Gallien Kruger MB500 head 350w @ 8Ω, 500w @4Ω 3.4 lbs Loud and proud! This is one of the best amps I've ever had. If you're a GK fan, then you know the score. These hit hard and are super portable. Frankly, if I didn't have the MB Fusion 800, I'd rock this amp full time. And I honestly did try...

The legendary GK MB500 with a never used footswitch and never used footswitch cable. Power cable included of course. No longer in production. Have you used one of these? Conservative power ratings mean serious volume. I never needed more power than this provided into a 4 ohm cab from...

GK MB500 bass amp head with power cord. Excellent working condition. Has a small superficial scratch on the top. Crafted in USA. $335 shipped PPFF

For sale is a GK MB500. Includes power cable, unfortunately no pedal. Some light scuffs and scratches on the top from normal use, and the master volume can be a little scratchy if you haven’t used it for a few days; rotating the knob back and fourth a few times clears this up within 10 seconds...

Hi there, LOCAL SF BAY AREA SALE ONLY I’ve got a nice Gallien-Krueger 1001RBii for sale. Works great no problems. Includes skb road case and power cable (not pictured).

This amp head is in great condition, it does have one flaw the mute switch doesn't function properly. This is the reason for the low price. Everything else functions as it should and it will come with a footswitch and power cord. Price includes shipping in the Conus.

This head is new in the box and only taken out to take pictures. The price is firm and only interested in a GK mb500, Magellan 350, or a Tonehammer 350 or 500. These are the only trades I am interested in but cash is king! Pm me with any offers or questions thanks.

This head is in excellent condition and comes with gigbag and power cord. Please pm any offers or questions. Thanks

I brought this head here on talkbass and it's in excellent condition but more than my needs. It comes with the Mesa gigbag and power cord. The only trades I am interested in are GK mb500 or mb800 heads plus cash on your end. Cash is king and if local I can work out a in person deal.

GK MB500. Good working condition. Originally bought it here on TB: SOLD - GK MB500 I purchased this for a backup head. Used it on a 4 hour gig 2 weeks ago and it worked great! Includes power cable. $265 shipped USA conus

This head is in great working condition and only selling to fund a combo amp. It has its fair share of topical scratches (reason for the lowered price). I can add cash for the right combo but cash is king! Features 500W @ 4 ohms, 350W @ 8 ohms Digital power amp 4-band active EQ with contour...

Gallien-Krueger MB500. I bought this amp a few months back. Played several outside gigs with it. Sounds great, dependable, no issues. There are surface blemishes on top and bottom. Amp works as it should. Only selling to try out more gear. Includes power cord. $340 shipped PayPal USA conus

Great amp that has never let me down at a gig. However, I found myself with an Arkham Oracle and a Quilter Bass Block, and I already have a backup. This l'il guy is 500W of power and ridiculously light. 500W @ 4 ohms, 350W @ 8 ohms 4-band Active EQ GK Contour Control Footswitchable Boost...

GK MB500 micro bass amp. I am the second owner of this little powerhouse and it has only been used as a backup amp in case my tube amp ran into any issues. It has some scratches on the top from the previous owner, but it works flawlessly and sounds incredible. Foot switch included. Free US...
