GK MB Fusion


from Undisclosed

Comments about Gallien-Krueger MB Fusion 500W Tube Preamp Ultra Light Bass Amp Head:

Having used a multitude of bass heads over the past 40 plus years, and having to wait on this to come out for almost two years since its announcement , I can truly say it was worth the wait.
The warmth and punch of this mini is unreal, and compared to My 80 pound all tube Head, I prefer the unique GK sound, (very smooth, to very gutsy) and has all the control you could possibly need.
