Blackstar HTSTUDIO20C 20 Watt tube 1x12 in. Studio Combo

The HT Studio 20 combo is the big brother of their critically acclaimed HT-5 and offers huge versatility for home, rehearsal or studio use. The carefully voiced preamp coupled with a cathode-biased EL34 power amp, provides the user with the ability to create wonderfully lush valve tones through the 12" Celestion speaker.

The guitar amplifier has two channels available for selection, a Clean channel and an Overdrive channel. Using the Volume control while on the Clean channel you are able to deliver everything from a clean sound through to a crunch tone. Alternatively you can select the Overdrive channel and again using the Gain control, change from a clean sound on the edge of breakup right through to a distorted lead tone.

The ISF control works in conjunction with the Tone control. It allows you to choose the exact tone signature you prefer. Fully CCW is a more American characteristic with a tight bottom end and more aggressive middle, and fully CW is a British characteristic which is more ‘woody’ and less aggressive.

The Blackstar emulated output design is a new benchmark for pro direct recording. This no-compromise design makes it easy to get your tone to disk and tape. You can also use it to run a line out to a PA.

The reverb control sets the overall level of the reverb effect. With the control fully counter clockwise there will be no reverb. Turning the control clockwise will increase the amount of reverb.

The amp features an effects loop to allow you to connect effects pedals or other professional equipment using the return and send connections. The Effects Loop Level switch sets the effects loop to either +4dBV/-10dBV, which enables you to use it with either professional equipment (+4dBV setting), or with guitar level effects such as effects pedals (-10dBV setting).
