A manufacturer of modular synthesis equipment, run by a collective of developers in the Czech Republic. Bastl offers a large line of mostly signal processing circuits in both tabletop and Eurorack formats. Most are available both assembled and as kits.

Bastl's design aesthetic is somewhat quirky. Many modules have fanciful and amusing names, and the company has used a number of different panel motifs. Current modules, as of the end of 2018, are being shown on the Web site with panels having an unusual faux-woodgrain background. Most modules have the electrical schematic symbol for an inductor drawn somewhere on the panel.
