Headphone jack is switchable between headphone and direct out. Would assume you could use direct out for tuner.

GK MB 200: Part Two
- Thread starter Chef
- Start date
Since harder rock is kind of subjective hard to say. I play in an alt rock band and used it with a 1x12 and it was fine but we don't play super loud.
Is Powerhouse 4 or 8 ohms? Is it an efficient cab or does it typically need a lot of power to sound good? These are 100 or 200 watt amp depending on cab impedance. Not a huge amount of power for bass.

I'm running two cabs, both 4 ohms. One cab is my 412, the other is a 410 and 115 in the same cab (PH1200) I want to get two amps, run each to one cab with a Y cable for bass. Guitarist is using a 100 watt Marshall half stack with a 412 can but is hardly pushing his amp. I don't have the opportunity to try the amp out as nobody stocks them around here. I might buy one and give it a try, if it's not for me I'll sell it.
These are the cabs for reference
Well, I know Tom said "yes and yes", but honestly, I wouldn't use the attempted plug in to figure out if it's combo or not (your question #2). Just look at it. Here's a good picture of one. They are very clearly marked if they're combo. I'd strongly suggest just looking, and not plugging, to see. I'd be concerned about damaging contacts in a non-combo trying to insert a 1/4" in there (don't know for sure, but wouldn't want to find out the hard way... especially when there's no need).
Would be good to know from GK if there was a reason they switch from a combo to a speakon only jack. Hard to believe that cost was the issues since the price difference is small and likely even smaller in manufacturing quantities.
In any case, I ordered one of these:
Amazon.com: Neutrik NA4LJX Speakon to 1/4 Inch Female Adapter: Musical Instruments
My 2 primary cabs and 2 primary amps both have Speakon. However, sometimes I run across situations where the cab maybe in a shared space and 1/4 only. Small and cheap enough to keep in a gig bag.

Thanks, Vic. I bought it last night and haven't had a chance to really inspect it, let alone use it... so I'm going on little information, admittedly. I'll have a better look tonight. I appreciate your consideration and advice.
It had nothing to do with cost. It had to do with quality and minimizing risk of damage to the amp. See my earlier post.
I did which is why I was hoping to see something official from GK. Are there other class D amps out there with combo jacks and metal chassis?
I seem to recall hearing 1/4" jacks are no longer allowed for power amp use in the EU due to the shock hazard?
Ahhh. I did a quick search and found this link about building a Class D amp, with this quote in it... hopefully it's trustworthy enough for you.
"Class D designs don't ground the negative side of the speaker output. So they SHOULD NOT be connected together, nor should they go to ground."
Let's Build a Class D Amplifier!
I think there have been other Class D amps with the combo jacks, but maybe they weren't as worried if the actual voltage levels at max output weren't high enough to risk human injury, but my guess is, the combo jacks will disappear and/or be more strictly used for very low power applications... at least with Class D amps.
However, even then, I'd still think you could risk damage to the amp, and there's just no need. Combo cables are trivially easy to buy or even make from existing cables (or even the adapter like you got), and the Speakon connector is just so much better. Just makes sense to me to standardize on the non-combo, eliminate all risk, and call it a day.
I don't speak for GK, but I would be willing to bet you cash money cost was not a primary concern... maybe not even a concern at all.
IMHO/IME anyway.

Good news (for me): mine looks like this.
On the speaker jacks...
First, unless it's CLEARLY marked as a combo jack (which usually also means it's green), it's definitely not designed to accept a 1/4" plug, and don't try to put one in there. You could be damaging the Speakon contacts.
Secondly, these Class D amps are not like other amps. You don't have a negative that's the same as chassis ground, which means if you have a metal 1/4" plug housing, and something metal touched that and any exposed/unfinished metal on the amp casing, you could see sparks when the output is being driven.
Finally, Speakon connectors are far superior to 1/4", not expensive at all, and converting an existing 1/4" cable to 1/4"-Speakon (or even Speakon-Speakon) is simple... it doesn't even require soldering.
Bottom line - go Speakon and never look back. It's better.
Hi,
Obviously from the image, I did plug a 1/4" a few times before I caught on. Then I was worried that I may have damaged the connector. However, it works great with the Speakon connector.

Hey, anyone use one with an 8x10 cab yet? I used to run an Ampeg V4B (100 watts) into one and it was always plenty loud enough for anything 
.
.
I ran mine with an 8x10 several times for pickup gigs. My usual rig is kept in our sound mans gear truck. Through a big cab I ran off stage volume only, no PA, and never turned the MB200 up over half.
Not much headroom left, but it was VERY loud.

Been reading through this thread and the previous and I'm really leaning toward this amp (provided I can get a hiss free one..lol), but had a couple of questions
So, are these made in the US now?
I just got my first bass (A MIM P that's at the shop for a setup) and was planning on spending $200-$300 on a combo for practice/jamming, but now I'm thinking I'll grab one of these & play through headphones until I can afford a decent cab. Nobody will want to hear me practicing anyway...haha!
Do I need crazy bass headphones all the hip-hop kids run around with or will my old vintage 70s cans work? Don't want to break them as I use them for listening to my "hi-fi!"
Will 200-watts keep up with my buddies AC-30?
Why carrots and not tacos in all these polls I see? (It's tacos at another forum I frequent and tacos>carrots, IMO.)

So, if I order an MB200 today it should show up with "Made in the USA" on it? That would be cool.
When looking for a cab, should I be looking for the most efficient one? I'm going to run back through these threads & write down what everyone is using & then grab the prices.
