I've had a b100 for a year or so for use at Church. We move to the fellowship hall to play for the kids last night. It was just me, keyboards, vocal, and drummer with the wooden box thing. Pa was a fender portable ( the smaller one). Seems like I could not get any volume. I had gain at 10 o'clock, master at 1-2, sweep at 12-1, low at 10-11, low mid and hi mid at 2, and high 12... Seems like my buddies heathkit 120 water with a big old 2-12 cab put out more volume 20 years ago than my combo.

Is it me or just the nature of this little combo?

You're asking a lot from what I'd only consider a bedroom amp. I never play out with less than 450Watts for ANYTHING.

You may be the victim of crass marketing or unrealistic expectations - either way, Watt-up and remember that you will then have the option of turning DOWN the volume.

Still though --- Master Vol at 1-2 is pretty low on the Richter scale upon which I measure bass volume.

All settings were in clock positions. More at the 2 o'clock position. It was nice and bassey when I was next to. Just lost a lot as I moved away.

I guess I have not made the connection between what once was enough (120 watts 25 years ago with a 2-12 cab) is now considered a bedroom amp... Must have been the cabinet.

Maybe some day I'll have spending money to consider upgrading.

The ratings of the golden age were determined in a different 'formula' than how they are now. Look at the Acoustic amps of that time, rated conservatively but way more output than what was expected.

Any bass combo with a 12" will not do if it needs to fill a large room even a 15" combo has struggles, at least in my experience.
SurferJoe has made the point: live requires more power and an efficient cab to project the bass. Unless your in the realm of sound reinforcement i.e mic'ing of all instruments thru the P.A. You will need more powerful amp

I have used Hartke, Fender combos and hated them all due to the lack of full range tone at a proper room filling volume.
It's Bass, it needs to move alot of air and power to move that air.
Remember what may sound loud in your bedroom or living room will not compete with other instruments in a band setting.

I love my ACC gear. I have a variety of early 70's to early 80's amps and cabinets.

What's my number?

Here are some photos:

Any know of a good source for replacement pots for vintage ACC amps? :help:

The channel 2 mid range pot on my 320 stopped working last week. :crying: I think it needs to be replaced but I don't know where to find one or what to look for since I know pretty much nothing about electronics. This is my main workhorse for gigs and recording so I'd really like to get it fixed ASAP and keep it as close to original as possible.

Also, the mid range knob on my 370 hasn't worked since I've had it. As of now, this one's my backup so fixing it isn't as urgent but I would like to have it taken care of soon.

Any help would be greatly appreciated!
Thank you!

jj4001,

based on the schematic looks like 100K but definitely consult the tech guy nearest you

and This is where you need to be !

Thanks for the heads up, sturoc. I posted about it on the Acoustic site the other day but haven't gotten a response so I thought I'd try here. I did download the schematic so I'll print it out for my tech when I drop it off.

No sweat,
fyi: the Acoustic forum does not have alot of daily activity such as here. So some threads may sit for awhile before a response comes up.
I am currently having my 150B fully gone thru by a reputable tech. If it can be done easily gonna have him put a balanced direct out on it. This way I can retain some Acoustic character to the control room or FOH .
