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.

My local Behringer tech friend does not have it - I am contemplating doing some mods to make it a useable unit - then again, maybe I will just put it on the local Trade Me site (NZ Ebay) and see if I can get some money backĪnyone with a schematic - factory or otherwise email me - I will not say where I got it okayĭo yourselves a favour DO NOT BUY one of these - build the B K Butler Tube Driver instead No wonder Behringer discontinued it - does any one have a schematic for it? it sounds like a badly biased germanium Rangemaster - you know, that shitty gated distortion effect in comparison to the smoooooth sounding B K Butler Tube Driver. It has a Coolaudio brand chip - unsure what it is - looks like a quad opamp SMD device in place of the B K Butler TL072 or 4558 dual opamp.ĪND.

It has a crappy single knob tone control in place of B K Butlers HI and LO controls. I have to tell all here that this is not even remotely similar to the B K Butler Tube Driver.įirst it runs off 9v dc, NOT 12vAC (which is converted to +12vDC and-12vDC in the B K Butler) I purchased a Behringer VT911 (reputedly similar to the B K Butler Tube Driver), took it apart AND.

Tube Driver Bottom PCB layer parts placement and bias mod How does it sound? I did not care for it - but then I have been spoilt by a real tube overdrive ( 250v dc plate load feed as opposed to this 12v beastie) I think you may be able to improve it's sound by using a higher spec op amp such as the excellent Burr Brown OPA2134 and by using better quality metalised polyester or polystyrene film capacitors - who knows?Īnyway - big drum roll. Good luck if you want to build it - it uses a double sided circuit board. It uses a TL072 op amp and 47k plate load resistors and many other subtle changed components - more later. I have not redrawn the schematic yet - it should be up in the next few days - it is not the same as ANY of the many schems floating around on the net by the way. The additional bias control pot is mounted above the input socket on the rear panel - I preferred it without the additional bias resistance and capacitance - but others may find this B K Butler mod useful. There is no mojo components in here - just cheap mylar greencaps and standard metal film resistors - so It won't sound very good - tell David Gilmour and see if he cares - he has two of these exact same pedals in his Pete Cornish pedalboard The earth pin on the input socket is connected by a parallel connected 100 ohm resistor and a cheap 100n mylar capacitor to the chassis near the front of the case. The input and output sockets are isolated from the chassis by plastic insulating spacers.

You will need a suitable 12vAC power pack for this pedal - the original has a small toroidal mains transformer fitted internally near the front of the case. This was traced from a recent B K Butler pedal and has the bias pot modification which alters the voltage on the cathodes of the 12AX7 tube.
