Mozztronics EX-1 Expander Drive Pedal
Mozztronics EX-1 Expander Drive Pedal- Hand Made in Australia
Diode clipping to ground with adjustable asymmetry. EXPAND control for dynamic response. Treble cut to treble boost TONE. Hand made in Australia.
There are many variants on two common designs. The tube screamer uses diode clipping around an op amp feedback loop. The distortion + has diode clipping to ground after the main gain stage. Often the distortion stage is followed by a low pass filter to smooth off the sharp clipping caused by the diodes. While these designs sound good, there are some features you cannot "dial in" with these types of pedals. Some people use different diodes with different forward voltage to get a different sound.
This is the Mozztronics take on this style of pedal. They use the diode clipping to ground arrangement, but have added adjustable asymmetry, and an expansion control which controls how much the character of the distortion changes as you push the guitar harder.
This is great for crunch rhythm tones, and gives nice drive sounds when driven hard. This works great in combination with the TD-1 Tube Driver for a really smooth lead sound.
Suggested setup: Use the EX-1 before the TD-1 in the signal chain. Set the EX-1 for crunch rhythm and the TD-1 for lead. But there are no hard and fast rules—experiment with the order of your effects to find what you like.
