I never thought of mine (very same cab) as dark. It’s fairly neutral if I had to label it. I also have the TC 112 (non-AF) like Charlie’s and they are similarly voiced, I’d say, though the 15 is def “bigger” in girth. I hope all your components are working. I’d bet Duke would be happy to help you if you need to troubleshoot it.Last week I consumated the deal for a TC115AF 4 ohm cab. It is a v1 with the 'mondo' horn. Not really sure what it is ... Overall the cab seems a lot darker than expected. Yes... I have flipped the switch and one position is darker than the other.
I haven't spent quality time with a TC before. Are these cabs darker than they look ?
