The Killer Head....

Just purchased this GK Bass Head...,1001 RB ll...can't wait to get it home. "To be continued "
Music background: Been doing the music thing for over fifty five years plus.

Buy it!!!!

I've played with just about every brand of bass head you can think of. I've owned a Eden, Ampeg, and Hartke and I have to say this is the best amp head I've ever played great bottom I can't think of one bad thing to say. #GK4LIFE

This head is a MONSTER!

I picked up the 1001 RB-ll in December of 2015 as a xmas gift to myself :P I originally had the Ampeg SVT 3 PRO head, which was completely fine at doing its job, but I have always been curious about GK and started to dive into some research behind these heads. MAN I am glad I did. This monster packs a serious punch of over 700 watts, has a ton of room to find your preferred tone, and is solid state!!! When I first got into music, I thought it was tube amps or bust... which I quickly learned (mostly because I am a broke musician looking for the cheapest option) that was not true. This head proves it, and I can honestly never see myself buying another tube amp again. And for those scared about losing that tube tone, I also run this head with a Sans Amp GT2 tube amp emulator pedal which just brings the whole picture together.If you are looking for a reliable, powerful, and affordable bass head, buy this. You will not regret it.

it's THE sound

Absolutely love this amp!! Compared to Markbass and Ampeg, the GK, hands down, was the best. It has a unique sound. It's very versatile as well. It can be growly or clean or whatever you please. The EQ is easy to dial in all the way across the board. The DI sounds amazing through a mixer and makes recording insanely easy. Just plugged it in and used my amps eq. Didn't have to adjust anything on the pc but the volume. I am a die hard GK owner. I play metal all the way to jazz/fusion to electronic. I have the neo 212 and an Ibanez 405qm. Best combo in my opinion. But I'm sure you won't be disappointed either!

exactly what I needed

I did a lot of research on amplifiers put out by the big names (markbass, eden, tc electronic, ampeg) and all companies were nice. I needed the versatility of being able to play anything from gospel to metal and I found that and more. While trying out different amplifiers I would look at which one paired well with various cabs. After hours of testing out cabs my top two were the eden and my gallien kruger amp. BUT... the factor that sent me to the gk side was the two twelve cabs ability to bi-amp. This high end crispness sent me over the edge... it was exactly the tone I heard in my head and I couldn't be happier. I have never had any electrical issues and I just keep turning it up and it keeps putting out power. The only down side to this amp is that it's kind of heavy... that didn't bother me in the least so I bought it. Although it is overkill im going to end up buying the 115 neo because... well who doesn't want a well rounded bottom on a bass. Great job gk. Great job Sweetwater... till next time...
