    I had a good chat with the engineer this morning about these. My band is endoresed by Blackstar so I'll be getting a 500w Combo + 250w Powered Cab in June when they first drop in the UK. To be honest I'm really excited, but a little nervous as I'm going to be moving on my Barefaced gear 

    poor you!

     

    as an amp tech i see quite a few blackstar amps, they tend to just have valve issues though, so not end of the world.

    personally dont like the sound of them though as they tend to be really fizzly

    Interesting. That solves one potential issue. The other issue with the V6 is that it runs on 2 ohm and 4 ohm tap only. I have read things that it is safe to run it with an 8 ohm cab, however that goes against everything I have read about valve amps. There is very little info to be had on the V6, other than they are big heavy and loud!

    impedance mismatches get more and more dangerous as you get to higher voltages.

    I personally think that a 400 watt valve amp is beyond overkill. So much fun though. I played a gig with a VBA and it was just ridiculously powerful. I ended up buying a Trace Elliot V6 years later. I'm not sure if it actually 'is' 400 watts, but it is really loud and has loads of clean headroom. You have run it at silly levels to get any kind of grit. It is not that kind of amp.

    they do about 220watts if you leave the ecc83 in as the phase splitter, if you swap it out for an 81 they hit around 300. v6 that is.

     

    I really want another v6

    My 4xKT88 MJW is 253w clean and 544w fully clipped. If you multiply that by 1.5 for 6xKT88 (not strictly accurate or scientific but a guide nonetheless) you get 375+ clean and 800+ fully clipped. It would be interesting to know what the big 8xKT88 amps are on the scope. If anyone wants to come and measure my Laney, please let me know. :crigon_04:

    I'd love to put it on the scope to check that as those numbers seem a bit over the top without running the valves really hot or running original gec valves.

     

    I've got a 400watter I made but It was to heavy and impractical

  5. the tone control is a blend between a high pass and a lowpass as you go past twelve it cuts lows and vica versa. at 12 o clock theres normally a mid cut to compensate for the mid heaviness of the circuit.

    best way to use one of theses for bass is with a clean blend.

  6. Up for sale is my squire bass VI it's in great nick and barely played. It's fully stock and plays okay but could do with a few minor tweaks. I.e the truss rod needs about half a turn tighter. the nut needs the slots taking down slightly and the bridge action could go down a little. I could do this for a charge though.

    edit; these are just me being picky and i like to be honest in my listings.

    sounds great and does all the bass VI things though. I would prefer collection as I haven't got a case to ship it in.

     

    I would accept trades for it, a long the lines of vintage pedals / amps and studio gear or other interesting things in broken or working condition.

    I keep seeing posts about the concerns with speaker cab ohms ratings, and although with more efficient speakers and higher powered amps this is mainly irrelevant these days it got me thinking.
    With the old valve amps I believe you could plug a dummy resister in to simulate having a speaker plugged in so as not to damage the amp if powering up with no cab connected. Could a variable resister to used in cabs to allow you to alter the ohms rating of a cab, allowing for greater versatility and mixing and optimal matching of cabs?
    Like I say, probably redundant these days with the more efficient equipment easily available but I was just wondering.
    Waddya think :)

    thats why they have different impedance taps

  8. with valve amps you can go lower but not higher, but having an impedance mismatch will mean less power. At those sorts of wattages though it's not that massive difference. So running it into 4ohm will be fine.

    As to speakers you'll want the most cone area possible to get maximum sensitivity. Great amps though and use some cool valves
