The Best Amp, the less size, the most powerfull…

Also check out MarkBass amps.
For lightweight, can’t beat the little CMD121P combo, 280W through single 12″ speaker, light as a feather, transparent sound.
Add a 1×12 extension cab (also light as a feather) and you’ve a 500W beast, and you can carry one in each hand without breaking into a sweat.

This best amp a have evere use, it’s not a doublebass amp it’s an “universal amp” for all acoustic instrument, with a neutral sound, Perfect for double bass. I had try with a K&K rockabilly pickup and it’ great great tone and all slap sound ( click) you want due to the litte tweeter. It’s expensive but you won’t regret it. There are 2 version of this amp, 1 with a 10″ speaker and 1 with 12″ speaker.

cheers
