Ramble FX was a boutique guitar effects pedal company based in Minnesota City, Minnesota, founded and run by builder Tim Krueger. The brand hand-assembled analog pedals in the USA and earned a reputation in the boutique community for meticulous design and carefully voiced circuits rather than high-volume output.

The lineup centered on a handful of distinctive pedals. The Twin Bender is a two-in-one fuzz that combines Sola Sound Tone Bender MKII and MK1.5 circuits in a single enclosure, while the Marvel Drive is an overdrive built around dual JFET gain stages that aims to capture the voicing of a cranked Marshall plexi. The Kismet rounds out the catalog as an analog overdrive/distortion with a digitally controlled preset system, pairing a fully analog signal path with recallable settings.

Following Tim Krueger's death in July 2022, Ramble FX ceased operations, making its pedals sought-after items on the secondhand market.

Ramble FX has 5 products cataloged on Equipboard, including Overdrive Effects Pedals, Fuzz Effects Pedals, and Distortion Effects Pedals. Their gear is featured by 5 artists, with the strongest followings in Rock and Blues. Notable users include Chris Buck, Joe Satriani, and Neal Schon.
