Krank - I get why amp tech’s groan a bit at some of the PCB layout choices, but I think most issues people have are from either using a shit cab or not dialling them in right. I think the Revolution Series 1 and Krankenstein are excellent sounding amps and a cool and valid take on a modded Marshall. By all accounts Tony Krank was a bit of a divisive character and their business probably existed in a bad transitional moment for a company like theirs (who might have actually stood a better chance at surviving in the current social media climate).
Jet City get kind of sneered at a bit too, can understand why (because it’s always going to get compared to a legit Soldano), but I’d pick it tonally over a lot of my other nicer built amps. Or even over a lot of the trendier stuff you see these days like (say) Victory or Dover or whatever that cost a lot more.
