3 different amps...one is a solid state, one is a modelling amp with a power amp tube, and the other one is an all tube amp.
It would depend on what you need. You want something that could take pedals well? I'd go for the Pathfinder and the Cub 8. For bedroom use, I haven't turned the Pathfinder's volume control past 12oclock. Tingin ko mas malakas yung Cub 8 in terms of volume.
If you need the amp/effect models, go for the Vox Valvetronix. Or maybe consider a Roland Cube. They're really good sounding amps.
The best thing to do would be to try them all. Kasi it would be a bit subjective dahil iba iba silang klase ng amps. If were talking about Marshall MG15 versus Vox Pathfinder, the Vox wins handsdown.
Pero sa akin, since i don't need modeling, I'll go for the Pathfinder. But if I got a bit more cash, I'd go for the Cub 10.
