The really cool part of the pedal’s design is that you can switch tubes inside the unit to give the pedal different styles of distortion. By starving the tube of voltage and controlling what low voltage it operates at, you can force the tube to distort at much lower volume levels than what is traditionally possible in guitar amplifiers. Inside the pedal, the tube is set to work at only 12 volts (much less working voltage than what tubes are hit with inside a guitar tube amplifier) in what is referred to as “Starved Plate” voltage. The IC chip overdrives your guitar’s signal and then sends it to the tube to “color the sound” identically to tube overdrive. If you know the sound of turning your tube amplifier up and getting the tubes to sag and create distortion, then you’ll understand the general concept of this pedal. Thank you so much I'm going to love working with it.Basically, when you run your electric guitar through a Tube Driver to your amplifier of choice, it is essentially acting as if you are running through a small overdriven tube amplifier and sending its overdriven tube signal to your guitar amplifier. And I can't believe you got it to me in four days. You were right in suggesting I get the Bias model. You have done a wonderful thing for musicians and music by inventing and building these.
for a bit of Gilmour, honestly instant 'Comfortably Numb' tone - just out of this world and loud as all hell :DCodyHi BK,Just wanted to let you know, I received the TD on Saturday morning and was able to use it on the gig Saturday night. It adds a whole other dimension and is hard to imagine the pedal without. absolutely blown away by the sound especially with the Bias knob.
Well now I have tried it and it's AWESOME!! The Bias dials in everything from creamy to nasty!! There's a huge variance that I'll have to find my 'sweet spots' depending on which amp and which guitar I am using.BrianDear BK,Gday there BK, just got the tube driver in my hot lil hands this morning.

It does not change the EQ directly but because the way the tube responds can be varied you will hear EQ differences at various settings.Most players find a 'sweet spot' about 2:30 - 3 o'clock on the control.All in all, it is a 'pro tool' type of control that each player can set to their own subjective taste.User Comments regarding the Bias mod upgrade:Hi BK,I got the Tube Driver with Bias last week and was too busy to test it out. The Bias control also adds dynamics and allows you to custom match your Tube Driver for any particular pickup/amp combination.Technically it varies the electrical 'strength' of the tube and that affects gain, texture and dynamics. Just go up or down a few clicks and he nails what he wants. Eric Johnson used to spend a lot of time looking for perfect tubes to use in his standard Tube Drivers, but now he can just set the bias easily with the stock tube. Very versatile.The Bias control is very helpful as it adjusts the amount of current applied to the cathode of the tube. It has the special Bias knob modification done by Butler himself. It is autographed by BK Butler himself with an engraving on the back. This is an excellent pedal in great shape.
