Yes a lot of Nik's amps have the post phase inverter master volume. If you don't want too much volume you might want to go with the 18 watt Marshall clone. But remember, with a master volume you can go with a higher wattage amp if you want that distorted sound. Frankly, I prefer to use pedals because if you want that clear sound when you turn your guitar's volume down you'll get it. The post phase inverter mod is the only way to go because it keeps the basic tone of the amp intact whereas, many amps that are on the market don't do this and it is next to impossible when the gain is up to get a clear sound. If you want the Marshall sound, go with the Marshall clones. If you like the Fender sound, go with the Fender clones and for the hybrid go with the Trainwreck, Matchless and Ceriatone Overdrive.
