We all apperceive the complete of this effect: It replicates capricious degrees of the complete of arena your guitar in the gym showers, a cathedral, or Mammoth Cave, and it has accepted itself one of the a lot of atmospheric aural adulterations available. Aback none of those locations is absolutely gig friendly, however, our ever-handy techs accept bottled the acidity in a reliable, carriageable form. This class covers both answer and reverb effects, aback they are versions of the aforementioned thing. The appellation “echo” was acclimated added generally in the aboriginal days, and is sometimes acclimated today to accredit to the audible and abroad repeats of a signal, while “delay” refers to annihilation from the same, to the abbreviate repeats heard as reverb, to the complex, long, manipulated repeats of an intricate agenda adjournment line. Either way, they are both absolutely the aforementioned thing, just acclimated differently.
Analog Adjournment
The about-face of bulky, fiddly band answer units into transistorized analog answer pedals in the backward 1970s is arguably one of the greatest economies the delay-loving guitarists has anytime accomplished (physically added than financially). Players absorbed to annihilation from slapback to the anesthetic sonic cloning of their Echoplexes, Copicats, and Amplitude Echoes breathed aggregate sighs of abatement if Electro-Harmonix and MXR alien almost affordable analog adjournment pedals. By the aboriginal 1980s there was almost a rocker traveling who stepped on date afterwards a adjournment pedal, and every above furnishings maker offered a archetypal or two. Abounding players gradually absitively that their old band echoes in fact articulate bigger than the transistorized alternatives, but for Fulltone Band Echoconvenience account a majority of these still ashore with their stompboxes for reside work. Opinions on the tonal ahead of band echo—and abnormally tube-powered versions—have become even added angry in contempo years, breeding top prices in the acclimated bazaar and even the contempo alms of a Tube Band Answer from bazaar pedal maker Fulltone, but abounding still acquisition band impractical.
Like so abundant else, analog delays were aboriginal fabricated accessible by a about-face in the accessible technology in the mid 1970s, in this case the appearance of affordable adjournment chips. Techies alarm these “bucket army adjournment chips” because they canyon the arresting forth in stages from the ascribe pin to the achievement pin—with as abounding as from 68 to 4096 stages. Inject a signal, administer the acceleration at which it gets anesthetized from date to stage, tap the achievement and, voila, you’ve got echo. It’s bright from this that the added stages in the chip, the best the adjournment the ambit can achieve. The best the delay, however, the greater the baloney in the wet signal, so a lot of makers compromised to accumulate best settings aural adequate delay/noise ratios.
Electro Harmonix Deluxe Memory ManElectro-Harmonix’s Memory Man was one of the a lot of accepted solid-state delays ever, and even with its bare 5 to 320 milliseconds adjournment time was little abbreviate of advocate aloft its accession in 1976. At about $150, it was something of a bargain, too, admitting not bargain by any means—considering that at that time you could buy a new Stratocaster for just a little over three times that figure. The Memory Man was launched with Reticon SAD1024 chips, but E-H switched to quieter, bigger aural and added adjustable Panasonic MN3005 ICs if these became available, and the closing is the dent begin in the better-known Stereo Echo/Chorus and Deluxe models.
Different forms of abetment of agnate brazier army adjournment chips were aswell at the centermost of the added avant-garde choir and flanger pedals that emerged in the backward 1970s. With ICs that themselves were able of creating a controllable time adjournment in any accustomed signal, the job of harmonically modulating allotment of a split, delayed arresting to aftermath a warbling choir or swooshing border complete became a lot easier.
Digital Delay
The wonders of agenda adjournment accustomed on the pedalboard in the aboriginal 1980s with what seemed massive capabilities of continued delays, apple-pie arresting reproductions, and the amaranthine fun of one, two, or up to 16 abnormal of looping delay. In abounding cases, in the aboriginal days, reproductions weren’t absolutely all that apple-pie (or were cleaner than analog, but colder and harsher too), and abounding delays were decumbent to agenda baloney if pushed, or poor resolution on the adulteration of the signal. Even so, the techno-power of the new technology formed all over the basal of the old analog adjournment units, and for a time threatened to coffin them entirely.
Boss DD-7As for the basics and bolts of agenda delays, any thorough, from-the-ground-up account is added than can be entered into in this amplitude (and a lot of of you at atomic apperceive the basal assumption abaft bifold encoding by now anyway, right?). Simply anticipate of the agenda adjournment pedal as accession anatomy of sampler: it makes a baby agenda recording of your riff, and plays it aback at a user-selectable time delay, with abyss and amount of repeats aswell added or beneath selectable. The college the sample rate, the bigger the complete quality. Aboriginal affordable 8-bit models absolutely did leave a lot to be adapted sonically, but as 16, 20 and 24-bit designs emerged, the reproduction of the echoes added badly in quality.
As with so actual abounding elements in the abundant apple of guitar, however, already the change wore off and we were beneath afraid by the new technology—and, in abounding cases, came to apprehend that we had little use for 2 seconds, or even 500 milliseconds of adjournment time—many of us came to absence the warm, bendable complete of the analog pedals. Today, as with all such things, the board is still out; affluence of abundant players use anniversary blazon of pedal, and the music you accomplish with the technology charcoal added important than the blazon of technology you accept to use to accomplish music. Acclimated in isolation, at the aforementioned adjournment settings, anniversary would apparently complete just a little altered to a guitarist with acceptable ears. At the aback end of a pedalboard with eight or ten added furnishings on it and three or four active at a time, the differences are acceptable to be negligible—but altered players accept altered preferences, depending on what makes them feel acceptable about their tone.
Reverb
Achieved with springs or plates, as in the aboriginal days, reverb is a audible complete all its own. The aftereffect has been absorbed in to the adjournment affected added in avant-garde times because the aforementioned brazier army analog technology or agenda adjournment technology that is acclimated to actualize continued echoes can be manipulated to aftermath a reverb sound, too. Tap the multistage analog adjournment dent at a actual abbreviate delay, and band these with added such abbreviate delays, and a reverb aftereffect is produced. It has something in accepted with the bounce reverb in guitar amps—or old flat bowl reverb units—in that both almost the alveolate complete of a guitar played in an empty, cogitating room. While abounding players accomplish acceptable use of reverb pedals, including annihilation from Danelectro’s newer, far-eastern-built units to old and new Electro-Harmonix and Boss models, a lot of accede the amp-based, tube-driven bounce reverb to be the acme of the breed. But there are abounding abundant guitar amps out there with no reverb onboard, so for annihilation from your tweed Fender Bassman to your Marshall JTM45 to your Matchless DC30, an add-on assemblage is the alone option.
Fender Tube ReverbYou couldn’t alarm it a pedal, but Fender’s tube reverb, in its aboriginal or reissued form, has consistently been advised one of the best bounce reverb units around, and can be added at the foreground end of any amp (although this isn’t ideal if your overdrive complete comes from a channel-switching overdrive preamp placed afterwards the reverb). Added amp makers in the USA and the UK aswell offered stand-alone reverbs, affluence of which can complete absolutely fabulous. Fender was in fact a little apathetic accepting onboard reverb into its amplifiers, though, and makers such as Gibson and Ampeg offered combos with absurd aural congenital reverb in the aboriginal ’60s.
A bounce reverb assemblage is absolutely a baby amplifier in itself, that sends the guitar arresting through a tube ambit to a baby achievement agent (or through a transistorized circuit) and from there to one end of the springs in a bounce can rather than to a speaker. This arresting vibrates the springs, is best up by a transducer at their adverse end, and from there is attenuated aback with the dry arresting by degrees bent by a “depth” control, and beatific on to the achievement (or the ability tubes, if allotment of a guitar amp). As you can image, it’s a beefy aftereffect if accomplished in this way, acute at atomic a brace of transformers, two or three tube sockets and a bounce can, but the ambit itself is adequately simple.
Boss Agenda ReverbDigital reverbs, like their affinity delays, action added ability and a greater array of settings. And in accession to accomplishing some approximations of bounce reverb sounds, agenda units usually action added “lifelike” bang as heard in annihilation from an abandoned allowance to a ample concert hall, if you wish to add a actinic “natural” allowance complete to your arresting rather than alone carbon the archetypal sproing of springs. A few pedals do this actual well, but a lot of such accessories are arbor units that are best acclimated in an amp’s FX loop, and are above the ambit of this article. For all the ability of agenda reverbs, however, there are affluence of guitarists who just don’t balmy to them, and the tube-driven, analog, bounce reverb aftereffect charcoal hands-down the admired for guitar.
