It may seem counterintuitive at first glance, but using a guitar amp on a silent stage provides several advantages. It’s a great help if the sound technician is late or if you want to warm up while the PA or IEM system is being set up. It gives you options if the house PA or backline isn’t the greatest and needs a boost. Although many pros have switched to modelers for gigging and even recording, you may be concerned about sacrificing the inspiration that the tubes in your amp provide. Or you simply may not have time to learn to work with unfamiliar gear. Besides, some sound engineers prefer to have low volume on the platform during softer songs to hide distracting stage sounds such as drumstick strikes on electronic drum pads. These solutions allow you to shred your guitar, not your cochleas! Acoustic Isolation Solutions ClearSonic ClearSonic provides three levels of portable isolation to rein in the volume of your tube amplifier without compromising your tone or hindering your access to its controls. Keep your amp’s visual impact with the AmpPac 10’s combination of acrylic panels and proprietary Sorber baffles. The AmpPac 21 amp isolation package steps it up with additional Sorber baffles to encircle your amp while keeping control-panel access and mic placement easy. For speedy absorption, quiet your amp with ClearSonic’s portable gobo — fold it in half to double its thickness or combine multiple units with the included hook-and-loop straps. The built-in hand strap makes transportation easy, and the unit can be reversed to create a livelier sound.

With a tighter low end, your speaker will sound less muddy so you can keep the volume lower. Add to cartLearn MoreAdd to list Rivera Silent Sister Rivera’s vented Silent Sister isolation cabinets cut your volume by approximately 30 decibels, isolate your guitar mic from outside sound, and allow your speaker to breathe and behave as if in an open room. Each model comes with mic clips, goosenecks, and XLR outputs. Choose from speakerless (so you can add your amp’s speaker), a preinstalled 12-inch Celestion Vintage 30, or a preinstalled Celestion G12T-75 speaker.

You can use an attenuator with most amp heads and some combo amps. Insert the attenuator between the amp’s speaker output and the speaker’s input. On a combo amp with hard-wired speakers, you can still use an attenuator by having a Sweetwater technician install a speaker jack on the amp. Whether you have a combo or a head, if your attenuator has a load box feature, then you do not need to connect the speaker. This is very helpful for amp head use because you no longer need to lug a speaker cabinet to the gig. All the models in this list are attenuators, so you’ll be able to get your tube amp’s full crunch character at quiet or silent levels. Some models reduce that level incrementally, and others give you a knob to dial the stage level you want. Some models are also load boxes, which means they supply a load to your amp so that the speaker doesn’t need to be connected. Some models include such helpful bonus features that you may use the unit even when you don’t need attenuation. Attenuator vs. Load Box An attenuator reduces the output level of a tube amp between the power section and the speaker. This allows you to fully drive a tube amp’s preamp and power sections to get all that glorious saturation at a comfortable listening level through your amp speakers. A load box enables a tube amp to operate without damage while disconnected from a speaker. Some hybrid models function as both an attenuator and a load box. Amp Wattage Rating An attenuator or load box power rating must meet or exceed the tube amp’s peak output, including when it’s overdriven into saturation. Play it safe with an attenuator or load box rating that’s higher than your amp’s nominal power. Outputs All attenuators — including the ones listed here — insert between your amp and speaker. But for a silent stage, you need an output that can connect to your sound console either directly or through a snake, DI, pedal, or other unit. Some models on this list provide extra outputs so you can connect your amp to a speaker, DAW, pedal, secondary amp, or other gear. Some models feature dual wet/dry outs, and a couple units include stereo outputs. Headphone Outputs Some models provide a headphone output. This is handy for checking your signal, troubleshooting, or warming up before a gig. IRs & Modeling Some of these models offer you different digital or analog cabinet-modeling options. Many allow you to pick from multiple impulse responses (IRs) or even add third-party IRs. Some models offer virtual microphone selection, mic placement, and room ambience. Effects & EQ Some models provide reverb, compression, boost, doubler, gate, or other onboard effects. Some models additionally offer presence knobs or an EQ to shape your sound at one or multiple points in the signal path. Effects Loop In/Out Some tube amps lack an effects loop. Attenuators with this feature allow you to insert pedals between your amp’s preamp and speakers, even when not attenuating the volume. This is a great way to add ambient, wet effects such as reverb and delay. App Control Some models allow you to use an app to make recallable deep-dive adjustments to your settings. Connection options vary between using a cable or Bluetooth wireless. Footswitch Output Some units have a jack for a footswitch or controller. Impedance Selection Your amp or cabinet could be damaged if your attenuator does not match your amp speaker’s impedance rating (4 ohms, 8 ohms, 16 ohms). Certain models output only a single impedance (ohm) rating, but others allow you to switch between multiple impedance levels. Additionally, a few models allow you to input and output at different impedances, which enables you to use the unit as a transformer between mismatched amps and speakers. Attenuators: Notch Down the Noise Do you need just enough stage volume to cover ambient noise such as stick strikes on electronic drum pads or squeaky piano pedals? Check out these power-soak attenuators. Keep all the dialed-in tube tone of your miked amp while bringing down stage volume to a manageable whisper! Dr. Z Brake-Lite Standalone 45-watt Attenuator For tube amps up to 45 watts, the single-knob, set-and-forget Brake-Lite may provide a perfectly simple solution. Insert the Brake-Lite between your amp and cab. Then select from five levels of attenuation — setting it to silent is like having a handy mute switch at your fingertips. You can input 4-, 8-, or 16-ohm loads and run multiple 4-ohm (or greater) cabs simultaneously. The Brake-Lite is an easy answer for cranking out great tone through the PA without ruffling feathers onstage! Add to cartLearn MoreAdd to list SPL Reducer Passive Power Soak SPL’s tonally transparent Reducer addresses one challenge really well. Crank out all the meticulously crafted drive you can muster from your amplifier — up to 200 watts* — and the Reducer outputs only the volume you need to your 4-, 8-, or 16-ohm cabinet without breaking a sweat. Plus, because this little workhorse is completely passive, no additional power supply is needed. *Up to 200 watts at 4 or 8 ohms; up to 120 watts at 16 ohms. Add to cartLearn MoreAdd to list Rivera Attenuators & Load Boxes Tame your volume without defanging your tone by selecting one of these options from Rivera. The RockCrusher and RockCrusher Gold Face handle amplifiers up to 120 watts at 8 or 16 ohms and drastically reduce your speaker cabinet’s volume. In addition to outputting to one or two cabinets, you can send to your sound console through the XLR out or to a pedalboard or computer interface through the unbalanced output.

Check out these models that you can run silently. Universal Audio OX The Universal Audio OX reactive amp attenuator provides a solution that silent-stage tube-amp players will appreciate. Plug in an amp that outputs up to 150 watts of peak power and dial down the volume to a whisper or nothing at all. The OX is also a load box, so your cabinet can skip church and sleep in. Shape your tone by accessing dozens of included UA microphone and guitar-cabinet emulations. Load up to six of your favorite rig presets and add multiple onboard EQs as well as compression, delay, and reverb effects.
