The New U (...67 copy, that is)

On review today is the Peluso P67, modeled after the famous vintage (discontinued, and thus wildly expensive) Neumann U-67. It's not uncommon for well-maintained 67's to sell for upwards of $10,000. Until John Peluso spent over 2 years on the p67 to get it just right, attaining its signature sound (think the Beatles' Revolver, Bob Dylan, Chris Cornell's Soundgarden tenure, Kurt Cobain on "Nevermind", among many, many, many others) - meant shelling out big bucks in an expensive studio or, if you were lucky enough to live in L.A., New York, or Nashville, renting one for nearly the price of a month's mortgage payment.

Fortunately for us, Peluso Microphone Labs put in the time with several great u-67 specimens and tweaked the p67design til it closely matched the original, creating a mic that holds its own in shootouts with the best of engineer-ears.

The original u67 finds its use primarily on vocals, acoustic guitar, and less often (though no less spectacularly) on electric guitar cabs. I can't really describe with words what it does to the sound, but as this is a blog, I'll try...and you can listen to clips below.

It seemed to be that vocally (clips 1 and 2), it captured about what I'd expected - a nice low end, detailed midrange, and a crispy but not overhyped high end. In terms of high end, I'd put it somewhere between a u47 and a c12 (or for existing Peluso fans, a 2247 and p12). The midrange is where I really sensed something unique. Interesting handling of the critical 400-600 range, and a very unique sounding upper midrange. While the response is spec'd as mostly "flat", we all know the human voice is anything but, and putting several vocalists in front yielded a consistently unique, interesting EQ curve.

The mic was dense in the midrange, with a particular emphasis in the 500 region (a region typically reserved for things that occupy the "front" of a mix), and around the forward sounding 2k region, which would ordinarily yield a very "forward" sounding vocal track, if not for the interesting phasing/compression characteristics. More on this later. There was a high frequency air present as well which began its rolloff somewhere around 8k. In many ways, this is a "midrangey" mic, not boasting the warm, resonating low end and bright, airy high end of the p12. The clips of the acoustic are a great indicator of the low and high end differences (clips 3 and 4).

Most fascinating was the mic's tendency to sound somewhat compressed already, even filtered in a way. Some reading and novice examination of the u67 schematic shows several negative feedback loops, which without getting overly technical, loops the signal back in to earlier parts of the circuit, resulting in phase cancellation at certain frequencies and gives things a very unique color and a somewhat "squished" sound. (The forward, fast, "spanky" sound of a Vox AC-30 is primarily due to its LACK of negative feedback loops. The bloom and compression heard in many Two-Rock amps, particularly the John Mayer signature head, are the result of carefully tuned negative feedback.) The tube only accentuates this tendency toward compression, resulting in a sound similar to fast attack, medium release settings on a compressor...a sound known to push things "back" in a mix. This all comes together to bring us a mic that sounds detailed and forward EQ-wise without being difficult to place into the mix. Given the desire for compressed vocal sounds, it's no wonder 67 microphones are all over modern rock records.

I was most pleasantly surprised when I decided, given its interesting midrange, to try it on electric guitar cabs. No matter what sound came out of the amp, the resulting signal (again through the neutral FMR RNP) had an unmistakable vintage, retro vibe to it, a certain throatiness (due to its handling of the 500hz range) that perfectly accentuated the sounds of a Gretsch ( see clips 5 and 6) or Telecaster.

Needless to say, next time I need to record an edgy or aggressive vocal track or am in need of a vintage "vibe" to my guitar tracks, I will be reaching for Peluso's p67. You can do so as well at Rock n Roll Rentals, for $45 (weekend rate, Tuesday to Monday) or $100 bucks for the month.

Peluso P28: Your Acoustic's New Best Friend

I recently had the opportunity to record a mid-tempo track for Austin songwriter Paul Whitney, consisting of acoustic guitar, mandolin, brushed snare, hand percussion, and vocals. The goal here was to sound natural and close, with an intimate sense of space and a degree of polish without harsh brightness. So I set out to find some gear.

I've always felt frustrated recording acoustic guitar - it has to have warmth and body and transient crispness - all without sounding boomy or thin. I think we're all familiar with "cardboard box with strings" recordings of acoustic instruments, or worse, the god-awful "ice-pick on strings" sound often achieved by incorrectly chasing "sheen" and "polish".

Worse still, these problems can't be corrected with compression without very obvious artifacts - fine in a layered rock mix, but murderous to the vibe of a quiet acoustic song. My quest then, was to find a flat, natural microphone, one that could pleasantly squish some transients, and provide a warm tone while keeping a "woofs" and "booms" at bay.

Enter the Peluso P28 pencil tube microphone.

The Mic:
A small diaphragm condenser modeled after the classic AKG C28 (but at a fraction of the cost!) this condenser imparts the warmth and body so sought after with large diaphragm condensers (which would ordinarily "boom" and "scrape" on an acoustic guitar recording), with the accuracy and transient response of a small diaphragm condenser. Though listed as a small diaphragm condenser, at 18mm, it's larger than expected compared to something like a Rode NT5 (13mm).
What attracted me to this microphone was the tube, however - not because tubes are "rad" or "vintage" (although, they totally are), but because tubes are known for their natural compression characteristics, which seemed promising for handling pick noise and harshness.

The Setup:
Peluso p28, Rode Nt5, SM-57 Kel Audio HM7U
FMR RNP
Tascam USB 1641

I setup with a commonly used mic setup - SM-57 on the 12th fret of the acoustic, Peluso p28 on the soundhole, both mics about a foot away from the instrument, and the Kel Audio Large Diaphragm condenser capturing some room ambience. This yielded a nice sound, though not really resembling what i was hearing in the room. The 57 over-emphasized the upper mids, and the p28 was a little too "warm" and close sounding. I was pleased, however, to find that even with vigorous strumming it was immune to the boom and random resonances you often hear from other mics.

So I changed my approach, using a technique more often found in bluegrass and country settings - the Peluso over the player's  shoulder, pointed down at the soundhole where the pick hits the strings (about a foot away), and given the p28's warmth, the nt5 on the 12th fret a foot away (in case i needed to mix in additional brightness). This position really hit the spot - yielding a warm, natural sound with a little bit of roominess to it, with a smooth high end, that, due to the tube and careful positioning, avoided the terrible ice pick scrape sound. After a little tweaking, we were off to tracking. See clips 1-4 on the player below.

P28 Review by Colin Laflin

Next was the Mandolin - I used a similar position (why change what's already working?) to great results - see clips 5 and 6 - the p28 providing more warmth and body to the mandolin than what was actually present in the room! It really made a $300 dollar mandolin sound alot more expensive than it was. I added a little LA-2A compression to smooth out the high notes, and boosted a little 500-600hz to emphasize the "throatiness" of the instrument.

Next was the brushed snare part - a driving rhythm that runs through the song, we needed airiness without harshness or too much snap. I can't say enough about how well suited the p28 was for under the snare - 4 inches away from the bottom head, 45 degree angle, just slightly short of where the snares hit the head, taming what can often be a terribly NASTY snap of snares into a palatable "pit pat". Add a 57 on top for some body, and I had my snare sound. The clips you hear below have no compression or eq...the squish and gush you hear is all that beautiful little tube!

Just for fun, I tracked some shaker with the p28 as well - again, accurate transient response with the right amount of gush and swish, smooth, present highs.

I was thoroughly impressed with this mic - I will never, ever record another snare without trying one of these underneath. And the same goes for the acoustic guitar - unless I'm layering on top of a massive rock mix, I plan on having a pair of these around anytime I need to track acoustic instruments. Natural, warm, smooth high end, and immune to booms and harsh, scrapy highs. Nicely done, Peluso. The c451b's should be shaking in their shockmounts.

I should probably also mention that everything used in the recording - including the guitar and mandolin (with the exception of the Kel HM7U room mic) - can be rented at Rock n Roll Rentals!

In particular, all of this Peluso P28 goodness can be yours from Rock n Roll Rentals for the weekend rate of only 17 bucks!
