Singletone Amplification is a boutique amplifier and effects manufacturer based in Villa Bosch, Buenos Aires, Argentina. Founded in 2009, the company hand-builds bass and guitar amplifiers, effect pedals, and other tools for musicians one unit at a time, focusing on selected tubes, custom-wound transformers, and vintage-inspired voicings.

Their amplifier lineup includes hybrid designs such as the Moscow, which pairs a 12AX7 (ECC83) tube preamp running at high plate voltage with a Class D 50W power section and a blackface-style spring reverb, alongside other models like the Ohio and SLC. The brand also produces effect pedals such as the GULA, often demonstrated on their own video channels.

Singletone is a small, workshop-scale operation that ships handmade amps and pedals from Argentina worldwide. Their work circulates primarily through direct sales, the Reverb marketplace, and the Argentine boutique-amp community, where they are recognized as one of the country's notable tube-amp builders.

Singletone has 3 products cataloged on Equipboard, including Combo Guitar Amplifiers. Their gear is featured by 6 artists, with the strongest followings in Rock. Notable users include Richard Coleman, Jimmy Rip, and Tito Fargo.
