I want to get an old school valve/tube amp sound and the amps I'm looking at are the Fender Bassman 100T with a Rumble 4x10 or the Ashdown CTM100 with an ABM 4x10. Just wondering if anyone has experience with these amps live and how loud these Amps will go before you can call it distorted. I'm playing mostly small and medium venues. Is it worth getting a 100w tube amp? Will it have enough headroom for cleans? Or should I just get an ABM600 and save myself from the valve experience?
