Some get bored with gear quicker than others. Hence GAS.
It's certainly not tainted with the same character between the channels, they're very different and then adjust them and they're different again.
Like I said earlier in the thread, varying the balance between the channel and master volume vs the power control massively changes the sound and that's even staying on just one channel so between all 4 there's a lot of variations to play with and find new sounds.
I also love the KT88 valves although I'm big enough to admit I don't know what impact they have on the actual sound, I just like the fact that in my head it makes the amp sound big. I don't know a great deal about amps or electronics but I know when I like the sound of a good amp and this is one to me.
Yes I like loud amps but the 200w aspect of it wasn't the only reason I bought it.
Plus with MIDI as well my multi FX can control the channel changes and in 4cm that just adds even more dimension and depth to it.
It's the best £500 I've spent in years, possibly ever.
I've got nothing but respect for Blackstar.
They also seem to be looking at what people want, rather than what they've chosen to put out.
Marshall have ignored the influence of the MK1 Guv'nor & compact multifunction amp heads. Surrendering Market share to JHS and H&K .

Seems to be showing losses of over 604K for 2016, and over 785K for 2015.
However someone with a feel for these things should read through the rest to get a better picture of the assets, how expenses are accounted for, etc. (The have a huge loss taken from the Gross Profit for "Administrative expenses" for example, I have no idea what that would be.)
Hey,Danny 1969 "a few bands of 60 year olds gigging cheese from the 70's in pubs" ,
What's up with that?
some sniff at non valve
some sniff at midi
some sniff at covers
can you imagine how boring this forum would be if we all agreed?
The only 2 times I've seen BS amps on stage was Steve Craddock and the band that supported BSC in 2016. Other than that I've not heard their higher end amps.
As far as their practice amps go I'd be hard pushed to buy another one. Their HT range is a hybrid, is it not? One pre amp valve and a transistor power section? They're not full valve and in that case I'd prefer the THR. Having said that... I'll take a Marshall any day of the week

Not really, they are almost full valve in both the pre and power amp but in the preamp there are some Solid State gain stages.
The stages which are valve are the ones that give a valve amp most of its 'valve' character, but the bulk of the signal path is solid state - it's closer to a solid-state amp with valve stages than a valve amp with solid-state stages. That's not a judgement on the sounds quality or anything, simply what it is from a circuit topology point of view.
Taking the HT-5 for example:
IC stage 1 > IC stage 2 > valve stage 1 > valve stage 2 > IC stage 3 > IC stage 4 > IC stage 5 > IC stage 6 > phase inverter (discrete transistor) > output valves
7 solid-state stages vs 3 valve ones.
Most of the distortion occurs in valve stage 2, and the dynamic control of the speaker is from the valve output stage.

The other much cheaper way of building a hybrid amp is to use a valve preamplifier and a solid-state power amplifier .... This is what Marshall do in the valvestate series .... It's much cheaper to do as there are no expensive power valves no expensive output transformer .
I kind of see the Blackstar HT series as being a clean boost pedal in a valve amp which to be fair is what many many people do ... Stick a clean boost in front of a valve amp
Overall Blackstar makes money, just about, on some level, according to the sheet. They are paying off investors goodwill and paying a lot of directors and salaries. I'm no accountant but it looks like a decent enough balance sheet as long as they have a plan to turn the loss positive over the next few years.
With the overall loss though you can understand the focus on the volume products, they are not going to overturn a 600k loss selling 50 boutique amps a year, they might selling 50,000 Core amps!
(For what it's worth I wouldn't describe the power amplifier section as all-valve either since the phase inverter is solid state and is usually considered part of the power amp.)
The way the distortion is generated is actually exactly like using a Tube Screamer set as a nearly-clean boost into a valve amp - the 'TS diode clipping circuit' in the Blackstar doesn't start to clip until the valve is already well overdriven, and the sound of it is then entirely masked by the valve distortion. The next IC stages operate the tone stack, the FX loop and the master volume control - which is equivalent to using an EQ pedal and a clean boost in the FX loop of a valve amp - the phase inverter is a clean transistor stage which doesn't add to the distortion, and the valve output stage is exactly that…
So in many ways it's pretty much a sort of 'conventional signal path' in the way a lot of valve-amp users do it, but all in one box… guitar > TS > valve preamp > FX send > EQ > boost > FX return > valve power amp > speaker.

"the phase inverter is a clean transistor stage which doesn't add to the distortion" A high voltage, MOSFETransistor in fact IC.
The stage also has a constant current circuit in the 'tail' and is capable of very high levels of drive at low distortion, a low source resistance * compared to valve PI and extremely well balanced drive. Now, all those qualities are anathema to 'seat of the pants' gitamp design where things are left 'to do their thang!" but is fundamental to the Blackstar creed. They want circuits to do what THEY want them to in the WAY they want them to, WHERE they want them to do it. So yes, ICs develop modest amounts of gain, enough so that when passed onto (noisy, miccy, expensive!) valves the BAD part of the valve is overcome and just the (controlled) distortion produced.
Now if this sounds a bit 'sterile' and contrived ok, it might be but the design approach means a good amplifier can be produced at reasonable cost and moreover the 'scientific' approach means very good consistency time after time . Ok, a few folks say "consistently bad" for them, but as I have said 'you can't please....'
*The big amps use an ECC82 as an extra PI driver to get a really low drive Z and that allows lower than usual grid leaks on the OPV grids which helps with modern valves, many of which have excess grid current and having low resistances about helps mitigate collateral damage when (not if! ) a valve dies in a spectacular manner.
I am also sorry someone had reliability problems. I can assure everyone that amplifiers were VERY rigorously tested and reliability is another plank in Bs philosophy.

Wow as much as that is SS? I think I was maybe overcompensating and trying to be too fair, I usually say (on ultimate guitar, when it comes up, which is about once a week) that it's about 50:50. I guess I should look at the schematic again.
(a) I'm not sure I agree. If that's true then there's no point in high gain valve amps.
(b) Yeah. They're a lot more valve than those type of things.
(c) I don't really agree, either- I can mix and match boost pedals with a genuinely all-valve amp, I can also turn them off to see how the amp sounds when it's all-valve, and a boost pedal doesn't turn the phase inverter solid state, etc. etc..
Yeah. As I said above, we get about one thread a week on UG asking about them, and it's clear most prospective buyers still think they're all-valve.
And I think the pedals still say "pure valve" on them. (what's "pure valve delay"? )

Well when you do Dave, work out how much GAIN the ICs contribute compared to the VALVE stages.
You only need a bit of gain to get the signals above noise and at a low impedance which helps keep noise low further along the circuitry.
Dave.
Interestingly I like some (but not all) purely solid-state amps - like old Peaveys - exactly because they have a much more open, less controlled sound and response. If that means they get a bit 'ratty' and 'harsh' when pushed hard that fine by me - but I understand that's why a lot of people don't like them!
