Greetings! I play bass for my church and have been asked to recommend some new equipment for the church to purchase. I'm thinking lightweight combo amp because we occasionally travel to other churches and most don't have their own rig. The sanctuary is medium-sized (seats approximately 600) and I do not go through the house system. I play along with a drummer, a guitarist who also does not go through the house, and a pianist who does go through the house. Based on budget, I have narrowed my choices to these: 1. Gallien-Krueger MB210-ii. 500 watts through 2 10" woofers. Weighs only 33 lbs. $699.99. 2. Gallien-Krueger MB115-ii. 200 watts through a 15" woofer. Weighs only 35 lbs. $499.99 Both of the Gallien-Krueger models can be ordered through a variety of online retailers (Guitar Center, musiciansfriend, Sweetwater). 3. Carvin MB12. 250 watts through a 12" woofer and a 6.5" midrange. Weighs only 31 lbs. $399 direct from www.carvinguitars.com 4. Carvin MB15. 250 watts through a 15" woofer. Weighs only 33 lbs. $329 direct from www.carvinguitars.com I would appreciate any feedback, comments, recommendations. Thanks!
