Skrydstrup R&D is a Danish manufacturer of guitar and bass electronics founded in 1997 by electrical engineer and musician Steen Skrydstrup, based in Egtved, Denmark. The company built its reputation by designing custom switching systems, MIDI controllers, and rack rigs for touring professionals, with past credits including work for David Gilmour, The Edge, Steve Morse, Rammstein, Biffy Clyro, and Scorpions.

Its product line spans bass and acoustic guitar preamps (such as the BP1 and AP1 series), the BAS1 and ACC1 systems, the BC1 bass compressor, switching systems, and MIDI foot controllers, all handcrafted in Denmark. The company now markets its consumer-facing pedals and preamps under the Caveman Audio by Skrydstrup brand, while continuing to build custom rigs for professional artists.

Skrydstrup has 8 products cataloged on Equipboard, including Guitar Amplifier Heads, Buffer Pedals, and MIDI Foot Controllers. Their gear is featured by 10 artists, with the strongest followings in Rock and Metal. Notable users include Matthew Bellamy, David Gilmour, and The Edge.
