So it's time to upgrade from the combo. I have a GK MB115 right now that's in the process of getting repaired, and I intend to use it as a practice/spare amp when I get it back. I know, I know… "Do a search", "Tons of threads on this". etc… I'm going to get more specific in a second. I mostly play funk, rock, "jam band" and some electronic sorta stuff. I'm starting to play with bands more and am looking for something that will suffice in a larger bar-type venue, but with the ability to kick it up a notch if needed. After tone, affordability and reliability are my top deciding factors. First thoughts: GK MB500 w/ 1x15 Neo Cab - I do like the sound of my current GK amp and wouldn't mind keeping the tone. Ampeg PF500 w/ PF115HE Cab Very intrigued, but haven't played it yet. As mentioned, reliability is important. I'm hoping to buy used on the forum, so I don't want to have to worry about inheriting something sketchy that's out of warranty. Seems like no matter what the brand is, there are people on here who have had issues with it. What else would you recommend in addition to what's already listed? Is 500W enough? I figured I could always just get a second cab down the road for the larger gigs.
