The Blackstar HT Studio 20H lets you dial in a huge number of tones in a compact head, perfect for recording, rehearsal and small club gigs. This valve-driven top starts with two footswitchable channels, going from shimmering clean sounds to crunchy drive and all the way into fat, saturated lead sounds. Blackstar's patented "ISF" control lets you variably dial in a world of tone, from vintage British crunch to modern American distortion, with some wild hybrids in the middle. When it's time to record, get super hot sounds at lower volumes with the Master Volume control, fill out the sound with the studio-quality digital reverb, and even leverage the speaker-emulated output to blend in direct sound with what the microphone captures.
