Blackstar HT Studio 20 - 20W Tube Amplifier Head

The HT Studio 20 Head from Blackstar is a 20W tube amplifier for guitar that uses two EL34 power tubes and two ECC83 preamp tubes, and has two footswitchable channels with built-in digital reverb, an effects loop with a level control switch (+4 dBV or -10 dBV), a 12" Celestion speaker, as well as a stereo speaker emulated out for recording or driving headphones. Blackstar's proprietary ISF (Infinite Shape Feature) circuit works in conjunction with the tone control for fine-tuning, so you can effectively dial in the specific sound you desire. Its small size and versatile features make the HT Studio 20 an ideal amp for use in recording studios, for live performance, practice, and more.
