I have a Pignose Hog 30 Bass amp, and a Roland Mobile Cube. They are both OK, but not great, however, if you feed them with a Tech 21 NYC Sans Amp, they both sound awesome.
I have a Fernandes Nomad Travel Bass that has a Piezo and a Godin A4 Ultra with a Pieso and Lace Sensor. They sound better through the Roland, but the Pignose is louder. The Stingray, and the Ibanez (Active pickups) sound better through the Pignose.
There may be better options out there, but that's what I have. If you're anywhere close to Southeast Mass, you're welcome to come try them both.
Consistency is only a virtue if you're not a complete screw-up.
