OK, I just came from the rehearsal studio and wanted to post this while it's fresh in my mind. I can sum up my first impression of this combo in just one word:
HOLY MOTHER OF PEARL WHERE HAVE YOU BEEN ALL MY LIFE?!!!
(alright, I was wrong about the one word)
I'll break it down now and try to be more coherent. I haven't done many reviews so I'll pretend to be one of you techy TB guys who knows what's he's doing
First of all, when I arrived at the studio the sidewalk in front of the building was completely ripped up and undergoing construction for the entire length of the block. I always park right in front and walk in so I hadn't brought along a cart. Now I had to park a block away and carry my bass AND the combo.
And I did! The fact that you can actually do that with this rig is amazing to me.
I set up the controls exactly as the GK manual advised: all EQ and Boost at 12 o'clock, contour and horn off, limiter on, master volume at 3 o'clock, then plugged in my trusty Jazz bass and rolled up the gain.
I got the gain to about 9 o'clock and it was loud. I kept going to about 10 o'clock and it was painfully loud, had to stop. The tone was deep, smooth and punchy.
I know lots of guys run their EQ basically flat, but I always seem to like mine closer to 2 o'clock (I'm like Edward G. Robinson...I always want MORE!). I turned all 4 eq knobs to 2 o'clock and began playing, and it felt a little like being in the subway and standing too close to the train rushing by. With both pickups on full and tone rolled up full the amp just had TONS of low end, chest thumping mids, and a clear round top end. I would say the tone was hi-fi, but definitely growly and aggressive. I don't really know how to describe it accurately, but everything I wanted was there.
BTW, I had to roll back the gain to 9 o'clock at this EQ setting, it was just too forceful to be in the same room with!
I played around with various combinations of EQ and pickup blends, and I couldn't get a tone I didn't like. Playing fingerstyle, favoring the bridge pickup and boosting the mids just a tad gave me the Jaco-on-steroids burpy thing, just stupid funky.
Rolling to the front pickup, using a pick, and engaging the Contour button was way cool too...deep boom with a nice click to it, somewhat JC Tool-ish.
The EQ on this amp seems to be really musical, everything is smooth and controllable, nothing ugly. I tried the horn, which many folks have noted is harsh. It seemed usable to me. I didn't really hear "harsh" but there is so much treble on tap already I don't see where I would ever need it (and I use a lot more high end than most players I know)
I don't know how, but GK seems to have disobeyed several laws of physics with this amp:
- It's about the same size as my 210 neo cab, but it's orders of magnitude louder.
- It's a fraction of the size of the 810 cabs I have owned, but it has a similar low end push and punch to the feel.
- It has (2) 12's and 500 watts, but it weighs the same as my Ampeg BA112 which has ONE 12" speaker and 50 watts.
I'll let someone with engineering expertise explain it all, but I am really impressed with this combo and I can't wait to gig it next week.
