I think any good quality, reliable amp, once dialed in work well with Alembics. That seems evident from the posts of the variety used. Depends on the taste of sound you're after. Hi-fi, growly sounding, etc.
So far I've run my Excel thru a Mesa 400+, nice ballsy amp..see above reference to chiropracter. A Mesa Walkbout and Basis M-2000 head. And have gotten nice sounds from all. I even yanked out an old Vox AC 100 head, Fender pre CBS Bassman, Furman PQ3, Crown and SAE power amps. Various combo's of speakers, 4x10, 2x10, 2x12, 1x15, and 1x12/1x10/+horn cabinet. And gotten nice sounds from all..all different.
I'm currently working with the M-2000/Schroeder 1210 combo, and still exploring the possibilites. The Walkabout/Schroeder combo was also nice, small and light.
I was also amazed that I got a decent sound out of just a Tech 21 bass driver pedal.
And one day I hope to get an FX-1 and SF-2 to add into the mix.
Anyway..that's my .25
