If you really, truly need the best tone possible and can’t settle for the watered-down, digitized version of a tube amp, then go with a real tube amp. Most pros use tube amps because they need that sound.
If you’re just staring out, it’s probably okay to test out a few solid state amps first before making up your mind. But once you’ve been playing guitar for a while and try out a tube amp, there’s really no going back.
Tube amps do require some maintenance, but if you can afford it and have the time to dedicate to honing your best guitar sound, it’s absolutely worth it.
