I purchased the smallbox combo used and it had the h75 and i felt like the top end was a bit harsh as well in that setup. The creamback 65 is the speaker for that setup. I realized it may not be perfect because it's a 1x12 open back combo.
I really like the tone I get from this small combat format. It´s unbeliavable! Of course it should work better with a closed back 4x12, but for me having this kind of portability with a great tone it´s ideal!
We are always searching for the perfect tone and this quest never ends because we don´t know exactly what we really want. Maybe I should just practice more, cause I believe it´s not the amp´s fault
