Hello Talkbass, Background, I have been playing bass for about a dozen years (I said I played, I didn't say I played well) and it has come time for a new amp. I am not looking for the moon, this will mostly be something for me to play by myself, but I would like a quality piece of equipment that could handle playing with others and possibly more, so I have it narrowed to the TC Electronic BG250 and the GK MB115. That leads me to my question. I am not asking about which sounds better, that I can handle. However, the GK Mark 2 series will offer the Powered Cabinets which TC Electronic will not have. Is there an advantage/disadvantage to an MBP setup vs buying two identical combos and using an A/B/Y switch (ie the Morely Quad Box) to use both combos at the same time. I would love to know if anyone has had experience with using either setup, and how you liked it in the end. Thanks all.
