The Acoustic Club

Hey everyone,

I just bought a B200H and a B115 a few days ago and love it, but I think I may have a problem.
Even without my bass plugged in, the amp makes a pretty decent amount of noise when the gain and volume are turned up anywhere past 1 o'clock. Being relatively stupid when it comes to amps, I don't know if it's supposed to be like this, or if there is a problem with the head. Any help would be appreciated! :)
 
Maybe it’s the CPA in me but I wonder if Vetchking or any of the other experts on Acoustic have some basic information about the original company. Where and when started, what year started, year ended, # of employees, # of dealers at peak, first amp/first bass amp produced, etc.
 
I've messed around with it a bit, and no matter what how I set the EQ, there is a ton of hiss with the gain turned up anywhere, and this is without my bass plugged it. I'm really not even cranking it, either. I guess a trip to GC is in order?

Sometimes you scare me, you have been around the "acoustic" stuff for years.

One of the best sites I've ever read is the unofficial acoustic site. They have all the information you ask about.

The only trick is you have to push the button and read.

It's almost all there. There is a book on the way........ It will be a while.

Have a great one............. George........ Later

I returned my B200H to GC awhile back and got a new one. i was getting a very bad hum coming through the amp and speakers with nothing plugged in and all volume down.

So if you are getting any hiss etc. w/nothing plugged in take it back.

LOL!! Sometimes I scare myself. Anyway, yea I was a big fan of Acoustic back in the late 60's and early 70's but I had no interest in the business end of the amp-making biz. And then stopped playing for many years. Anyway, as you can imagine with two kids in college and two jobs I don't always have the energy. Anyhoo, I had no idea that kind of business information was available at the site. Perhaps after tax season I'll take a look.

If you go to the unofficial page, then get into the library, there is an article iin the Acoustic notes section on this. I think it is in volume 1 number 4.

Short version. First proto kluged together in late '66. They took a faceplate and crashed backstage @ Monterey Pops (June 16th -June 18th 1967)and pique'd some interest from the Doors and others. David Crosby and Paul Kantner heard the amps back in LA and also wanted amps. Apparently the first handmade amp was sold to Paul Kantner, "a few weeks later" which would have meant late July of '67. So it looks like THE first Acoustic was delivered sometime in July 1967.

About the same time, they were in contact the Doors producer and delivered the first 6 handmade 261 units to UC Santa Barbara, looks like August 5, 1967. (Since it would have been a little after Monterey, and the Doors chronological website confirms that concert on August 5th). Spent their last $350 on a van and gas to get the amps there, and were technically bankrupt before they even started.

Then the Doors liked the amps...the rest is history. By 1968 there were a dozen or so professional users listed on the 1968 catalog on the site.

Unfortunately, the story leaves off there, (to be continued) and newsletter Number 5 is not posted. Jumps to Number 6, and by then they were off and running on
other topics.

According to this, first amp was the 261, Looks like the first bass amp was the 360/361, there are schematics from these dated mid '68.

Hope this helps. It is a great read if you have the time.:bassist:

Wow thanks a bunch. I'll take a look at lunch.
 
So I got the new B200H yesterday, but it's doing the same thing the last one did, leading me to believe it's not a problem with the head. Could something else be causing the noise coming from the amp?

If it helps, it best way I can describe the sound is that it sounds like air is coming out of the speaker, and at the same time I can hear what sounds like an electrical current, and its really only noticeable when the gain or 5k knobs are turned up. Sorry if there is a really obvious answer to this, but I'm new to amps.
