I'm playing a 2012 Marshall JMP-1C 50th Anniversary through a 1x12 with a 1963 Jensen C12Q and another 1x12 with a 1967 Celestion G12H25 75Hz T1217 Greenback and the tone is completely amazing! I'm using 4 guitars:
1. 2008 Gibson Les Paul R9 Standard
2. 2021 Fender Custom Shop Telecaster 60 Relic
3. 1978 Fender Telecaster Deluxe
4. 2016 Squire Affinity Telecaster with CS Twisted Tele pickups.
