Well, that didn't work out so great.

[smitty_p]

So, have you ever decided to do something that seemed like a good idea at the time, but kinda didn't work out so well?

Has it happened to you?

It happened to me.

See, I learned that a lot of the audiophiles like to put sound padding in their closed speaker cabinets. Apparently, its good for the sound in that discipline.

Well, so I figured I'd try it in my little Vox AC4TV.

So...ummm...yeah...don't do that.

The amp is closed-back, but it is ported, so there is pressure relief from the backwards movement of the speaker. But, the padding killed any desirable reflections within the amp that could come out the front ports. In short, the whole thing seemed just a little less lively.

I've taken all the padding out and returned the amp to normal. It's not a huge difference, but it does help liven the thing up just a little.

I'm glad the isolation cabinet I'm building will allow me to put the mic far enough away to pick up some amp resonance.

BTW, there are no pics because I'm trying to pretend it didn't happen!

Yeah, three times in fact. Thank goodness for divorce court!

Smitty, I recall I mentioned in a thread somewhere about not putting stuff inside a cab once. There are formulas for cab size and porting dimensions along with the use of internal baffles too. I'm quite sure that the folks at Vox worked this out for that little amp to maximize projection. Internal sound absorption within a guitar cab has dulled many a cab. Guess ya found that out huh?

Really? Well, whadya know?

I must have missed that post. My bad.

It all worked out okay, though. Unless I'm doing something that I'm really sure about, I try to leave myself an "out" in case things don't work out.

Anyway, it was an interesting discovery.

Yeppers, it's fun to mess with stuff and find what does what. I had a line on some great birch plywood for a time and when I was building some amps I found that to be the most resonant wood around. All 3/4" stuff and that was just the right thickness for an average single 12" and also for the twin 12"ers I made. On the single 12"s I'd discovered that was not too good for the rear baffle and switched to 1/2" solid poplar for that part. With about a third of it on the bottom leaving a good gap to allow for air flow to the tubes.

I kinda wish I kept one of those amps I built. Gave one to the shop owner and sold about a dozen more to some of my customers that liked the one the owner had. I hadn't really planned on making so many as that one I made for the owner was meant as a gift, but others would play through it and thus I made more. Real time consuming as the chassis was hand made from sheet steel and blued (like a gun) in a large tank. And the whole amp was point to point wired. So if you ever come across a tweed or black tolexed amp with a silver horse head and a "G - H" on it, that was one of mine.:)

Yup.
Trading a 1968 SG Special for a 70's Ibanez Custom Artist.
It seemed like a good idea the day I made the trade.
I soon regretted it.

A lot.

Well, it is a learning experience!

Smitty, you got off easy.

(13 January 2005, Croatia) One fateful afternoon, 55-year-old Marko
retreated to his semi-detached workshop to make himself a tool for
chimney cleaning. The chimney was too high for a simple broom to work,
but if he could attach a brush to a chain and then weigh it down with
something, that would do the trick. But what could he use as a weight?
He happened to have the perfect object. It was heavy, yet compact.
Best of all, it was made of metal, so he could weld it to the chain.
He somehow overlooked the fact that it was also a hand grenade.
Marko turned on his welding apparatus and began to create an
arc between the chain and the grenade. As the metal heated up,
the grenade exploded. The force of the explosion killed poor
Marko instantly, blasting shrapnel through the walls of
the shed and shattering the windshield of a Mercedes
parked outside. Marko's chimney was untouched.

There's a valuable lesson there.

So, what I understand is if I built an amp out of bricks it could withstand the blast of a Croatian grenade!

It's funny you say that, because I did that with my Vox Lil Night Train cabinet for that precise reason - to dull the sound a bit. I don't know what the AC4TV cab is like, but the 10" LNT one was bright, and boy did it HONK. Sounded like it had a bit of a head cold. The padding dulled that quite effectively and made a noticible, positive difference. I only did this mod after hearing that so many others did it before me.

I'm glad mine turned out well, but it could well have just gone horribly pear shaped! Oh well, as others have said, it's all a good learning experience.
