I am needing a new combo amp that is suitable for playing in church. I am wanting something light but loud enough for the size room that we will be playing. I have narrowed it down to a Carvin MB15 or the TC Electronics BG250. Both are in the price range that I want, have the volume that I want , and about the weight that I want. I don't use effects much for anything but playing around with(this will also become my practice amp at home replacing my Rumble 15). JUst looking for some point of views on either amp.
