One month later and I finally got to A/B my Nitro against a Roadster and a Mark V.
First, if you're looking for versatility then the Nitro is not for you. It can go from plexi-ish to Uberschall with only a gain knob adjustment but it's still a 2 channel amp.
That being said what you get in these 2 channels more than makes up for any shortcommings.
The Mark and Roadster's cleans are very clear and chimey. The Nitro's clean is a little more jangley if that makes sense. It's not as clean as the Mesa's but it has it's own personality. I only use my clean channel about 5% of the time so it's not as important to me as the OD channel and that's what the Splawn was made for.
If you could add a subwoofer and about 50 more watts of headroom to the Extreme mode of the Mark V then you would have the Nitro. I didn't realize how much low end was in my Splawn until I got to hear it next to an amp that I know very well (I played a Mark IV for the last couple years). The high end of the Nitro isn't quite a smooth as the Mark (what is?) but a lead player could still enjoy this amp immensly. It has a footswitchable od1/od2 and a solo switch. Switching to od2 seems to add even more thickness and almost sounds like you've switched from your bridge to your neck pick up. The solo button just adds volume and it has a knob on the amp that allows you to dial in the ammount. All really useable features for anyone who gigs. And gigging is what the Nitro is for. :twisted:
To all the threads that say "Roadster needs moar gain!" get a Nitro. It goes from punchy and woody with the gain at 9:00, snarly and huge at 12:00, to crazy and mushy at 3:00. I liked the Roadsters gain at about 1:00 and the same level of saturation is about 10:30-11:00 on the Nitro. I was expecting these two to be more alike but I think the Nitro is closer in voice to the Mark. It did share the recto hugeness and low end aggression with the roadster but that was about it.
The Nitro is a great amp for me because when I had my Mark IV I always wanted more thickness and bottom end and whenever I played a recto I'd always miss the creamyness and fast articulation of the Mark series. The Nitro has a little of both. It has more low end and a tighter one at that than a Rectifier and a nice smooth mid/high tone for the higher single note stuff.
It's a one trick pony for sure but I'm a one trick player. :lol:
