The ID:Core 10 V4 is a neat little practice amp, especially if you’re just starting out or need something super portable. It’s a good way to get a taste of Blackstar’s amp tones without a huge investment, but don't expect flagship-level sounds or a massive range of amp models. It's best suited for bedroom practice and quiet jamming.

The ID:Core 20 V4 is a seriously clever little amp. It's a fantastic grab-and-go solution for bedroom players and gigging musicians needing a versatile, affordable practice amp. The range of sounds is surprisingly good, especially if you're into classic rock and modern high-gain tones, but keep in mind the small speakers limit the low-end thump.
