HOTONE Thunder Bass


The HOTONE Thunder Bass guitar amp head packs a powerful punch with its high-gain tone and compact design.



HOTONE was founded in Guangdong, China by a group of music enthusiasts and engineers with the goal of creating innovative and high-quality guitar amps and pedals. Among their products, the Thunder Bass is an amp head designed with the purpose of delivering the raw and powerful sound of a classic bass tube amplifier, in a compact and affordable package. In this article, we will take a closer look at the features and performance of the HOTONE Thunder Bass.

Design and controls

The Thunder Bass has a black and yellow color scheme, with a small and lightweight chassis that can fit in a gig bag or backpack. The front panel has a simple but effective layout, with four knobs and one switch for shaping the tone. The Volume knob controls the overall output level, while the Gain knob adjusts the amount of distortion and saturation. The three-band EQ section includes Bass, Mid, and Treble controls, each with a wide range of frequencies for fine-tuning the tone. Finally, the Bright switch adds a high-frequency boost for more clarity and presence.

The Thunder Bass also has a headphone output with a speaker simulator, allowing the user to practice silently or record directly into a DAW or interface. Additionally, the amp features an FX Loop for integrating external effects pedals or processors into the signal chain.

Power and sound

Despite its small size, the Thunder Bass packs a solid punch with 5 watts of pure Class AB power. This is enough to fill a small rehearsal room or coffeehouse with rich and warm bass tones, without sacrificing clarity or definition. The amp uses a 12AX7 tube in the preamp section, which contributes to the fat and crunchy sound of the overdriven channel. The tube can be replaced or upgraded easily, giving the user the flexibility to customize their sound further.

In terms of sound, the Thunder Bass delivers a classic and versatile tone that can cover a wide range of genres and playing styles. The Bass control can produce deep and rumbling lows or tight and punchy mid-bass frequencies, while the Mid control can emphasize or scoop the midrange for more presence or depth. The Treble control can add or cut the brightness of the sound, depending on the preferred style or instrument. The Bright switch can enhance the bite and clarity of the sound for slapping, tapping, or soloing techniques.


The HOTONE Thunder Bass is an impressive and affordable amp head that can provide a genuine bass tube tone in a portable and user-friendly package. Whether you are a beginner or a seasoned musician, this amp is worth considering for its simplicity, flexibility, and quality. Its small size and low wattage make it ideal for home practice, studio recording, or small gigs, while its powerful and versatile sound can meet the demands of various genres and situations. The Thunder Bass is a proof that good things come in small packages, and that HOTONE knows how to deliver them.

Frequently Asked Questions:

How does the implementation of HOTONE's Accu-Notch technology in the Thunder Bass Guitar Amplifier Head result in a more natural and articulate bass tone?

The Accu-Notch technology used in the Thunder Bass Guitar Amplifier Head by HOTONE involves analyzing the frequency response of a specific type of unwanted feedback or noise, commonly known as "mud" in bass amplification. The algorithm then creates an exact notch filter that eliminates this specific frequency range without affecting the desired frequencies in the sound. This results in a clearer and more natural tone with enhanced articulation and definition, particularly at high volumes where feedback is most common. By implementing Accu-Notch technology, the Thunder Bass Guitar Amplifier Head provides bassists with a more versatile and refined amplification solution.

How does the HOTONE Thunder Bass guitar amplifier head's dynamic bass boost circuit enhance low frequencies without introducing unwanted noise or distortion?

The HOTONE Thunder Bass guitar amplifier head features a dynamic bass boost circuit that utilizes a specially designed class-A topology to enhance the low frequencies of your bass signal. This circuit is designed to provide up to 18dB of gain at 40Hz, without introducing any unwanted noise or distortion. To achieve this, the circuit employs a high-quality discrete op amp and a custom low-pass filter. The filter helps to maintain the clarity and definition of the bass frequencies, while the op amp provides clean gain with very low noise. The dynamic nature of the circuit means that it responds quickly to changes in your playing dynamics, providing increased punch and impact when you dig into the strings. This makes it especially useful for playing styles that rely heavily on low-frequency content, such as slap bass or heavy metal. Overall, the Thunder Bass's dynamic bass boost circuit offers a powerful yet transparent way to enhance your low frequencies, making it an essential tool for any bassist looking to add some extra punch and clarity to their sound.
