The overload effect emphasizes the treatment of vacuum tube power amplifier, not the effector itself. It keeps the original timbre of the guitar more than distortion, and it enhances the signal to drive the vacuum tube power amplifier circuit more effectively, rather than pre-amplification distortion processing. A typical example is the TUBE SCREAMER TS808(TS9) by IBANEZ, which is also Vaughan's signature voice.
Therefore, in order to get sweet overload timbre, it is necessary to use all-vacuum tube speakers or power amplifiers, and it is better to add a compressor before overload. This effect is to enhance the bass before signal processing, attenuate part of the midrange, and produce a fuzzy sound after distortion. Jim Hendricks' performance is a good example, and LED ZEPPLIN was often used in the early days.
The easiest way to get Faz timbre is to use the pickup at the neck of the guitar (set the pickup selection switch to the highest grade), turn down the timbre control knob and play near the neck, so as to get more bass and less treble.
The classic representative of hair effect device is the electric harmonica muffin effect device.
The general distortion effect device of power tube emphasizes the timbre processing in the pre-amplification stage, and there is no power amplification distortion. The signal is distorted by average and then shaped by EQ, and the tone with general distortion is obtained.
To evaluate the quality of distortion effector, we can't judge its effect only by using it alone. The best way is to add a graphic equalizer before and after the distortion effect device to judge whether the effect device can get a wide range of pleasant distorted timbre. A good distortion effector can produce a good timbre when balancing the curves before and after distortion, and a poor one can only produce a better timbre when balancing the curves.
A typical example is the distortion modeler DM-4 of Line 6.

I don't know how to describe this timbre. If you have heard the album van halen 1, you will know something about this timbre. In fact, it is a combination of semi-preamplifier distortion and semi-amplifier distortion.
Saturated pedal tube explosion distortion effector
The distortion of tube explosion emphasizes the distortion caused by pre-amplification of vacuum tube. His design concept is to use the preamplifier vacuum tube as the power amplifier vacuum tube to drive a dynamic load. Such as h &；; K CRUNCH MASTER and adaamplifier.
Unfortunately, people have stepped into a misunderstanding because they are touted by dealers: they think that using this effector can produce distorted timbre like a real vacuum tube power amplifier, and overestimate the role of this effector.
In fact, as far as preamplifier distortion is concerned, the timbre produced by vacuum tube and transistor is not far apart. For power amplification, vacuum tubes and transistors are completely different!
