Master Volume
The master volume on the front panel has been superbly implemented to maintain the amplifier's tonal characteristics even at very low volumes. This allows you to practice quietly without sacrificing the rich, dynamic sound that defines the "Zircon," making it ideal for both late-night practice sessions and intimate recording environments.
Exceptional Pedal Compatibility
The "Zircon" sounds extremely good on its own, delivering rich, dynamic tones right out of the box. Moreover, it has excellent compatibility with effects pedals. Whether you’re using overdrive, distortion, Fuzz, delay, modulation, or any other effects, the "Zircon" handles them all with ease, maintaining clarity and enhancing your tonal palette. This makes it an ideal choice for guitarists who rely on a variety of pedals to create their signature sound.
HIGH/LOw Voltage SWITCH
This switch allows you to select between low and high voltage settings, enabling you to replicate the feel and response of vintage amplifiers. In the low voltage setting, the amplifier produces a more compressed, softer sound, ideal for achieving classic vintage tones. The high voltage setting provides a more dynamic and responsive feel, perfect for modern playing styles and higher output
Negative Feedback
The "Zircon" also features a three-position negative feedback rocker switch, allowing you to adjust the amplifier’s overall response and feel. This switch lets you tailor the amp’s dynamics and sensitivity, providing more or less negative feedback to suit your playing style and preferences.
Adjustable Digital Bias
The "Zircon" includes an adjustable digital bias feature, giving you precise control over the tonal characteristics and response of the amplifier. Fine-tune the bias to achieve your perfect sound, from tight and focused to warm and dynamic, making it ideal for replicating the expressive and dynamic tones of Philip Sayce and SRV.

Impedance Selector Switch
Another versatile feature is the three-position impedance selector (2-4-8 ohms), which provides flexibility in matching the amplifier with different speaker configurations. Whether you want to connect a 4x10 cabinet or a 2x12 cabinet with 8-ohm speakers, the "Zircon" ensures optimal performance and compatibility.
Rough Overdrive Function
Three Toggle Switches
On the front panel, three toggle switches provide fine-tuned control over your sound in a style reminiscent of Dumble amplifiers. The first switch is a three-position treble switch, allowing you to shape the high frequencies with precision. The second switch is a boost switch, perfect for adding extra power and presence to your signal when needed. The third switch, inspired by the famous Dumble jazz/rock switch, lets you toggle between two distinct voicings, enhancing the versatility and adaptability of your tone.
The innovative "Rough" function allows you to add overdrive to your signal with the simple push of a button. Whether you need a gentle boost for a solo or a gritty, saturated tone for rock riffs (Marshallish), the "Rough" function provides versatile overdrive options to suit any style, particularly excelling in delivering the powerful, soulful overdrive that characterizes the rock blues genre.
PENTHODE/Hi-Fi Switch
The second rocker switch offers a choice between pentode and hi-fi (ultra-linear) operation. In the pentode setting, the amplifier operates in a traditional tube configuration, delivering the warm, saturated tones that guitarists love. The hi-fi setting, adjustable between 20% to 40%, provides a cleaner, more linear response with reduced saturation, giving the amplifier a more precise and controlled sound suitable for various musical applications. This hi-fi setting is particularly suited for achieving the clear, articulate tones associated with Stevie Ray Vaughan when he played through Dumble amps.
Three-Position Gain Switch
One of the standout features of the "Zircon" is its three-position gain switch, offering three distinct levels of gain. This switch allows you to effortlessly transition from a clean, pristine "blackface" tone to a crunchy mid-gain sound, and finally to a super powerful, overdriven tone reminiscent of Stevie Ray Vaughan’s iconic sound. This versatility makes the "Zircon" perfect for a wide range of musical styles and playing techniques.
Vintage Reverb
The "Zircon" features a superb vintage-style reverb, meticulously designed to replicate the lush, expansive sounds of classic spring reverb. From subtle ambiance to deep, immersive echoes, this reverb adds a unique character to your sound, perfect for creating atmospheric and dynamic performances.
Ornate Front Grill
The front panel of the "Zircon" is a work of art in itself, featuring a stunning ornamental design that combines intricate paisley patterns with rich, opulent colors. The detailed motif showcases a blend of swirling floral elements and bold, vibrant accents in gold, blue, and cream, reminiscent of luxurious vintage fabrics. This decorative element not only enhances the amplifier’s visual appeal but also evokes a sense of classic elegance and refined taste. The aesthetic and color scheme of the front panel are carefully selected to echo the beauty and brilliance of the zircon gemstone, creating a cohesive and thematic design.
Advanced Features
The "Zircon" includes three rocker switches on the rear panel, each adding unique tonal shaping capabilities that replicate the characteristics of vintage amplifiers.
The "Zircon" is a testament to exceptional sound engineering and elegant design. It offers musicians an unparalleled combination of vintage warmth, modern versatility, and timeless beauty.
