Duality / Duality RS

Home / Amps  / Duality / Duality RS

Duality is a combination of our knowledge of tone, in a super compact and transportable format. Duality has two channels. One three-dimensional clean channel, inspired by the most famous vintage single channel amps and one rich, harmonic distorted channel with multiple gain stages that makes it one of the most versatile amplifiers on the market today. Duality represents the cutting edge and can be used in any context and in any genre, covering any sound between the crystal clean and the most thorough lead.


DualityRS, introduced in early 2022, is a modified version of original Duality’s circuit. Due to its popularity, it’s now available and orderable from our catalog, anytime.
The mod consist in an overall increased saturation level, more pronounced top-end and a more compressed sound.  All variations from original design are exclusively to CH2 (distorted channel), while CH1 (clean channel) still the same.

Power amp section also is loaded with 6L6s tubes, instead of EL34.
New front grill and black knobs are aesthetic differences to recognize RS version from the original one.
