man where to begin..an all tube tiny little guitar amp that has about one watt of power to get a true saturated feedback fully cranked marshall sound but at nice bedroom levels ..good for recording full amp sounds without going deaf

Part 2 – Sounds/Tone
The Marshall AS50D is a 50 watt acoustic amp that features two 8-inch speakers. In this video, I play snippets of different songs and demonstrate some of the features such as Chorus, Reverb, and Anti-Feedback. If you are more interested in the technical specifications and such, check out Part 1:

I know that a tube amp with 10 or 15 watts can drive a cabinet that is rated for a minimum wattage of much higher than that of the amplifier. But solid state can’t necessarily do this. What is the difference between tube and solid state watt amps, and how big of a cabinet can a small 15 watt amp drive?
A watt is a watt is a watt…period. Here’s the formula for calculating power:
P = E * I
where:
P = power in watts
E = EMF in volts
I = Current in Amperes
There’s no variable for "tube" or "solid state".
Now most folks will agree that when you turn a tube amp up it will sound louder than a solid state amp of the same wattage. This has to do with how a tube handles a signal vs a transistor when they get to the limit of their operating range. A transistor will clip the signal abruptly, and most folks don’t percieve that as a "good" sound.
A tube on the other hand will start compressing the signal as you increase it’s drive level. By doing that, the average levels of the signal are higher, and we percieve that as louder.
It’s basically the same thing that radio stations do to their audio (and now mastering engineers) to make the signal stand out.
Now, the question of "how big of a cabinet…". Well, I suppose you could hook up a cabinet that’s rated for 1000 watts to your amp, and al long as the impedances are matched it would make noise. And that’s true of tube or solid state (again…a watt is a watt).
Don’t get too hung up on wattage numbers on speaker cabinets. What really impacts how loud a speaker system can get is it’s efficiency. In other words, how well does it turn electrical energy into acoustic energy.
Very high wattage speakers are usually pretty ineffecient compared to lower wattage ones. So, it’s entirely possible to hook your amp up to a cabinet rated for 50 watts, and it’s louder than the 1000 watt cabinet.
You usually see the "minimum recommended wattage" spec on high fidelity speakers (because they trade efficiency for accuracy). I don’t believe I’ve ever seen that on a guitar cabinet.
As long as you’re not mismatching impedances, feel free to experiment.
Good luck.

What are some recommended funk guitar effects to use? Im trying to pick four boss pedals and one boss wah and keep it at that. So basically, what should those four pedals be?
I’d recommend a compressor (so your mutes don’t sound like ‘paper’), an overdrive pedal to add a tiny bit of fuzz or as boost for solos and maybe an EQ pedal.
I don’t think 4 pedals + a wah is necessary, just the compressor and the OD + wah is enough if you ask me..
I’m a beginner guitar player, and I already have an acoustic guitar, but I would like an electric. What are some good guitars/amps that are about $100-$250? Also, what other equipment would i need besides the amp and guitar?
Epiphone, Squire, and B.C. Rich. Crate makes really affordable beginner/practice amps, and for a little extra you can get a Line 6 amp…they are very good sounding and crammed with features. You will want to get a few cables, pics, extra strings, polish, a tuner, and a case or gig bag for the guitar.
I’m looking for a Fender amp that gives awesome clean sounds, the overdrive doesn’t have to be the best but fair.
I heard the Pro/Twin Reverb and Hot Rods are pretty good.
The amp i’m useing now is a Vox VT30
The twin reverb is good but it doesn’t have a distortion channel at all, so i’d probably have to use a pedal with it

I want to get an electric guitar but I don’t have enough money for the guitar and an electric amp. I already have an electric-acoustic guitar and acoustic amp. Would the sound be good if I used the acoustic amp with my electric guitar?
The sound will be fine. Just keep in mind that the acoustic amp will not have as many "rock and roll" effects as an electric amp.
