GK Neo 115-III for $450 or GK 115MB for $250.
The Neo is 400 watts and has neo speakers while the MB don't have neo speakers and only 200 watts. Is the Neo worth the extra $200?
Yes, the Neo 115 would be worth the extra money. I had the 115MB and it's not bad, but if you ave a decent amp the Neo cab would be a better setup. If you have the spare money that's what I would do.
