The JH-1 features a passive (true) bypass switch, preferred by many purists since it eliminates any trace of the effect when the unit is clicked out of the circuit. The JH-1 is powered by a 9 volt battery, and also features an external 9 volt DC input jack and a status LED.
Construction aside, it's sounds you want, and the JH-1 delivers! To maximize the signal between your guitar and amp, the Jackhammer offers the following controls:
Crunch or Lead mode
Gain
Master Volume
Contour (clockwise cuts upper mid/treble, counter-clockwise cuts bass/low mid)
Contour Frequency
Bass and Treble
The EQ control is especially tasty, allowing you to get some great tonal variations. And there's lots of volume inside this rugged unit! So whether you go for crunch, singing lead tones, or an all-out banshee attack, you're bound to find what you need with the JH-1.
