Acoustic Guitar Community

Welcome to the Acoustic Guitar Community.

I picked up a new 'used' Roland AC-60 acoustic amp over the weekend. The Amp was in excellant condition. Absolutly flawless for less than half of retail + tax. :)


My Godin content here is that I wanted to play my Seagull S6 thru it, and also me able to amplify vocals.


Unfortunately, the battery for the B-Band aftermarket pickup in my Seagull is dead. The battery holder isthe older style B-Band type, not the newer 'pouch' type. Anybody have any experience replacing batterys in the B-Band systems?


Otherwise, the Roland AC-60 is wounderful. My 5th Ave sounds freat played thru it. Just trying to get the Seagull electrified again.

Cool find!  As you may know/remember, I have a Roland AC-90, and play my Seagull Performer and my 5th Avenue Kingpin II through it.  Have fun!

No knowledge of B-Band battery systems, I'm afraid - but I guess it's a bit of a PITA...?

BTW, if anyone's interested, Wolfe Guitars has a used AC-90 in their TN store:


Ah, got the B-Band battery replaced. I can see why they went to a new design battery holder. The Seagull sounds amazing thru theAC-60. Now to research vocal mics... Suggestions?

I have a Shure SM-58, and I like it. I am no high-tech audiophile, however... ;-)

Ithink the SM-58 is a good default purchase. Have to save up my allowance.:)

@ David ... Earlier. when I asked the microphone question the overwhelming consensus was the Shure M-57 or M-58 ...

Your first mic required power from where it plugs in - "phantom power" - to operate.  I believe the Roland has jacks for both types...

Microphones come in two general flavors: condenser and dynamic. Condenser mics are mostly used in studio/recording applications and require additional power to work (i.e. "phantom power"). They can be thought of as "active" in the same way active guitar pickups require a battery to work. Some amps have this required phantom power built into them, others do not, thus necessitating an external phantom power supply. Dynamic mics, on the other hand, are passive in that they do not require any additional power to operate. Condenser mics are much more sensitive than dynamic mics which is why they're mostly used in recording applications. Dynamic mics are usually quite rugged and not nearly as sensitive, thus their favorability in live applications. Dynamic mics are also less expensive. Now, this isn't gospel. There are plenty of instances where condenser mics are used in live applications (a la traditional bluegrass bands whose members all crowd around a single mic) and dynamic mics used in the recording studio (the Shure SM-57 is great for recording electric guitar amplifiers). But, generally, I think you'll find the above to be be true 75%-85% of the time.

The Shure SM-58 and SM-57 are two of the most widely used and popular dynamic mics on the market. They are extremely rugged and sound very good. They're fairly cheap and can be found everywhere. Their internal workings are almost identical, but the 58 is specifically designed to maximize vocal reproduction whereas the 57 is more general is its applicability, although it's mostly used for amplifying instruments.

In summary, both mics are good to own. They'll last forever, always sound good, and retain their value.

Hope this helps!

It's always nice when someone knows all the details... :-)

Now we all do!  Thanks, Jason!

I just re-read my post...good lord I'm long-winded! Glad someone appreciates it, though!

Hmm, very strange. I've never run into a dynamic mic that required phantom power. My understanding is that dynamic mics consist of a coil attached to a diaphragm which is suspended in a magnetic field generated by a permanent magnet. This results in an entirely passive circuit, which requires no external power. When sung into, the diaphragm vibrates, in turn vibrating the coil thus creating electric current and ultimately resulting in amplified sound. I'm certainly no expert, though. In any case, glad the 58 worked out. Some people don't like the SM58, but I've been happy with mine.

Actully this clears up some of the questions I had about mics. I was sort of thinking about an SM58....  Great post Jason.
