I can't afford a tube amp right now. The cheapest ones I want are upwards of $200-$250. I know that a solid state amp isn't going to sound as good as a tube amp, but will it sound good enough to play typical worship style music? I can get a decent solid state amp for like $100-$120 at local pawn shops around my town.

Secondly, how many watts do I need (tube and solid state) to fill up a 2500 sq ft room if I Mic the amp? I would need the sound to be fairly clean as I'm going to run pedals to it.

EDIT:
The tube amps I was looking at were the Bugera V22 or the Fendor Pro Junior III. Both are small in size and W. I've seen the Bugera go as little as $200 and the Fender Pro Junior is more like $200-$250.

Ummm....1?

If you're miking it, wattage isn't really a critical factor.

LOL. Thanks. I wasn't sure if I would need a certain number of Watts to push enough power to the mic... also, I wasn't sure if the wattage would affect the sound quality... like maybe there wouldn't be enough low end if there weren't enough watts. I'm kind of an amp noob, though I have been reading a lot about them.

It's funny, I've been looking at a lot of amps on craigslist, and I literally just found a fender pro junior that I might be able to afford right after I posted this. Still interested in thoughts as I might not get the amp, but keep that in mind.

Bathroom / Bedroom Playing = 5-10w
10x10 room = 15w
Anything else would depend on your environment and if you're playing with others in a band or just jammin along with a record (yeah, I'm that old that I use to jam along to records).

A good investment that I see a lot of folks going with are bi-watt or tri-watt adjustable. With the flip of a switch, you can go from 15w to 30w or 25w to 50w. Some of the half stacks can be set at 50w or 100w.

Invest in something now, that allows room to grow

Hey, how about if you explain to us the volume difference between 5w and 15w?

What is this nonsense? Pretty odd arbitrary numbers here, especially considering most bedrooms are close to or bigger than 10x10.

Not sure what your situation is but a used Epiphone Valve Jr can be had for $120 or even less. Its a killer lil amp. Super simple and it sounds great. Without a doubt I'd take one over a $200 Pro Jr. If you're in a band situation it'd be too limited though.

Are the numbers you're quoting for a solid state amp or a valve amp? Because I have a 15 watt valve amp in my 10 foot by 10 foot room at home and if I turn it up you can hear it across the road! It hurts ears to be in the same room!

I was wondering why he mentioned bathroom amps being a certain size. Amps simply should not be in bathrooms. Also, don't worry, those numbers are total bogus and should be disregarded.

Crate blue voodoo, vyper tube or valveking, all good tube amps with in your budget. If volume is that much of a concern I say a used flextone.

Volume difference between a 5W amp and a 15W amp is subjective you probably wouldn't notice it by ear. A 15W and a 100W have a perceived difference in loudness that is about 7dB, so I couldn't see the difference between a 5W amp and a 15W amp being more than 1-2dB louder. Kind of wish I had a dB meter I would test my 5W and 15W and tell you the exact difference.

But what if you have the urge to practice Eruption while you're taking a dump?

To OP: Invest in a tube amp. Please. If you need an amp because you don't have one at all, invest in something crappy until you can get a tube amp. You'll thank yourself later

As far as wattage goes, a lot of people like to use the 4:1 ratio. So a 25 watt tube amp sounds about as loud as a 100 watt solid state amp.

For a church? You could get away with like 10 watts (tube) and not have to plug into the PA system. If you're miking up, it doesn't matter how many watts. You just need to be able to turn up to the amp's 'sweet spot' (where the amp starts to sound good, basically).

For me, that's around 3-4 volume on my Fender Champ 25se (25w tube). For my Marshall AVT50 (50w ss), it's at about 5-6 volume.

So my recommendation would be to actually get a smaller/medium sized amp so you can get up to that sweet spot without blowing everyone's eardrums out.

For reference: As the lone guitarist in my band, I filled up an entire reception hall (rather large. It was the kind that sat around 300 people) with my 50w solid state turned up to 7. I doubt I'd have had to turn my tube amp up past 4.

Instead of a bad solid state amp why not get a Line6 POD or something of the sort? If you have the ability to Mic an amp you should be able to plug that in direct to the PA.

Otherwise do as Mjones1992 said save up for a Tube Amp and get something super cheap in the meantime. Haggle away as well.

Good luck

It's not subjective at all. There's a set of rules governing how much you need to increase power to get an increase in dB.

It does depend on the specifics of the amp, though, so comparing one amp to another isn't apples to apples.

But saying "5W is good in situation A, 15 W is good in situation B" makes practically no sense from either end.

Apologies, I know, I'm usually one of the guys that's doing the explaining...

Everything else being equal, there is a 4.771213dB volume increase when going from 5w to 15w. While that's not entirely insignificant, let's put it in perspective.

Using a Celestion Vintage 30 as a frame of reference simply because it's a very common guitar speaker, 1w@1m will produce 100dB.

Thus 2w - 103dB, 4w - 106dB, 5w - 106.9897dB, 8w - 109dB (10w - 110dB) 15w - 111.760913dB and 100w - 120dB (Until the speaker fails, as it's only rated to 60w...)

5w, 107dB is LOUD! Power Mower @ 3' loud. Permanent hearing damage loud.

15w, 111.8dB is louder. But not by so much that it really matters.

And the whole purpose of this exercise was to show that the poster was pulling numbers out of his ass, which benefits no one.

A lot of people are full of crap. Wattage is wattage. Tube amps can often be louder than their claimed wattage because a tube amp will put out more than the rating, hence power tube distortion, while a SS amp will not. But the difference isn't anywhere near 4 to 1, although it can be as high as 1.5-1.


But 5 watts SS or 5 watts tube (measured at output) with the same input signal through the same speaker(s) will provide the same sound pressure levels. Tubes aren't magic.

Maybe save up for a used Excelsior? they're only 300 new, so I imagine that if you got one used it would be within your budget.

Thanks for all the input, guys! I ended up buying the Fender Pro Junior for $175 that I found on craigslist minutes after making this post. I figure, at the very least, if I'm not happy with it I'll sell it on ebay. They're going for anywhere from $200 to $250.

The guy lived about an hour from me, so I had one of my friends pick it up (she lives up there and commutes here for work) and she went out of town for a week. So, I won't be able to get it until next Monday. D:

Anyway, here's hoping it does what I need it to do... which is basically to take pedals well and put out enough clean volume that micing it will sound good with as little noise/hum as possible.
