    My third foray into valve heads, and third time, as they say, is the charm.

    I like the form factor of this guy, it doesn’t make weird noises, and it got that fuzzy warmth. Trying to decide if I want to mount it on the fliptop cover. D15A50B5-6768-4C66-9685-D488372CEB69.jpeg

    Cool. I'd like to try that Feedback knob

    It probably does not do what you think.

    The forerunners of this amp had a switch or button that modifies the upper knee of the bass control. This circuit is labeled mid-shift, but if you have the bass control fully CCW, the switch has no impact on the sound. Old Trace Elliot V-Types use the same circuit.

    I believe the Feedback control on the Little Stubby is variable version of the mid shift control.

    I like it :thumbsup:.

    This description is consistent with the tone stack in the Mk1 LB30 and CTM30, but not for the Mk2 versions of these amps. IMHO, the tone stack in the Mk2s seems to function more like a Hiwatt than a Fender.

    yes, exactly. I have been using it sparingly because, cranked, it tends to emphasize those low frequencies and make certain notes disproportionately fat.

    Which makes sense given that Ashdown rose from Trace Elliot’s ashes.
