Mozztronics TD-900N Tube Driver
Based on the 900 British amp (model 4100) "Normal" channel preamp. 12AX7 tube at high voltage. Low to heavy crunch.
One of our favourite amps is the 900 British amp, model 4100. This is a 2 channel beast, with a glorious hi gain channel (called the "Boost" channel) and a magnificent lower gain channel (called the "Normal" channel).
We took the whole Normal channel preamp circuit from the amp and fitted it inside a pedal. We use an actual 12AX7 tube inside just as the amp does, but we run that tube at a higher gain than the amp does and we run the tube at proper amp high voltage. We've gone old school here, using circuits that were used to generate high voltage in old time television sets to generate the high voltage for the tube in this pedal.
This pedal does low to medium drive and is great for low gain to heavy crunch, perfect for rhythm guitar riffs and blues soloing. Turn up the gain and you get a lovely heavy crunch rhythm tone. Turn the output volume up to slam the front end of your amp and hear it sing.
This pedal responds like an amplifier would. Roll the guitar volume back and the pedal responds. Dig in hard on the strings and the pedal responds. We like to think of this pedal as an extension of your amplifier.
