We have found it impossible to describe every mark on an instrument or amp that is not in the "mint" category. *Please note: we do our best giving descriptions of used pieces. Then we burn it in for an hour or so before we ship so that there are no surprises.” “We test every used pedal when we buy it and bring it up to our standards before we offer it for sale. There is a large volume of information available about the origins and evolution of this pedal, anyone interested can easily read up on the whole story!” “Great overdrive pedal with serious credentials. It's like changing the types of tubes anywhere from a weak 12AU7 to a blistering 12AT7.”

The Bias control allows you to adjust the tube characteristics over a wide range.

The custom variable "Bias" mod version is available with an additional custom 5th control (I’ve made several of these for Eric Johnson, David Gilmour, Billy Gibbons and Joe Satriani) is available for $125 extra as it takes more time for me to build. This insures authenticity now and in the future! Then I engrave my signature on the bottom of the case.

The design and sound is the same as the original (as supplied to Eric Johnson, David Gilmour, etc) but with improved parts such as Switchcraft all metal jacks, click pots, etc.Įach unit is hand built to my specs and I personally check out each Tube Driver to perfection. I personally autograph each Tube Driver on the bottoms side. I'm hand building only limited production numbers every week. “Due to the continuing requests for my limited production original design Tube Driver pedal, here are the details:

The treble pot's range definitely isn't narrow.Used BK Butler Tube Driver with bias mod conversion serial number 0510412. I used the EffectsLayouts board as a guide but haven't built that one to compare. The bass pot doesn't seem to have as significant an effect as I expect - I haven't spotted an error in the tone-stack but there might be one. I'd like to try a 12AU7 in it but all I have laying around are 12AX7s. I haven't noticed the box getting warm, but I haven't had it on for more than an hour or two. It consumes about 150mA 12V, but at startup draws >350mA for some seconds as it warms up. It uses an LT1054 like EffectsLayouts design. Board-mounting the bass and treble pots instead is probably the way to go. It could use some improvement - the board isn't well supported so dropping the pedal could break the tube. Here's the layout file if you want to play with it. Poor planning, needs more work, but since the build runs I just jammed in a box up-side-down instead. The original plan was to board-mount the level and gain pots with the tube facing down and the DC jack above it, but I tried and it didn't fit.

The top-side has 3 jumpers, plus one on the daughter board. That is to say, a double-sided board isn't necessary, it's just for mechanical strength. I made a double-sided board so I could effectively solder wires and the daughter-board underneath, but of course there are no vias, so they still needed to be soldered to the underside. I wanted to see if I could squeeze it in to a 125B, so I made a layout using ExpressPCB Plus and etched the board. Well, if you don't mind a 1590BB there's this.
