Double-angle channeled aluminum edging with .0625" extruded walls sized to fit case panels. Panels are fabricated of 1/2" AC exterior grade plywood, laminated with 1/16" thick ABS industrial plastic (various colors available - black standard). Interiors are lined with high density foams.

A Jackson Ampworks Exclusive! - Jackson Ampworks is the first amplifier manufacturer to offer an accessory compartment built right into the flight case! By having this accessory compartmentavailable, items like, power cords, speaker cables, power attenuators now have a safe and logical place to be stored.

Double tongue-and-groove channeled aluminum valance with .0625" extruded walls sized to fit case panels. Valance mating tolerances provide protection from dust and water, eliminating the needfor rubber gaskets.

Spring-loaded handles feature a large rubber grip in a recessed zinc plated steel dish.

All cases have either zinc-plated steel stacking ball corners or stacking flat corners so like cases nest and stack on one another.

Spring-loaded, snap-back hook with over-the-lid strike allows case valance to remain one piece and permits the case to be water or air tight.

Full length hinge provides seamless support and more road worthy performance.

Side mount hinges hold the lid upright when the case is opened which allows for easier access to the cases contents.

The THD Hotplate is one of the finest power attuators on the market today. With a host of features at its disposal, it is by far the most comprehensive power attenuator on the market and its tuned network closely emulates the actual reactance found when driving a speaker cabinet!

A power attenuator is a device placed between the speaker output and the speaker cabinet. It acts like a huge master volume control and permits the amp to be turned up most or all the way while absorbing most of the power generated by the amplifier and turning this power into heat. It passes a small part of the power to the speaker.

Our customers use attenuators because their amps sound good at high volumes, especially with full distortion, but in rehearsal, small clubs, or at home, they can't turn the amp up. They are also used in recording studios for better separation between the instruments, and for use when the speaker sounds best at low levels, or if it can't handle the power output. The Hot Plate also makes a perfect dummy load.

A THD Hot Plate is a tuned network of capacitors, resistors and inductors which adjusts the overall EQ as the volume is turned down to compensate for the human ear's frequency response. Your ear perceives sounds differently at different volumes: the louder the sound, the more sensitive your ears are to highs and lows. As the volume drops, your ear becomes more sensitive to the mid-range, and less so for highs and lows. The Hot Plate compensates for this, working like the "Loudness" switch on a hi-fi. The THD Hot Plate is the first, and for now, the only attenuator that is frequency compensated.

The THD Hot Plate is designed for use strictly with vacuum tube guitar amplifiers, and each version is optimized for a specific impedance (2, 4, 8, or 16 ohms.) These inductive loads are frequency compensated, which means it will give you the best possible sound for that impedance speaker and amplifier combination.

To use one: Connect the speaker output of the amp into the input of the Hot Plate, then connect the speaker cabinet to one of the two speaker outputs of the Hot Plate (doesn't matter which one). The amp thinks the Hot Plate is a speaker, so the sound stays true even when you turn the volume down.

Built-in Noise Reduction
The THD Hot Plate is the only attenuator on the market with built-in noise reduction to reduce the hiss and hum between notes. A passive, single-ended noise reduction system which provides approximately 10 dB of broad band noise reduction without gating or pumping, and without affecting the tone of the amp. A by-product of the noise reduction circuit is that it generates light as you play. The harder you play, the brighter it glows.

Tone Controls
The Hot Plate is also the only attenuator offering a Bright switch and a Deep switch for tailoring your sound. The Bright switch gives you two different high frequency levels so you can compensate for an overly bright, or dull speaker cabinet. The Deep switch offers two distinct bass settings to help you fill out the bottom end, or reduce the bass in a cabinet with too much low end.

Adjustable Line Out
THD Hot Plates also feature a Line Out, which is adjustable by its own volume control giving it a wide range of applications. At higher settings, it can provide enough signal to drive the input of a separate power amp for slaving. The middle range of settings is useful for most rack mount effects. And turned most of the way down, the Hot Plate's Line Out will drive the instrument input of another guitar amplifier for extra power and volume.

The THD Hot Plate will not damage your amplifier. When you play continuously at full output, you cause your tubes to age more quickly than they would at lower volumes. Using a Hot Plate will maintain the life of your tubes at exactly the same rate, no more or less, as when you play straight through the speaker.

Using a Hot Plate will also not hurt your transformer any more than playing through a speaker, as long as the impedances are matched (i.e. 8 ohm setting on the amp, 8 ohm speakers and an 8 ohm attenuator). If you are using a well-made amp, then the transformer should last indefinitely, regardless of whether you are driving a speaker or attenuator. If you are using an inferior amp and the transformer blows, it would have done this whether you play through a speaker or an attenuator. The Hot Plate puts the same load on the transformer as a speaker (which is why it makes such a good dummy load)

You can order a THD Hotplate available in 2, 4, 8 and 16 ohm versions online at the Jackson Ampworks Store.

The Weber MiniMASS Power Attenuator is similar to the THD Hotplate, except that the Weber Mini-MASS speaker load incorporates a loudspeaker as the load. It is not a fan motor with inductors, capacitors, and resistors, it is an actual loudspeaker. With that, you get a dynamic load reacting with the output of the amplifier it is connected to. All of the complexity and variations in frequency response and impedance occur with the MASS since the speaker motor exhibits physical movement. Therefore, the MASS is just like connecting to a speaker, only the MASS is quiet. The MiniMASS comes standard with a switch for selecting either 4, 8, or 16 ohms, as well treble compensation, a bypass switch, and a line out tap for slaving to external FX processors or power amps. Because of the unique design of the MASS, the speaker may be disconnected entirely when the MASS volume control is set at minimum. This allows the MASS to serve as a dummy load for testing amps, DI-only use, etc.
