Anywhere you look online, it very clearly says, "Rocktile PG-10 Rocktile
guitar amplifier".
Also, it's not 10 to 25-watts. It is a 10-watt
rms amp. RMS means root mean square. That's the average amount of power that the amp will put out. Peak power is normally twice that, so who knows where they come up with the 25-watt peak. I would call it "marketing". NEVER compare amps by peak power - too many ways to fudge it.
Also, odds are any amp that is just 10-watts is a guitar amp. A 10-watt bass amp is loud enough for bedroom practice and that's about it. It would not be useable in a group situation whereas a guitar my be just fine with that amount of power.
When the @Coolhandjjl was talking about an "open back" on the amp, he's talking about the area where the speaker is. If you can see the back of the speaker, that is NOT a bass amp. Bass amps are either totally sealed around the speaker or they have tuned ports.
Open backs allow too much speaker movement too quickly when reproducing bass notes and speakers tend to tear themselves apart fairly quickly if you go above bedroom levels of volume. Whereas a bass may move the speaker like crazy, a guitar through that same speaker with the same settings may just make it shake a bit. So stay away from open back combos and speaker cabs.
