Creative Cabinet Choices
Ever wonder what a Superlead would sound like through an AC30 cab but were afraid to try for fear of blowing the Celestion AlNiCo Blues? Once again, as long as the impedance is set correctly, and the power is scaled back to accommodate the speakers, who says you have to use the same cab as the head was designed for? Many times I’ve been in the studio and knew that the tone of the amp was dialed in, but wanted a different color. Rather than running the typical, closed-back 4x12, I was able to choose between the many different cabs available by attenuating the signal down enough to allow safe operation. It’s a great way to experiment with tone and to further lessen the volume assault. This is great for live situations as well. Imagine how much easier it will be on your back to carry in a 1x12 cab for the gig. Heck, you usually only mic one speaker anyway. You can still get raging tone, just in a smaller footprint (physically and sonically).

Dummy Load/Line Out/Speaker Simulator
For recording or the ultra-adventurous live guitarist, how about ditching the cab altogether? These days with the myriad amp modeling programs and hardware devices, who says you even need a cab to produce a mic’d speaker tone? Dedicated devices like the Hughes & Kettner Red Box, the Palmer PDI-series of speaker simulators and the fabulous Axe-FX all offer ways of attaining a variety of speaker tones without speakers. As long as you have a dummy load and line out on the attenuator you can accomplish this easily. After setting the attenuator to “load,” take the line out and feed it directly into the hardware unit. The Red Box Classic offers settings for “combo” and “4x12,” while the Palmer offers an 8-ohm dummy load and multiple settings to simulate a variety of speaker configurations. Highly detailed speaker cab emulations as well as microphone models, reverbs and more can be obtained with the Axe-FX by Fractal Audio Systems.

If you’re in a recording scenario and like to use modeling software, consider bypassing the amp models and just use the mic and speaker models. The variety of software amp modelers is vast with, more products entering the market all the time. Each one of them has its own sound and the options are nearly endless. You’d be surprised how good they sound, and with the no-speaker option you can record at 2 a.m. with your favorite amp. Better yet, if you fire up the studio the next day and don’t particularly care for the sound of the mic/cab combination from the night before, you can change it, because the only thing that was recorded was the tone of the amp. For much more detailed information check out the article, “Look Ma, No Speakers!” in the July 2008 issue of Premier Guitar.

These are just a few options you can try out with most current production attenuators. There are certainly many more not covered in this article that would be helpful, but there’s only so much space available. The possibilities are endless. That said, we are in a new era of amps and tone, with more amplifier options than ever before. And while amp builders are certainly conscious of designing new amps with lower wattage and features such as power dampening or power scaling, we do still love our high-powered amps. Most of us won’t have the opportunity to play Madison Square Garden anytime soon, nor do a lot of us have amp rooms where we can crank our rigs up and jam without consequence. That’s why the attenuator is such a great device. Not only does it act as a big volume knob, it serves us in many creative ways… your imagination is really the only limit with what we have available today.

I loved this article, I was using my THD in the regular way and liking it, but using the line out wet/dry method I keep all of the tone as well as taming the volume. Maybe they should market an attenuator with a built in power amp just for this application.......althogh slaving does look kind cool.

Without the time to spend trawling the web this article provides a truly great resource. I arrived the 'long way' round (weeks on the web). My 1969 Fender "Bantam Bass - Amp" after I gave it the restoration it needed (new caps & valves etc.) came back to life; and like other early Fender bass amps it makes a fantastic guitar amp - 6L6 'mayhem' with no 'master volume'. Set the volume at 3 (it's only a 30w amp) - stuff in the room start to 'rattle' but it has that great 'classic' Fender 'clean' sound; however, the amp really comes to life (for guitar) with the volume at 6. treble at 6. middle at 3 and bass at 2 - at this level stuff falls off the shelves - literally, and my ears are saying "this ain't 1974 no more!" . After more research I got a 'Weber Mass Lite 100' (on blind faith - US to Ireland). I figured that the dynamics of an actual speaker mechanism made sense; and I can say that it has made a real beauty of this beast. With the attenuator I can now drive the Normal channel at 6 (classic clean), then blend in the bass channel (this amp's circuit enables both) from 3 (biting) to 6 (saturated sustain) and my kids can do their homework in the next room without hearing me! 'Taming of the Beast' ? at small club gigs I can always get the right level; and always with near perfect sound from this vintage amp... very happy days! Thank you T.A. Weber.

Great article. Probably the best attenuator that should have been mentioned is the Faustine Phantom. It not only works for all impedance levels but, what is more important, it is absolutely transparent. No weird artifacts or tone degradation whatsoever! A rare feat indeed. The favorite among the LA guitar ace and studio scene.

Great article! I have been using a THD Hotplate for quite a while now and lately, I have been using my tube amps with the hotplate line out into my DAW and using impulse response files for my mic and cabinet sounds. Add a touch of ambience/reverb and the tone fits my needs. Great setup for those with finicky neighbors or infants trying to sleep in the next room.

A very well written article. I have found myself trying out all the low wattage amps that have flooded the market in the last few years, always returning to my 50 and 100 watt Marshalls. As nice as many of these low wattage amps sound, to me they leave me wanting, they still FEEL like a small amp and the tone may be great in them but it still has that practice amp feel. Enter my precious attenuators. (mostly hotplates) I have used many of the techniques the author has described for many, many different needs and I find that while, yes they do leave their fingerprint on the sound, it's ever so slight that I hardly notice. But, I DO notice the difference between a maxed Rebel 20 (or many others of this type) and my JCM800 dimed but, attenuated to bedroom volumes. The difference is not only in the tone but, especially in the SIZE of the tone. I could put both the above amps side by side and match the decibel level and I guarantee the Marshall would give you a tone that was much bigger and still reminded you of the tone coming out of the JCM800 dimed with NO attenuator. I've been using them for quite a few years on a lot of different amps, both vintage and new and have NEVER experienced any kind of problem with the amps I've used them on. Like the author says, you have to make sure there are no pre-existing issues with your amp first and that it's biased correctly, etc. I've also tried out quite a few of the newer lower wattage amp offerings out there, and they're a lot of them that deserve their dues,sound great and get the job done, especially when it comes to looking for variety in the studio, but when it comes to live sound whether it be for a gig or just for me, give me a 100watt Marshall, Orange, Mesa, Bassman, etc. running full out, balls to the wall, with that big attenuator knob to tame the storm! I didn't get into how versatile these can be and I won't because I've said more than my share already, suffice it to say you have more total options of things you can

I use a Weber mini mass on my Fender hot rod deluxe. It works great, and sounds better (to my ears) than other attenuators. Lets me run the amp on full power to get some very tastey output tube distortion, which sounds different than just cranking up the gain on a master volume tube amp. Pre-amp tube distortion and output tube distortion can be played with and blended through the use of an attenuator.

BTW - The Weber model uses a speaker motor inside the attenuator to create a dynamic speaker-like load. Most other attenuators just use a fixed load. The webers are more dynamic than other attenuators I've tried.

I must have DNA blockers that kick in anytime I hear or see the word "electricity". I have what is possibly an irrational fear of blowing up my amp, among other things.
