Here we go Speaker Junkies:
Scroll down about a foot, and you will see my previous two parts if you haven't been keeping up with this thriving blog.
"So Trashed, a lot to say about speakers?"
Yeah.
"You seem to favor Celestion?"
Yeah.
"So because it's a Celestion it must be good?"
HELL NO.
Not all speakers are created equally. Celestion makes some [to put it lightly] shitty speakers. The Rocket 50's are straight up trash. The only thing they are good for is removing the magnets and use it to pick the metal bits off of your floor in your shop. Seventy80's, another junk speaker. Just flat out terrible. There are some others, my Celestion M-70 in my Ampeg is pretty much shit too, but it is workable.
"Trashed, you seem to talk about Celestion a lot. Are there any other good speakers?"
Yessir! Eminence makes some excellent speakers, a lot are cheaper, and to a degree many of them are based off of- you guessed it- Celestions. Swamp Things and Governors are a good combination. I am not a fan of the Legend, but may people like it.
I don't have a lot of time on Eminence, I have owned relatively few.Why? I buy up cheap cabs on craigslist that have good speakers, typically under $200 for a 4x12". That is why I have a shit-ton of K85's and V30's and T75's. Cabs get sold or burned, sometimes kept.
"Damn Trashed, that sure is luck!"
If you look and know what you are looking for its not that hard. The only issue that is sometimes is insurmountable is fitting a 4x12" in your Mustang. What is the lesson here? Know somebody with a truck. It's not that hard.
What matters other than speakers?
Hot-Damn! I thought you would never ask.
Enclosures. There is a whole field of science regarding cabinet design, and stupidly a lot of debate. Why was the 4x12" born? because the speakers were 25 watt, and the heads were 100 watt. So thus it came to be the standard. For the most part sealed cabs offer little difference from each other, the main thing is quality of wood. MDF for me is a no-go, and what you want is 3/4" 13 ply Baltic birch. A good seal is to a degree an important thing as well.
Regarding the open-back or ported design, it gets jumbled fast. I don't even want to get into that. Maybe another blog sometime in the future.
So what do you pay for in a cab? The largest portion is the speakers, the second? the logo on the front. That 'Mesa' logo on the front is worth a few hundred most of the time. [Saying this I own two Mesa cabs and love them]. Wood is to a degree, but not what you think it would be.
Do you need 4x12"s? No. Its actually a stupid thing if you are going to have to haul it around. That is why I have 2x12"s as well. I haul around 2x12"s and keep my 4x12"s around the house/studio.
Ugh. I am soooo sick about talking about speakers.
That wraps up your mid-week edition,
Keep on bitchin' and I will keep on postin'.
Cheers,
Trashed.

2016-08-14 Volume Myths and Boss Pedals
Greetings to the Brotherhood of the Quest for Tone,
The Resentment:
Volume Myths - I am growing tired of the lack of understanding of how wattage is related to volume. It isn't. I hear a large group groaning about things along the lines of, "Will (insert model here) amp be too loud for my apartment?" or thinking that they "Well I want poweramp distortion..."
The truth is that first off, a 100w amp will only be TWICE as loud as a 10w amp. Yep, you heard it, baring extenuating circumstances that is. There are a lot of factors in volume, and wattage is just one. Speakers can make a HUGE difference. A Celestion Vintage 30 has a sensitivity rating of 100dB @1w/1m. What that means is that a V30 being pushed at ONE watt will be 100dB at one meter from the cone of the speaker. that is LOUD. As far a dB SPL goes, there are many variables. Every time you double your distance from the source, it is 6 dB quieter. So that means if you are 2m away from the V30, you are looking at 94dB. Still damn loud. Now lets examine 10w through a V30, that would be 110dB SP at 1m from the cone. according to some references, that is the noise of a steel mill, circular saw, and being next to a car horn. 110dB is 16 times louder than a relatively loud TV.
One final example, 10 watts into a Celestion Rocket 50 is only 105db. That is substantially quieter than the 110dB that you would get out of a V30 but still loud. I must say that the Rocket 50 is a terrible speaker in my opinion, not because of the sensitivity, it just flat out sucks. So if you want to be quieter, to a degree that is, a speaker swap could be the little push off of the edge.
Clearly poweramp distortion is too loud most of the time.
Now as far as how a (insert number here) watt amp sounds quiet, that is a different discussion. My Mesa mkIV sounds much better at TV volumes than my Orange Dual Terror, which i use at 7w-15w usually. My Splawns are both 100 watts, and they preform substantially worse at low volume than any of my other firebreathers. For quiet volumes, it is case by case. It is at this point where my admittedly rather small understanding of tube amp circuit design ends.
The Rambling:
Boss Pedals. I am a pedal whore, no question about it, last count was in the 30's, most $120-$150+ new. There are a few exceptions though. Now boss, they have their strong suits, they are durable as all hell. i am sure you could run one over with a car and not wreck the damn thing (maybe that wouldn't be such a good thing). They were great in the '80's, Especially the modulation and delay (mainly for me the choruses and delays), then, I don't know what happened. Furthermore, their dirt pedals have never been good (other than the whole HM-2 thing), and their dirt pedals have gotten progressively worse. Their buffers are mediocre at best. They have been far from innovative in the last decade, and that is why I am not a fan.
Fifteen years ago, it was different. that was before the millions of boutique pedals and builders were out there. At that time it was them, Digitech, EHX, DOD, and MXR. Time went by and Boss got too comfortable, and ceased to innovate. They are behind the times.
Do i hate Boss pedals? No. Do they make some good ones? Yes. I like some of them, but in most cases there are better pedals for just a few bucks more. Boss stopped making my favorites a long time ago, which are the dimension chorus and slow-gear. They are flat out awesome, but now they fetch stupid prices, and I am not willing to spend that much. Other honorable mentions are the NS-2, DD3, DD6, etc, as well as some of the other choruses. The final mention is the HM-2, I have one and it is great for one thing, that grinding shrill noise that is pushed through a Marshall Valvestate or Ampeg VH140c. I don't care for that tone, but i keep it around in case i get bored.
That wraps it up for tonight, leave your comments or hatespam at the bottom,
