    Comments about Blackstar Series One 104EL34 100W Tube Guitar Amp Head:

    Well this a great amp. The stock power tubes are awesome (TAD EL34B-STR)because gives a lot of head headroom, more chunky sound in comparison than a marshall JVM stock. I recommend to change immediately the preamp tubes for a new ones, I prefer TAD's or JJ's but it depends of what sound are you looking for or you do like.
    It is very well made! both outside as inside. No complaints about that.
    This is a fixed bias amp. It is too easy to do the bias because you don't have to take out the entire unit from the crate, if you see at the base it has four entries where you can measure and calibrate the millivotage passing through the power tubes. (100mV recommended)

    Clean channel is perfect, you will love it.
    Crunch channel is a little bit sissy, needs more balls in my opinion.
    OD1 channel sounds like an Marshall JCM800 or closer. It is the best channel in this amp but I think it needs more gain for a better rhythm distortion.
    OD2 channel has an much modern sound with more gain and basses.
    I use the OD1 for Solos and the OD2 for rhythm.

    This amp is loud as hell!!!

    What I don't like:
    1) Clean and Crunch channels share the EQ, so as the OD1 and OD2. It sucks!!
    2) The footswitch cable is unique, so if you break it you'll have to order it directly from Blackstar.
    3) When you are gigging and the lights are almost down it is hard to see the dot on the knobs to equalize or change the configuration of your amp.
    4) The weight is not evenly distributed in the amplifier, one side is much heavier than the other for the position of transformers
    5) No reverb

    Despite what I consider bad this would be a great acquisition.
    And Yes, I would recommend this to a friend!!!

    Blackstar rules!!!

    Great tone here!

    Comments about Blackstar Series One 104EL34 100W Tube Guitar Amp Head:

    I gave it 8's across the board. The Clean is one if the better on hi gain amps. It sounds great with single coils and humbuckers both. You can get some slight break up with the gain cranked too.

    The Crunch channel is probably my favorite on the amp. It stays focused and is great for classic rock and blues. It gets much more aggressive with the Super Crunch engaged but still stays focused and has tight bottom end. It's very Marshall-ish sounding but I'm talking older Marshall. Not the crap they put out today. It's sounds way better than the 410H.

    The OD1 seems to add a gain stage and is capable of sounding like the Super Crunch channel or more modern if desired. It doesnt stay quite as focused sounding as the Super Crunch though.

    The OD2 is pretty much the same thing with even more gain though if desired.

    Over all it's one of the best and most versatile high gain amps out there. I've owned Bogner, Splawn, Mesa, Marshall, VHT, Egnater, ect. and I'd definitely recommend it if you're looking for classic and modded Marshall tones with a great clean channel.
    Great features in this amp. It could be even better if the EQ section was independent for each channel. The ISF really helps to shape the tone.
    It seems like a pretty solid amp. I'm not too fond of buying amps made over seas but so far so good. It comes with TAD power tubes and a mixture of TAD and Sovtek preamp tubes. They need to go to a different style cable for the footswitch though. Maybe a midi cable or something easier to find. The one supplied would be a hard replacement in a pinch. The transformers are both mounted to one end of the chassis too making it lop-sided when carrying it.
    I'd say it's a pretty good bang for the buck. I've tried pretty much everything out there and it's comparable in price but it wins in the tone department.
