I wonder how it sounds!
The guitar amp Tiny Terror gets excellent reviews.
The only digital amp (or class D?) I've ever tried is the Yamaha BBT500. That is an excellent sounding amp with a very convincing tube sound (plus many other sounds)
But the downside to this amp -in my opinion- is the lack of dynamics. I really like what powertubes do with your sound when you make a difference between playing your bass soft or hard.
Okay, the Terror Bass does have pre-amp tubes, but I doubt if that delivers the dynamic response I would want.
But again, I wonder how it sounds.
And I'm pretty sure my back would approve of this amp straight away
