Hi folks, I'm ready to pull the trigger on a new pair of speakers and I'm hoping people with direct experience playing through the two G12H versions I listed in the thread title (not the 55Hz) can chime in with their opinions/descriptions on the differences between the two. The 70th Anniversary model is probably my all time favorite guitar speaker, so I'm curious if springing for the Heritage version will leave me feeling it was money well spent, or just disappointed. My concerns stem from past experience with really liking the run-of-the-mill G12M 25 watt Greenbacks, but being completely disappointed after buying the Heritage G12M 20 watt Greenback speakers. FWIW, Avatar is running a good sale on brand new Celestions right now. Thanks in advance for sharing your knowledge and any guidance or advice.
