The hype around the Dr. Z Z-Wreck is certainly justified. Originally designed for country superstar Brad Paisley, this simple but versatile clean machine is a powerful addition to any picker's arsenal.
By itself, this amp creates clear, shimmering clean tones, perfect for blistering country licks or funk. The controls are very streamlined, allowing you to build a solid tonal foundation by dialing in just the right amount of brightness with the interaction of the treble and top cut knobs. Past 12:00 on the volume is when you really begin to push the amp and get some beautiful natural break up. Though extremely loud for 30 watts, the driven tones past 3:00 on the volume knob are saturated and full and compliment your guitars pickups astoundingly. Especially cool is the 'speed/comfort' toggle - the 'speed' option runs at 330V and has more clean headroom with a more direct attack, while the 'comfort' option runs at 280v for a mellow and more vintage feel. Very useful for being able to match your own picking style or for using with a compressor without feeling too 'squished'.
And as with any pristine-sounding clean amp, it makes a phenomenal platform for pedals. The tweakable high end lets you dial in the exact amount of brightness needed to compensate for long pedal or cable runs. Got a favorite overdrive? This amp will take it. Got a favorite reverb? This amp will take it.
The Z-Wreck shines just as bright in Dr. Z's huge sounding open back 1x12 combo, giving a ton of breathy punch and sonic spread like classic open back 30 watt amps of yore.
All in all, Dr. Z has hit the nail on the head. Crazy amounts of clean headroom with the ability to break up and rock if needed, the Z Wreck will easily help you attain any tone you've been searching for.
