Yeah, I recently bought the Vox AD60 head.
It's the best practice/recording rig I've ever used!
I use my tube amps at my rehearsal studio for practice and gigging, but my recording gear is in my apt studio now, so I'm forced to use a modeling setup. I almost bought the Tonelab, then realized the head is even cheaper, plus you have a power section and tuner, but no cab simulation.
Believe it or not, some settings on the Vox sound a whole lot like a tube amp. Some blow, like any modeling amp. The Marshall, Vox and bassman sounds are better than Line 6 IMO. That little tube they use, mated to the SS power section really does make a difference. Plus the recording out and headphone out have a volume knob on the back of the amp. The variable power that switches between 6, 15, 30, and 60W is awesome for dialing the amp to a suitable volume and still maintaining a cranked amp sound. The best thing about the Vox, compared to others,
is that the OD modelers are put in front of the EQ, just like stompboxes. That feature allows you to really dial in an exact OD character. There's no lack of gain on the Valvetronix. You can do Beatles to VH to Alice n Chains to Pantera on this thing.
I feel like I made a smart decision to go with the head version, since it allows me to forego the Vox particle board & licensed Celestions, in favor of a Bogner large 2-12 Vin 30 cab. That makes the fidelity of the amp much better than the combo.
