Since using a dual amp config in the '90s I will pretty much always use two tube amps at once. One set richer and dirtier, the other cleaner and brighter. It just gives me everything I need. I'm lucky have at my disposal loads of top vintage and new tube amps accumulated over the years from the '70s on. I use attenuators so I can get the breakup I want at the volume that's right for the occasion. It's heaven! I don’t gig much and 90% of my playing is rehearsing or at by home studio. I'm still fit and I can lug the heavy amps around when I need and I think it is worth it even when packing away! So, why have a I just bought a used Yamaha THR100HD? I want to see how close it gets. And, if it gets close enough for me in most situations, I can change my amp situation which is not sustainable really. In 5 years' time I have to downsize my property to help fund my planned retirement. Those amps are taking up a LOT of room and, I expect, with a smaller property I won’t be able to keep them all. I can wall hang guitars, but not amps! As you know the THR100HD is a 100-watt (or 50 watts at 4 ohms) digital amp head with two separate amps. Each separate has 5 different amp types (SS, clean, crunch, lead, and modern) and then five different tube types (6V6, EL84, KT88, 6L6GC, and EL34) it covers every amp I've ever owned or ever wanted to own! My needs are pretty simple since I'm a classic amp guy. I don’t need to store tones, pre-sets need to be changed for different rooms and volumes anyway, I don’t need multi effects; I just want to replicate a handful of my classic amp settings to get my sounds. I like it's simplicity. And I love my little THR10. IF it can get very close to the FEEL and tone of playing my favourite amp combinations such as a Marshall MV50 with a cranked DRRi and a cranked VoxAC30 with a 5e3… etc.,… then I will take some amp decisions I already own two separate 2X12 extension cabs with vintage '70s Celestions that I rarely use, so I'd simply use them. I'll A/B each against the actual amp and see where it goes. I'll likely update this thread as I go, amp by amp. My kids don’t want my amps - they don’t play guitar so…. I've a strong feeling I'm going to be weeping as my vintage and classic amps get sold, one by one. Can I tear myself away from my classic amps? Dunno.
