Re: Blackstar amps.
I owned an HT100 and beat it but it worked great no matter what. It sounded really, really good. It was very versatile and had a great master volume to tame the 100w for home use. The cleans weren't boutique quality, but very useable and sounds great with a touch of delay or reverb.
Then I bought a Series One 100 and boy was I satisfied. I used to wonder how much better they could be than the HT stuff, but man it's a totally different sound and feel. The HT stuff are pure tube amps no doubt; however, all of the qualities you look for in boutique tube amps are present in the Series One and Artisan stuff. I absolutely love the Series One head. It has an interesting power scaling feature that doesn't just make it operate at lower wattages, it does something with the valves that makes them put out like the amp is on 10 but at low volume.
What sets the Series One stuff apart from the HT stuff besides the tone and all, is the feel. The HT to me felt a little stiff or dry or something like that. It would be analogous to walking on a dish sponge vs walking on memory foam. The S1 has a great natural feel with a little tube sag. I could make a great comparison with the 101b, but you would have to be very familiar with the 101b to understand it. Basically, the 101b has a very special feel which I can only describe as punchy. Even when you're playing legato, the 101b responds and sounds almost as if the notes are picked. It's precise and unforgiving yet liquid and responsive. Now compare that to the Series One and, basically, the Series One has a saggier more classic feel but still sounds nearly as punchy as the 101b.
The punchiness and feel is important to me. I've recorded some stuff with it and felt like I didn't quite catch some of the notes the way I wanted, but when I go back and listen to the recording, the notes have enough punch to still sound like I caught them right. I don't know if that makes sense to anyone else but me. All I can say is that feel and response is nearly as important to me as tone, and the Series One stuff has it.
They're pricy, but really worth the money. The only complaint I have about them is that the tolex scratches, dents and gouges easily. It's kind of a soft matte tolex that seems almost organic the way that it picks up scars and abrasions. Other than that I have no complaints at all. The FX loop is great and works with all of my pedals and FX processors. If you want something more classic, the Artisan stuff is awesome. They got the Class A stuff going in the Artisan line, and those amps start making magic when you turn up the volume knob.
As a guitar player , do yourself a favor and play a Fender Twin Reverb. All guitarist of all styles should at least hear what they sound like crystal clear. Fender Twins are IMO and many others the cleanest amps ever made. It's a pure treat to play through one. Another good value of a Twin is you can really hear differences between different guitars.
Thank you for the comments.
I agree that most people can build their reference to clean tones on Fender amps. I have a Blues Junior that has great cleans, but not even as good as the legendary Fender stuff. I have had it sitting next to some very high end amps and it made some of those amps sound like they had a mediocre clean channel. Fenders are more accessible than boutique stuff like Matchless. However, if someone can get their hands on a Matchless then they will know what those boutique enthusiasts mean by terms like shimmering, blossom, 3 dimensional, etc...
