Re: 1x12 80 watt Celestion Classic Lead 80
I have a G12H80 in my 1x12 18 Watter combo. The H80 is really similar to the Classic Lead 80 (it was built special for a boutique amp manufacturer, and differs only slightly in frequency response).
Anyway, I love it. I recently A/B'd it against a G12H30 in a Bogner Duende combo (which has a cabinet almost identical in size to my "Marshall". With my amp, I actually preferred the H80 to the H30. I think the CL80 will be a bit clearer, nice clear highs, and probably more lows. Flatter response overall.
