Both in very good to excellent condition. Only 6 months old, but both have been gigged. The amp is amazing and does everything you could ever want. Of all the manufacturers who have tried to come up with the "Everything to everyone" amp this is the first true success I have seen. For whatever reason, the new XB3 line hasn't really started distribution here in the US, but after trying both it and the UB series I chose the XB3, as I felt it sounded a little more traditional than the UB line and a little louder in the Lo-bass region. This is the second loudest 410 I have ever owned, with the Bergantino HS410 being the loudest and that only by a nose. Amazing cabinet. The STLMX comes with all necessary cables, and factory 5-button FS. Say $625? The XB3 comes in original box with casters and original warranty. Say $500? Make me an offer for both and I'll cutcherz a deal deal!! I have to move this to make room for the touring rig, as Im leaving for 6 months in October. I may entertain the following and ONLY the following in trade: - Ampeg SVP-Pro preamp - Sansamp RBI or RPM - Ampeg 810 fridge (local meet only, and only certain years) - GB XB3 810 - Feel free to run any large format cabinet by me. pics avail for interested parties. DO IT.
