Cooper FX has just announced Arcades, a guitar pedal that changes its tune with SD card-sized swapable cartridges. Inspired by vintage video game consoles (hence the name) Arcades aims to negate some of the cost involved in traditional pedals -- the bulk of which comes from hardware such as knobs and switches -- by giving musicians a brand new effect for a lower price. Just pay for the cartridge, which will cost from $30 (around £24), depending on which one you go for. The pedal itself costs $330 (about £265). In a blog post, Cooper FX explains that getting Arcades to fruition has "been a real uphill battle," not least because manufacturing is situated in Wuhan -- the center of the coronavirus outbreak.
