Hidey ho my compadres, today I received my new amp from Sweetwater and I quickly gave it a workout. The reason the title has question marks in it is because I'm not really sure if this is more of a review of the GK or of my other bass amp - the diminutive, lowly, discontinued Hartke B600, 60 watt, one 12" speaker combo. For the longest time I have been impressed with the little Hartke. Mind you, I've been around the block with amps a few times - Carvin 1000 watt stack, vintage Ampeg 100 watt tube head on I forgot what cabinet, Mesa Walkabout Scout and a bunch of other things I just can't conjure up right now. I bought the little Hartke on a whim years back and have been constantly impressed by it's sound, volume and range of tones - all for around 300 bucks. Anyway, back to the GK. I did a lot of net surfing to decide on a new amp (GAS, no other reason really) and finally decided to give the GK MB112 a whirl. I gotta say it's definitely a nice amp but I'll tell ya - the Hartke musta had me spoiled. I think the Hartke sounds as good if not better! Again, not the say the GK doesn't sound good - it does, but that little Hartke!! Back to the GK - I will say it has PLENTY of volume and handles a low B string effortlessly (the Hartke breaks up at half volume with the low B). It is also significantly LIGHTER than the Hartke. So you have more volume, less weight - a good thing for an older guy with 22 titanium parts in his back. On the other hand the Hartke has a tilt back feature which is very nice when using it as a stage monitor. But back again on the other hand the GK has an XLR line out where the Hartke has a regular guitar cord type of line out. All in all if you're looking for a very nice amp I would suggest at least checking out the GK. In my case, I'm not sure if it's really money well spent yet. I'll fiddle around with it for a few more days before making a decision to keep it or return it. That's my story and I'm sticking to it! White Funk - OUT!!!!
