It had an inherent tone that I just didn't find that appealing, unlike the Ashdown ABM which has the perfect sound for me with EQ flat, pre-shape on, Valve drive 1/2 way, gain and volume to taste. Sold it and bought a Thunderfunk TF550 and didn't gel with it either! So straight back to Ashdown and happy as the proverbial pig... Just wish they were smaller and lighter.
I'd like a micro amp that'll do the Ashdown thing (something that'll fit in my gig-bag pocket - not the little giant stuff though, seems a bit half baked), but don't think such a thing exists - the Orange Terror bass is probably close (doesn't fit in the gig-bag though), as is the Markbass Tube, but I think a markbass little mark/F1/Ibanez promethean + VT pedal is probably the way I'll go eventually.
I've no experience with any of the heads you mentioned I'm afraid - I'm on the wrong side of the Irish Sea, same as you!
