Since the Tube Driver is a starved plate design, the tube will last much longer (even though the original user guide said they only lasted 2-4 years!). In typical power amplifiers the preamp tubes can easily last 15 years or more with moderate use and 10 years or more with very heavy use. This tube works very well for players seeking a cleaner tone in the lower settings of the drive control. To have a cleaner, more vintage sound, you can substitute a 12AU7 tube, which will clean up the tone and thins out the midrange. To add gain, you can substitute a 12AT7 tube, which will give more distortion and beefs up the mid range frequencies. You can change the tone of your 'Tube Driver' pedal with a very simple modification, which can be completed with only a screwdriver. Here is what an original Tube Driver Users Guide said about the tubes: What it does is compress and color the distortion. A lower gain tube will not necessarily reduce the amount of distortion, but it can smooth and tame it at medium to low drive levels. Since the distortion is generated more by the op-amp than the tube, it would seem changing the tube would have little effect on the level of distortion. Some people find the distortion too rough sounding at low drive settings and want a smoother, cleaner sound.

TUBE DRIVER MODIFICATIONS - Changing Tubes - This is the simplest, most effective mod for a Tube Driver. At some point Butler started using a toroid transformer that runs from 120-240VAC which works with either mains power.
Butler has been making since 2005 could be ordered with either voltage, so be sure you are buying a Tube Driver with the correct voltage for your country. Or, have the transformer inside replaced with one that works with the mains voltage of your country. To run a 220-240V Tube Driver on 110-120V mains power, use a step-down voltage converter. To run a 110-120V Tube Driver on 220-240V mains power, use a step-up voltage converter.
Conversely, if you plug a Tube Driver with a 220-240V transformer meant for the Eurpoean market into a 110-120v outlet, it will only draw 1/4 the power it needs and may not function properly. It will draw 4x the power it needs, causing it to overheat and damage the circuit. DO NOT plug a Tube Driver made with a 110-120V transformer into a 220-240V power outlet.

Later some Tube Drivers and Real Tubes were made for the European market with transformers that ran on 220-240VAC.
The original Tube Drivers were made with transformers that run on 110-120VAC for the North American market. TUBE DRIVER POWER REQUIREMENTS - Most Tube Drivers have an internal transformer that works with the mains voltage of the country it was made for.
