Glockenklang is a German manufacturer of boutique bass amplification based in the Lippe region, with amplifiers designed and built by Udo Klempt-Giessing. The company began producing PA and hi-fi equipment in the mid-1970s and expanded into bass gear in the late 1980s. The name, which translates roughly to "bell sound," points to the reputation its amps have earned for clarity and articulation, and many European high-end bass luthiers use Glockenklang rigs as reference systems to reveal the character of their instruments.

The lineup covers amplifier heads, speaker cabinets, and onboard bass preamps. Amp models include the lightweight Class-D Steamhammer, the Blue Bird, and the Blue Bird Gold, with power ratings up to around 900 watts at 4 ohms and Class-A input stages. Cabinets are offered across the Space, Uno, Duo, Double, and Quattro series, alongside the Acoustic 8-2, and the electronics line includes 2-band and 3-band onboard preamps in standard and stacked-pot configurations. Products are built in small batches in Germany with a focus on component quality and long service life.

Glockenklang has a following among professional bass players in Europe and among touring musicians seeking hi-fi-voiced amplification. Reported users include Oliver Riedel of Rammstein, Helmut Hattler, and Rani Sharone of Stolen Babies.
