yep...i've seen those and have thought about snagging one. how's the bottom end on that? i'm not expecting or looking for much from an amp that size...just asking cos i wouldn't want it protesting too much and woofing out on a loud lower note.


I had one for a few years. As Thejohnny7band says, they are great for what they were designed for. The bass response is good for a guitar, weak for a bass. At a loud windy outdoor market, even a guitar might benefit from the louder stereo version with bigger speakers.

There is a 4x4" bass version too.

a battery type power supply is very quiet.
a transformer will create 60 cycle hum
so you probably won't ever know what the amp really sounds like.
maybe go with dry cell.

All amplifiers that you plug into the wall outlet run on transformer supplies. Do all your store bought amps hum so loudly that you can't hear the music?

Some modern amplifiers use switching power supplies that run directly from the rectified AC line voltage, however even they must use a transformer.

By the way, the batteries that go in that amplifier ARE called dry cells.

I didn't say you wouldn't hear the guitar.
I said that it would not sound as designed.

well I was indicating using a single battery to hear ththe amp
we used to call them dry cells,
to differentiate them from storage.

be that as it may
you still have the same problem
a Pure Dc circuit is not a rectified filtered AC circuit

ac rectified has ripple
pure DC dose not.

no need for you to be difficult.

By the way, where do you purchase a 60 volt single battery?

Incidentally, the amplifier doesn't know what is powering it as long as it has the required voltage and the required current. So it is going to sound exactly the same if the power specs are met, whether they be from a plug in supply or battery.

not only that but he must have taken electronics from Elmo on sesame street.

By they way you are correct in hard to find for a transformer. I did a fast search for a 45 VAC @ 2a transformer ( you need 45 volts AC to get really 60volts DC ( for Danes info) and I found one but they were out of stock.

Peavey used some Xfmrs that might work in their older low power guitar amps. I may even have one here in the store room.

I don't know why they called it a freedom amp. I had worked on a couple before and the battery life/cost was horrendous. I guess that if you were invested in a battery company it would be OK. They didn't sound too bad.

The freedom amp is a basic quasi complementary output circuit so there is really nothing special in it that would be costly to repair. (If memory serves me)

one of the older (larger) ones? i recently sold my older one for $150. hadn't used it yrs. good luck, dane.... even if it's a newer smaller model that'd be a good return on the $25 ya have in the amp.
