Hey, you guys. I hope I'm not breaking any rules here in asking this, but what do you think my 470 might fetch on the open market? It works perfectly fine, has the original vinyl cover, and sounds great through a JBL 15 in a TL cab. I'm thinking about thinning the herd. :^)

Well, there's this one that sold here in January 2016. If you search Ebay you'll find three that sold recently, two for pretty decent money and one bargain because it hadn't been tested and verified problem-free. None of those appeared to have the original footswitch.

You might also check in at the unofficial Acoustic forum... bunch'a blame phanatics over there, probably a good place to pass through.

Yeah, there are definitely deals to be had -- I know, I've been bottom fishing for years. LOL I guess I've set my expectations from watching them come and go on Ebay over the years in the $300-$500 range plus shipping even without the footswitch.

Maybe I'm inflating the value because I'm biased. Even though I love the 270/370 amps, my opinion is that the 320/330 was the best of all the Acoustic amp heads (runner ups: 220/230 & 450/470). I'm also pretty much a purist, so the original footswitch is a must-have for me and worth a premium. Every once in a while a 320 footswitch will pop up for sale, but never right when you're looking for one. A 320 FS could probably go for at least $65 by itself if not more.

I know it would probably take at least as much as he's asking for me to let go of my 320 w/original FS. If I overprice it, then the worst that could happen would be that I'd be stuck with it. Oh-no!!! That said, I do realize that part of the appeal of vintage Acoustic amps is bang for the buck, so there's that.

Bought my prize 320 head in this very room a few months back for $300 in from what I can see, equal condition to the one in the ad. So all the discussion above has more evidence to add. A pedal isn't really on my must-have list as I'm not much for floor controls lately.
So subtracting an over-priced pedal leaves a market-value price for the head.
What at first seemed steep only looks so to someone not enamored with the original pedal.

As you know, the footswitch isn't really a necessity, but it does unlock an extra bit of switching capability in the 320 and 330. Here's a link to an old post of mine on the unofficialacousticcorp message board where I was helping someone troubleshoot an issue and described how the switching logic works both with and without the footswitch.

Acoustic 320 A or A + B combined switch diagnosis

The logic in the 330 is identical.

My 320 makes me happiest when I use the combined input and create 'separation' by using the rotary eq controls to emphasize highs in chan A, lows in B (I also use the graphic on B, setting in photo).

I then optimize the sound to my liking on each channel separately then combine to taste by using the two individual volume controls.

It's freaky how much separation this creates and reminds me tonally of the active crossover systems I've used in the past.

I just wish there was a master volume that could control both channels once both have been set.

I love the 470. That was my first experience with Acoustic years ago and it still delivers.

Right, using it like that the footswitch isn't going to buy you anything new. The pedal mainly comes in handy for temporary changes, i.e. boosting the volume, highs, mids or lows when combining channels or for switching channels altogether for two entirely different sounds. On the holy grail 330 the footswitch also lets you kick-in grit/distortion with the master volume control.

That really would be cool. On the 330 the master volume is only assigned to one preamp channel at a time, not a blend of both A & B like you're suggesting. Getting the channels blended just right takes some work.

To me the master volume is the bass guitar volume. I do my channel mix typically with the instrument at 50-75%.
That's my headroom. That way my blend stays put.

Does the 470 go down to 2 ohm? I'd love to run one with two of those old JBL loaded 215's

From the owner's manual:

"Any impedance between 2 ohms and 4 ohms will give optimum results; that is, 170 Watts RMS. 4 ohms is the best match because with a 4-ohm load, the amplifier runs slightly cooler."


I've been told that the power supply was designed to sag in such a way that kept the output power roughly constant with 2 or 4 ohms.
