Mozztronics TD-900N Tube Driver

One of Mozz's favourite amps is the 900 British amp, model 4100.
 
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.
