The guitar sound of the first Black Sabbath Album is actually the result of a number of key components, Tony himself not withstanding, but it is also the sound of the LA100BL plus a Dallas Arbiter Range master pedal that Tony used at the time, allowing him to push the front end of the amp into overdrive giving him his signature distorted tone never before heard. The pedal functions in the same way as his legendary modified Range master - with a significant bass cut and mid boost, but we've included a little more gain and EQ options to make it more appealing to more players looking to find their own sounds. The TI-BOOST is a simple pedal - it has a Drive and a Volume control, along with the ability to dial in the Low and Hi frequencies as well as a mid switch that gives you a couple of different Mid frequency options. Sonically the combination of the LA100BL, the LA412 and the TI- BOOST pedal gives you a guitar tone recognised for decades around the world by millions.
