GUITAR V BASS AMPS

Why do they do that thou?!? Its not to let the heat out is it?!?
I read a Bit about speakers today and it said:some of the power or energy turns into heat and some into sound??

That photo is of a partially open back guitar amplifier. Guitar cabinets aren't designed for reproducing the bass range, so you will see many open back and partially open cabinets. Bass cabinets typically fall into either sealed or ported designs in order to support and correctly reproduce bass frequencies.

Any moving object is subjected to friction, which means you need to deal with heat dissipation. Any powered system is going to have some portion converted into work and some lesser amount will be lost in the form of heat. Unless you are dealing with very high power applications, you shouldn't need to worry about this. Just remember, don't block the ventilation openings or fans used to cool your amplifier, and you should be fine.
 
Common amp controls:

-Gain/Drive/Over Drive = add to make input signal from instrument more intense, from clean to grindy to distorted.
-Reverb = spatial ehhancement, echoey, but not really. Hard to describe.
-Tremolo = Volume pulsating up and down
-Vibrato = Pitch (frequency) shifting. Think whammy bar.
(Fender swapped what the tremolo and vibrato controls do to differentiate their amps from the rest.)

The last three are typically not used for bass amps.
 
people have played bass through guitar amps and vice versa. There can be some unconventional sounds to be had there if you're okay with playing within certain limitations and accepting certain risks. The simple truth is, that musical instruments are pretty niche and the whole hobby starts off at pricey and keeps going up from there. If you're just starting out and are hard pressed to afford anything "proper", you run little risk getting the cheapest thing, accepting that its tone will be unconventional and using it at low volumes - there's no shame in working with what you've got.

But in all honesty, good sound will encourage you to play more. If you've got a bit more dosh to blow on a thing like this it WILL pay off for a proper bass amp, even if it's down the road.
 
How did you find out about the special sweet guitar amp to use?!?
rehearsing in a dorm room. The band's guitar player was using an acoustic, and I plugged into his super. Sounded good, so we used that setup a lot. The band was playing a mixup of rock & roll, folk-rolk, outlaw country, a little blues. I learned that if we could make the music work in that quiet setting, where we couldn't hide the problems in the noise, it was easy to perform at volume.
 
Rocktile PG-10 model
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.
