I've just got a new TC rig, Rh750, 212 & 210 and have fallen in love straight out the box, got it from Mark too (top fella), it arrived on Wednesday and I spent 4 hours fiddling with eq and all the other functions (as you do) only to realise the "pre set" tone is absolutely spot on, don't find it at all boomy although I can imagine if you did wind the bottom end on past 12 o'clock then it possibly could run away with you, at last nights "debut" gig I rolled the bottom off to about 10.30 and it was sweet as a nut. My only small gripe would be the lack of rubber feet on the cabs, I know it's got this super tough none slip coating on but I don't much fancy standing them on the pavement while we loaded the van. Apart from that, love it
