Which small, lightweight D class head will sound like my Ashdown ABM500?

    I currently gig a Gen 1 Ashdown ABM 500 that I bought circa 2001-ish. I love the amp and the sound that I get out of it but I'd love to move to a super lightweight head with a size and weight along the lines of a Markbass LM III, GK MB500, etc.

    I actually currently own a 6lb Carvin BX500 and no doubt it's a great, lightweight amp and it's loud as heck but...I just can't seem to get that sound that I'm looking for. The Ashdown has this warmth, depth and grunt right out of the box that I can't seem to pull out of the Carvin even though it has a pretty extensive EQ section. And trust me, I have A/B'd the heads on the same cabs (either a pair of GK Neo 1x12 II's or an Eden 2x10 XLT) for hours and I just don't think it's happening.

    So, which small form factor class D amp will get me closer to the "Ashdown" sound? GK, MB? I do see that Ashdown has a small MI bass head. Does anyone here have any experience with them?

    Not sure if anything will sound just like the ABM, but the Aguilar TH500 may be the closest...?

    Maybe GK MB Fusion, either 500 or 800. The three-tube preamp warms them up pretty well.

    Am I stating the obvious....Ashdown Rootmaster 420 would, as a wild guess, come closest in tone to your other Ashdown head?

    I got an Ashdown MiBass 550 recently and it comes pretty close. I wish it had the valve drive on it. There's one on Reverb, but local pickup only. Its only about an 8 hour drive from CT :smug:. The Bass Place is selling the MiBass 2.0 for pretty $169.99. They occasionally put them on ebay with a $99 start bid. May be worth the gamble or at the least, a cheap backup head. I listened to some demos on youtube and it sounds pretty good.
