1)Input Jack - A 1/4-inch, 2-conductor input for plugging in your instrument. It’s intended for guitar but will work with other instruments as well.

2)Gain - Adjust this clockwise to increase the amount of distortion generated. Lower levels provide a blues-type tone, with higher levels delivering increased crunch - perfect for heavier music.

3)Gain On - This switch activates the distortion circuit.

4)Low - Controls the emphasis of bass frequencies. Turn counter-clockwise to decrease lows.

5)Shift - When activated, this control shifts the frequencies to emphasize midrange content. The result is a fuller, fatter sound.

6)High - Controls the emphasis of treble frequencies. Turn counter-clockwise to decrease highs.

7)Volume - Controls the overall level of the amplifier.

8)Headphone - A 1/4-inch input for headphones. Level is determined by the setting of the VOLUME control. Automatically disconnects speaker for silent practicing.

9)Jewel Light - Indicates whether the amp is OFF or ON.

10)Power - This switch turns the amp ON or OFF.

11)Speaker Output - This jack is for use with an external speaker cabinet. Minimum requirements: 8-16 Ohms, 12-Watts RMS or more.

NOTE:

#1. The internal speaker is disconnected when the external speaker jack is used.

#2. Using a speaker below the recommended 8-16 Ohms will damage the circuitry of your amplifier.

12) Line Output - This jack will deliver a line level output (Approximately 1 VRMS Maximum @ 1K ohm).

Tube12A specifications

The Kustom Tube12A is a powerful and versatile amplifier designed specifically for musicians seeking high-quality tone in a portable package. With its range of features and robust technology, the Tube12A stands out in the realm of live performance and practice.

One of the key features of the Kustom Tube12A is its all-tube design, which provides a rich and dynamic sound that solid-state amplifiers often struggle to replicate. The use of vacuum tubes not only enhances the tonal quality but also contributes to a natural compression that smooths out dynamic peaks, resulting in warmth and depth. Musicians looking for vintage tone can appreciate the Tube12A's ability to deliver classic sounds reminiscent of favorite amps from the past.

The Tube12A is equipped with a versatile EQ section, allowing players to tailor their sound with ease. It includes a three-band EQ consisting of bass, mid, and treble controls that provide substantial flexibility for shaping the audio output. Whether you prefer a punchy low end or sparkling highs, the Tube12A empowers users to dial in their ideal sound.

In terms of connectivity, the Kustom Tube12A offers a variety of input and output options. It features a 1/4-inch instrument input, making it compatible with a wide range of guitars and pedals. Additionally, a direct output allows for easy integration with recording equipment or P.A. systems, providing clear and reliable sound transmission for both practice and performance settings.

Another remarkable characteristic of the Tube12A is its portability. Weighing in at a manageable level, it is designed to be easily transported, making it an excellent choice for gigging musicians and traveling artists. The rugged construction ensures durability, allowing it to withstand the rigors of frequent use without compromising sound quality.

Moreover, the Kustom Tube12A incorporates innovative cooling technology that prevents overheating, even during lengthy sessions. This is particularly advantageous for high-output performances, ensuring that the amplifier maintains its performance integrity without succumbing to thermal issues.

In summary, the Kustom Tube12A is an exceptional amplifier that combines the rich tonal qualities of all-tube technology with flexible features and reliable performance. Its emphasis on portability, robust construction, and versatile sound-shaping capabilities make it a top choice for musicians of varying styles and genres. Whether for practice or live performances, the Tube12A continues to impress with its ability to deliver quality sound consistently.
