I just purchase the MB115-II 1X15 combo

I order this amp just a few days ago, and man Sweetwater got it to me fast. I have been jamming on for 3 or 4 days with friends a little jazz and blues band we have. It covers medium venues very well I used it in a church of a little over maybe 150 people this morning friends Church worked great, with a keyboard player guitarist and drummer, and 3 vocals. 200 watts still had some to spare the 15in speaker can put it out there. Its is very easy for me to dial in the sound I wanted, I fell in love with the rich low end this amp can put out it very lush. I am very happy and I want to thank Ben and the guys at Sweetwater for all the help I know I must of drove them crazy asking and bugging them, but they helped me get the sound I wanted. Wonderful job guys and thank you all very much and now you know why I only buy from Sweetwater. That is the bass I play on my new GK MB115, that I also got from Sweetwater. Man Sweetwater they are just awesome.

POWERFUL

I ordered this to play at our church. I wasn't sure what to get, but since it's a large sanctuary (approx. 120' x 80') with lots of soft surfaces, I picked this one. Unboxed it, plugged my bass into it, turned the volume knob up halfway, and when I plucked a string I knew that I had bought way more amp than I needed (or will ever need). I had to turn the volume down to 2 to get the sound at a reasonable level. I returned it for a smaller bass amp. If you need a TON of volume, this one is a candidate.

GK MB115-II

Really fat sounding, versatile amp, with a ton of headroom. Bought a demo amp, there was an issue, and Sweetwater sent me a new one, hassle free. I couldn't be happier with this product, or with Sweetwater's customer service. Thanks Clint Bransteter. and everyone else at Sweetwater.

This is a great amp.

I purchase this amp and got it yesterday maybe around 10 o'clock morning, I called a couple of friends and we went to the Church and tried it out. Man we jam about 6 hours and didn't even know it we were having fun. This morning around 7:30 I got up and made some coffee my wife was gone to some ladies thing at church so I put some backing tracks on and played with the amp again. Both times I used the amp I used my Lakland 3TBS Hollowbody bass I got from Sweetwater and my old Ibanez Jazz bass I have had for years don't know where I got it. Well back to the GK MB115-II I must have drove Ben there at Sweetwater crazy I tried one amp out with a 12 180 watts just didn't have that shine for me. I had a MarkBass Jeff Berlin 151p combo I bought in 2008 before I heard of Sweetwater I played when I was playing gigs all over Texas at 69 years old I got tired and quit , Church is where I want to play been playing worship almost 40 years now, the Churches amp after 14 years I have been playing quit been worked on 4 time couldn't be fixed know more. So I donated the Markbass combo to them I was tired of it anyway to my ears they are a little one sound you know just not for me anymore . So went on my search like I said and man poor Ben I bugged him to death I guess and finally he asked one of his bass people, and you must remember they are all all musicians themselves and very awesome musicians, I would have saved a lot of time and Ben's time if I would have shut up and and asked and listen , the GK MB115-II 1x15 is awesome sounding very rich low end the 200 watts will get you heard, I like it a lot better then the Markbass Jeff Berlin 151p. But do yourself a favor don't be afraid to ask these a question they really know their stuff it will save you a lot of time and frustration. Sweetwater they rock

Great sound!

Got this for my son. He has been using a Fender Rumble 60 at high school. Now that he has graduated, he needs his own gear. Recommended by Norm Stockton. The sound is super clear, with great tone compared to the Rumble. It's also lighter and just a little smaller. Looking forward to hearing him gig with this amp!
