Gallien Kreuger Official Club Part 7

Ok!I am sure I've read it somewhere,but I just can't find it(Google,talkbass search nothing!).Is it safe to use GK speacon with non GK head (non biampable)? I have TecAmp Puma 500 and a GK 212 NEO.My guess is that it is ok,because those two pins that are not there cannot send any signal?

[kai_ski]

Aye

This is probably generally true, but you should first at least verify that, IF the amp vendor is using a 4 conductor speakon, that they are NOT connecting those "unused" connections to anything. Again, most likely they are not, because they shouldn't want to create support nightmares by not being compatible with a very common cable type, but it should be verified first. It may even be stated in their manual what cables are ok to use.

Now, most cabinets should handle such cases, but maybe not... I would not spend time opening up all those cabinets and sort it out, maybe best to just use a non-biamp speakon to avoid issues.

Problem is, we're talking about a cabinet that DOES have connections on those pins (Neo212), so we need to make sure the non-GK head does not.

I see. Well, I would still not trust the design, cheaper to get another non-bi-amp Speakon cable than taking the amp for service. We are talking about the most powerful outlet the amps have, just after the main power stage....

That is always the safest bet. You are right.

[m bazz]

Thank you,I already have regular Speakon,but since it is couple years old just thought to use new GK one,no big deal.But the question is not 100% covered so that's why I asked.
I'll do it safe way anyhow

[GreaserMatt]

I've owned a bunch of older 400rb's, & currently own an '87 I think; great amps. You just can't kill these things... I bought my latest one for $100; something was wrong w/ the regular volume pot; I removed it from inside the amp, & now just use the master vol like a regular vol. Works great & loud as hell, LOL...

I think I saw a TecAmp club, Try asking there also

Don't know for sure about your amp but I have been using a four pin cable with my Genz Benz Shuttle head and GK 112 Neo cabinets. I have had no problems with them.

[Dredmahawkus]

someone help me dial in my mbfusion! my 2-12 came today....I thought it was 4 ohms its 8! does that mean I need another one?

anyway how do I get that moslty clear a little bit of fuzz tubey fullness? I am confused when I put the preamp on and switch over the channel b do the controls from channel A still do anything? this is my first real amp.
I have flats and 10% overwound lindys on my jazz bass....someone tell me what to do to get a 70s sound.

I think so far after playing this for an hour I like the volume all the way up and the gain barely up......the other way around it sounds way too distorted with these flats on here.....everything else if pretty much at 12 o clock. presence is off deep is on....its on channel b with the red light on.

can someone give me their settings they like so I can try it?

[Chef]

At 8 ohms, you can add a cab if you want to.
Correct; channel A does nothing when channel B is on. You can set them for different gain structures, and footswitch between them.

I prefer the B channel as well.
I tend to run the master high, and the input low as well.
I run treble down a bit, hi and low mid up a bit, and bass down a bit.

[ksandvik]

When I got my MBFusion it took an hour or so playing for the tubes to settle in... And yes, 8 ohm cabs is a wiser choice as you could add a second cab if you need to. You only get 300+W out from a single 8 ohm cab config but in many cases that's enough.

[Dredmahawkus]

yeah it sure is loud enough....my walls are literally vibrating. Now that I made this jazz bass so muddy sounding I think I need to buy another with actives and rounds on it to get all the tones!

you think its ok to leave the head on the cab or will it shake its guts out?

I saw that post earlier about the cabs not sitting right......mine was rocking a little too....then I turned it 20 degrees and it stopped...must be my floor....but it reminded me of that. they must be so straight that unless your floor is perfect flat it rocks a little.

I don't I've ever seen my MB500 bounce on top of the cab when playing live. But I put a knot on the cable going via the cab handle to the unit so I don't accidentally drag down the lightweight MBFusion amp via the cable moving.

[Chef]

No way any bass should sound muddy thru that head and cab?

Do you have the horn in the on position, the back of the cab, and the attenuator turned up to 50% or so?

[Dredmahawkus]

I have thick flatwound strings and 10% overwound passive lindy fralins.....even with my little ba-108 it totally changed the tone of the bass...its like flat and kinda muddy now. I kinda like it for some things....I was going to change back to rounds to get it brighter....but I want a MIA deluxe active/passive....so I might keep them on and have the option. these strings are so thick they are hard to play anything fast. I had the bass setup to them too.

the horn bi-amp is on and the dial is turned to -2db

[Chef]

With the MBFusion, you -do not- want biamp on.

With the MBFusion, biamp should be off; you should be running full range.
