HP 10 "(very medium type)
clean channel and overdrive channel (footswitch sold)
3-band EQ + knob ISF
Effects loop with 2 output level
Headphone output with speaker emulation (1x12 or 4x12)
Amp very comprehensive for its category.
The configuration is simple, but be aware that the ISF knob acts greatly on the sound. He lets go of a sound American (type fender, mesa boogie) to a more british (type marshall, vox).
Having sold with a footswitch is very valuable.
I use a Fender Start mexiciane.
Clean channel: very good, provided you have a reverb to give the presence and magnitude to the sound. It is worth can not be clean of Fender, but he respects very much the sound of your guitar.
Channel overdrive: Great! The sounds are really superb, you can have a very light crunch or rather a big overdrive. One can easily get a sound close to AC / DC or Eric Clapton.
The dynamic is also excellent, even at low volume. It feels good heat lamps.
I play in the apartment with the volume on 2 / 10 and it's a real pleasure.
The ISF is the miracle, whatever the channel.
In addition, it excepts well stompboxes. I use a Line 6 M13, an EHX Holy Grail, a ds2 boss, ibanez and a wh 10 v2 and the sound is really stunning!
Blackstar hit a home run with this amp. The latter is intended for use apartment / house / home studio. The price may seem excessive, but it is by far the most comprehensive 5w tube amp. Having tested Grestch the fender vibro field and peavey royal 8, I can tell you that the Blackstar is over, there is no doubt about that.
