Product Description

A Pure Tube 20-Watt Head with Incredible Tone!
The HT Studio 20 amp head offers huge versatility for home, rehearsal or studio use and can be used with a variety of cabinets including the matching HT112 and HT212. The carefully voiced preamp coupled with a cathode-biased EL34 power amp, provides the user with the ability to create wonderfully lush valve tones. From pure boutique cleans, to mild overdrive that cleans up by backing off the guitar volume control, up to highly saturated distortion, this amp does it all.

  • 2xECC83 preamp and 2xEL34 power tubes
  • Two footswitchable channels

Overall Rating
Not what I was Looking For
Your general opinion of this product.
An indulgent practice amp. I really was thinking a low watt (under 15 watts)compact practice amp. However all the amps I found came up short in one way or another. Then my brother recommended the Blackstar. The guitarist in his band was really happy with the HT40. I notice a lot of people are wondering if the HT20 is loud probably is for most intimate settings however I think the "Studio" designation hints at its purpose. I thot the digital Reverb was pretty good on its on However the amp, Sounds Great with the Way Huge Aqua Puss in the effects loop. PeaCE
