve ever used. In every area (except one), the RE18 excels: handling noise, off-axis rejection and frequency response, proximity effect control (Variable-D), max SPL, distortion, clarity, humbucking noise-rejection, and durability. The one negative, repairability, is the focus of this article.

At one time, Electrovoice offered a “lifetime warranty” on all RE series microphones. After a few years of downsizing, being aquired by a variety of conglomerates, and lowered expectations, that “lifetime” is currently being defined as a "limited lifetime warranty on the acoustic element (due to defect in materials or workmanship), defined as ten years from the last date of the products manufacture." EV seems to have “lost” all of the technical information regarding many of the company’s most respected products, including the RE18, but I suspect that mic went out of production in the late 80’s when EV had all but disappeared from professional audio. Even getting an EV tech support person to admit that the RE18 ever existed requires arm-twisting.

One of the best features of the RE18 was it’s amazing lack of handling noise. That capability as created by incorporating shock-isolation between the element and steel outer case that used butyl-rubber doughnuts and viscous damping fluid. The foam breath and pop filtering was pretty sophisticated, too. To this date, I have not been able to find anything resembling a description of the parts required to repair this shock isolation system and it’s clear that 30+ years of use or improper storage will turn all of those parts into an unrecognizable mess of disolving chemicals. The shock isolation system for my RE18 remains incapacited.

RE-18 2With the assistance of the one helpful tech service person at EV, I was able to obtain a replacement foam filter and Variable-D baffle for their current version of the RE16, but that is a long way from anything used in the original RE18 design. The RE18 used a 3-layer pop filter system, but the RE16 is just typical low density foam. The once-impervious to vocal plosives and sibilance distortion RE18 is rendered passable with the RE16 replacement material.

After decades of recommending this microphone to vocalists of all sorts, I have to give in to the facts and admit that without some sort of support from the manufacturer or someone who was once involved in the design and/or production of this wonderful microphone repairing the RE18 is no longer practical. And, except in incredibly rare instances, I think you will find that upon removing the metal screen that every RE18 is likely in desperate need of serious repair. Typically, the foam has turned to a nasty combination of dust and sticky adhesive and the rubber shock mounts are likely totally deteriorated and there is no evidence that the viscous damping fluid ever existed or any way to determine what it once looked like for the purposes of fabricating a replacement system.

The RE18 shows up often on eBay and Reverb.com; often with an asking price of $200-or-more. Knowing that the microphone is likely in an unrepairable and deteriorating condition, it makes no sense to invest that kind of money in a once-terrific instrument. I would not, under any conditions, pay more than $100 for an excellent condition RE18 and sight-unseen (and before disassembly and inspection) no more than $20 for an on-line sale. At the absolute least, ask the seller to remove the metal screen and take a picture of the foam being distorted with a finger or blunt object to determine if that material is in a state of extreme decay. Usually, when the screen is unscrewed and removed the foam will fall out in pieces and clumps of dust.

Even the RE20 appears to be getting left behind in EVs drive to compete with Peavey or one of the other cheap companies. I have an RE18 and two RE16s and a half dozen RE15s and RE10s. I wouldn't trade them for all the 57s and 58s ever made.

Over the dozen years I taught audio engineering at Musictech College and McNally Smith College of Music, I accumulated a lot of material that might be useful to all sorts of budding audio techs and musicians. This site will include comments and questions about professional audio standards, practices, and equipment. I will add occasional product reviews with as many objective and irrational opinions as possible.
