I was planning on adding a MBP115 to my MBP112 and Plex pre amp. However, they seem to be very few available. I was hoping to find a used one but after checking the TB classifieds, CL, evil bay, and Reverb I haven’t found a single one. I checked with the largest chain in Canada, L&M, and they have no stock and would have to order direct from GK. Are these cabinets becoming obsolete? I’m also concerned with being able to sell it if I’m not satisfied. I already own a MB115 and wanted to simplify my set up by bypassing the pre in my combo.
