    any one know of mods to make this thing more bass friendly? i got the rack mount running at line and this thing just squashes my sounds at higher gain settings.

    a lower gain tube might suffice but do you guys know if there's a high pass filter than can be bypassed or an input/output cap that can be upped to allow more lower frequencies through? I'd just like to have a simple mod or two to have a tech do that wont run me too much in labor costs. thanks.

    heres a schematic of the pedal version, from what i've read in other forums on the net the rack and the pedal are the same except the rack has a bias pot for the tube and a mid knob in the eq section.

    I'm about to order a tube driver from bk butler and he is voicing it for bass guitar. i also heard he will mod the older pedals too so you might reach out to him at butler audio and ask.

  4. You could also ask @johnk_10 , he's very good at squeezing more bass out of circuits with underperforming low-end.

    I was gonna say the same about JohnK!! I bet it'd be too easy for him to mod one of these;)

    I know he's built clones of these so he probably knows them in and out!

    I think it's out of production now, but the BK Butler "Blue Tube" was a lower gain version of the Tube Driver. It's supposed to sound great on bass, but I don't have any personal experience with them.

    IMO, the blue tube, is awesome with bass. I had one for a while. Used it often and I think its a very cool pedal for bass. I liked swapping the tubes out too to see what type of different tones and sounds I could get out of them. I eventually sold it because it didn't suite my band needs that much. But if I hadn't needed the money at the time, I would still have it. It really is a great pedal.
