Product description

Designed for electric guitar players, the Blackstar HT-20RMKII is a 20W tube combo for guitars. It sports two channels, one for Clean and one for Overdrive. An included footswitch allows you to easily switch between channels. The overdrive channel offers a three-knob tone stack and Blackstar's proprietary ISF tonal filter, while the clean section gives you a simple tone control. Reverb is also on hand for adding space to the signal. Each channel offers two different voicings for multiple timbres. With an ECC83 in the preamp stage and two EL84 power tubes, the amplifier offers the rich, harmonically complex sound of tubes. You get all the breakup characteristics of this amp at a much lower output level by pressing the output power reduction switch. This takes the output power down from 20W into 2W. The speaker is a 12" Celestion Seventy80.This combo amplifier offers a 1/4" line output and an XLR DI out. Both of these respond to a voicing switch that allows you to change the tonal characteristics of the emulated signal. Choose between a 4x12" closed-back or a 1x12" open-back cabinet sound. You'll also note an effects loop with switchable level. This enables you to use the amp with guitar-level effects such as stompboxes or rackmount gear. Onboard are 1/4" 16- and 8-Ohm speaker outputs, as well as a stereo MP3/line input and a USB port. UPC: 845644004997 In the Box Blackstar HT-20RMKII 20W Tube Combo Amplifier

    Hi. I have a Blackstar HT20 combo amp. Can I hook up a factory 16 ohm 1x12 Blackstar voiced "extension" speaker cabinet, along with the stock supplied 12" 16 ohm factory Blackstar voiced combo speaker (1 in each of the 2, 16 ohm output jacks in the back) along with (at the same time)...2-8 ohm celestion Vintage 30 speakers wired in SERIES in the 3rd 16 ohm rear output jack??? I'm wanting to run 4-12" speakers (2 blackstar's @16ohms and a seperate 2x12 cabinet (2- 8ohms speakers) wired in series). All at once. Will this load hurt this amp??? I hope this is not to confusing. I tried to be specific.
