Blackstar · amplifier
The Blackstar ID:Core 40 V3 is a 40-watt stereo solid-state guitar combo amplifier with six onboard amp voices covering clean warmth through crunch and high-gain saturation. Blackstar's Super Wide Stereo processing expands delay, reverb, and modulation effects into an impressive spatial soundstage from the dual-driver format. The ISF tone control shapes American-to-British tonal character. Six onboard effects categories cover modulation, delay, and reverb. At 40 watts it covers home practice and quiet rehearsal. The V3 generation improved voice modeling clarity and effects quality over the V2, establishing the core feature set that the V4 further refines.
