The TD has a very unique voice that I have never heard another overdrive replicate. It can be difficult dial in a tone setting that hits the sweet spot, and some people find it finicky and hard to get along with due to some design issues, but in the right setup, with the right amp, nothing sounds quite like it. It is not very versatile sounding through some amps, but exceptionally good with others. At low drive it can deliver a Fenderish smooth gain boost or a bluesy overdrive. At high gain, it is very reminiscent of the lead crunch tone of a Marshall JCM800 amplifier. It generates anything from a smooth, light overdrive tone, to a classic rock-style heavy distortion. It has evolved over the years and there are many versions (a list can be found HERE). Around 1978 Butler designed and began making an early version of the Tube Driver, one of the first tube overdrive pedals. It was designed and built by audio electronics engineer B.K. BUTLER REAL TUBE OVERDRIVE - The Tube Driver is a booster/overdrive pedal with an IC and vacuum tube driven preamp circuit inside, used by guitarists such as David Gilmour of Pink Floyd, Eric Johnson, Billy Gibbons, Joe Bonamassa, Joe Satriani, Kenny Wayne Shepherd, J Mascis, David Holt, Keith Urban, and others.

Ultimately, it depends on your comfort level and application. The reset also tends to be quicker on a single-stage trigger than a double-stage trigger. Others opt for single-stage triggers because your finger doesn’t need to travel as far before the trigger breaks. Some people prefer a double-stage trigger, because they can “prepare” the shot by pulling the trigger through the take-up to the wall and then fire at the exact moment they choose.

If you master this mechanism, you can make quicker and more accurate follow-up shots. You can then pull and fire or release the trigger and not shoot. Or you can release the trigger and not fire the weapon.Īfter firing a double-stage trigger, you can release the trigger just enough for it to reset.

Once you’re at the wall, you must apply additional pressure for the trigger to break. They’re most common in rifles, but you certainly can have a single-stage trigger in a pistol as well.ĭouble-stage triggers usually have a slight take-up where the trigger is looser until it hits a second stage of resistance, called the ‘break wall’. Single-stage triggers have one consistent pull weight from start to the break.
