Many thanks, have consciously avoided an eq like that since my 1980s days of playing music on boogie boxes with graphic eq's😂😂.
Suppose I just have to forget ingrained notions from hi fi usage, i.e. running tone knobs flat or bypassed.
Have been trying the little thing through
1) A Laney N410 sounds very good tweeter at 1/2 setting. As usual I find this cab a delight and the little Amp sounds pretty hi-fi and goes too loud for home.
2) Laney N115 no tweeter
3) the Ashdown 410 that came with it, just old school.
4} Epifani UL212 which I correctly expected to be too hungry @ 4ohms for the Ashdown.
Still finding it's best through the old tungsten weight Trace 1818t so I will give your recomendation a go later and give my KSD 605 (audere pre and tapewounds) a run out. Will set pots flat and tweak the q switch till I get a starting point. We shall see how it goes. I need to do some displacement activity today, practice a better option than Nicotine & Coffee.
