Decoud, also known as Decoud Hermanos, is an Argentine amplifier manufacturer based in Villa Ballester in the greater Buenos Aires area. The company has been producing instrument amplification for decades, with players recalling tube-based Decoud rigs dating back to the 1970s, and operates as a workshop-style factory that turns out a high volume of affordable, locally-built gear for the domestic market.

The brand's catalog focuses on budget-to-midrange combo amplifiers, heads, cabinets, and active PA-style boxes for guitarists, bassists, and general musical use. Models commonly seen in Argentine shops include the RS-series guitar combos (such as the RS-26 and RS-40), the multi-purpose MO line (MO 40, MO 70, MO 120) with USB/SD/MP3 inputs and tweeters, the HB-series bass combos, and the valve-driven Valvetech BT40 B for bass. Decoud Hermanos also manufactures amplifiers under the related ElectroVox, Valvetech, and Nativo names from the same facility.

Decoud sits firmly in the Argentine national-manufacturer tier — the same ecosystem as brands like Tregar, Marshou, and Plimsoul — and its products are distributed almost entirely through Argentine music retailers and online marketplaces rather than through international export. The amps are widely used by students, working musicians, and rehearsal rooms across the country who want serviceable home-built gear at accessible prices.

Decoud has 2 products cataloged on Equipboard, including Combo Guitar Amplifiers.
