Re: Question about tube overdrives
The Vox cooltron stuff is cool. The Big Ben is a good blues overdrive with strats. The bulldog two stage od/dist is a bit toothier, but has a cool, Van Halen-esque bite to the high gain sounds. I bought the Big ben, but sold it after a month as the G2D classic was better.
Baritone: The Vox tonelab stuff uses the 12ax7 at very low voltages for replicating the power section characteristics of class A and class AB amps, and has nothing to do with preamp gain for the amp or pedal models.
I tried the MI audio Tube Zone into a Splawn Quick Rod yesterday. It was cool, and had great low gain tones, as well as huge gain on tap if you wanted. For me, the high gain sounds were very compressed, and kind of reminded me of a big muff but tighter, without the 'fuzz' bottom end. I tend to get sick of the sound of big muffs after playing them for a while, and the tube zone's high gain sounds to me like a big muff I wouldn't get tired of hearing. It'd be a great choice for anyone doing stoner rock.
The tube zone is a very fat sounding pedal, though. MI audio makes a solid state equivalent called the Blues Boy deluxe, and I preferred that over the tube zone as it was tighter and less invasive of the amp's tone. Both would be cool, though.
