I'm sick of searching! Does the Ashdown ABM have tubes?

Discussion in 'Amps and Cabs [BG]' started by EAdanikDG, Apr 13, 2010.

  1. Whenever I search, I get pretty much 50/50 answers. :rollno: I think it's not tube but i'm not sure. The Valve Drive button is what I think misleads people. Is it just an emulator (like I think) or does it actually drive the (supposed) pre-amp tubes. If it does have tubes, what would be the point in the new Spyder 550; it would be the same amp in a new casing.

    Side note: The new Little Bastard wouldn't be too good for bassists (not enough power) but i'm willing to bet that it'd make a killer guitar amp.

    PS: IDK if this has been said, but the entire Valve series is officially on sale in the UK. :hyper: Don't know about the US though.

    The ABM has a switchable tube section in the preamp.
  3. So the preamp has tubes that can be turned on and off?

    They have a single 12AX7 which can turned on and off.

    The gain to the tube can be controlled by the rotation of the "tube gain / valve drive" knob ;)

    Clean - anti-clockwise
    Dirty - clockwise
  6. The Little Bastard is a tube studio/practice amp, from what I can tell.

    For guitar it probably wouldn't have enough gain for my tastes.

    The ABM has a transistor preamp and a switchable valve overdrive (one 12AX7 valve). The new spyder 550 has an all valve preamp, that means 3 or 4 valves running at high voltage instead of the lower voltage ABM.
  8. So it's just to provide a tube driven sound, not an actual preamp? Basically like an EBS ValveDrive or the Markbass Watchamacallit?
