Don't like to play without it

By TourMan999

The problem with most acoustic amps is that acoustic guitar top strings come out sounding really like tin. I have found that the "noise" this unit can generate is due to the power supply and grounding. I have plugged this unit into a boss tuner 2nd port and got the noise sometimes. When I plug this unit into its own power supply and on a separate circuit from what my amp is plugged into I get almost no noise at all. (not an easy chore in most gig situations to have separate circuits). Each gig I do with this unit is different, sometimes I plug it in and get no noise, sometimes I have to mess around with the power supply and what outlet it is plugged into for quite awhile to make sure there is no noise.(a hum, when I play you can't really hear it, but when your not playing you can sometimes)This unit by itself still did not satisfy me in the sound totally, to really reproduce the sound of an acoustic guitar. I use the BOSS EQ20 twin pedal with this unit, and finally got the my guitar to sound as rich as it does with no amp. The AD5 unit and the EQ20 unit together is really dynamite for me.I have had lots of people comment after a gig that my acoustic guitar really sounded great (a martin d45 w/thinline pickup).The only thing I do not like about this unit is that is does not have the option to use batteries like everything else.I use a crate battery operated amp, and I can put batteries in the EQ20 and tuner but not the AD5 which is a real drag. The EQ20 twin pedal by itself almost works as good as this unit, but the AD5 adds some other tones that I can't get out of the AD5.

I borrowed one from my brother a couple of months ago. I have to give it back now because I am getting too spoiled! I play a Martin D-15 with a Baggs I-Beam Active and it sounds pretty good all by itself. The other day a guy at church asked me if I had done something to my guitar because it sounded so good. This isn't a guy I would think of as someone who would notice anything subtle (about anything). It is like playing a great guitar in a great room with nothing in it.


Excellent even in 2016

By Dan

from Tampa

This preamp provides very good eq, body and mic effect processing, and reverb and chorus. Mono or stereo out with balanced or balanced lines to amp or powered speaker or mixer. Very compact. Designed for magnetic and piezo pickups and has two inputs. Great even by 2016 standards imho. Picked mine up used and am very pleased

It takes some time getting used to, but it is well worth it.


Boss AD-5

By Ray O. Hope

from Martinsburg, WV

This product is simply "awesome"! I bought it with BIG hopes, and I was not disappointed. The sound clips from the Boss website were a true representation of what this box can produce. It was money well spent, and I'd recommend it to anyone who's looking to spice up their acoustic tone.


lots of features, easy to operate

If you purchase the optional ADS56 Clamp Set, the controls are easy to adjust (I highly recommend getting the Clamp Set).


Good, but not Great...

By Musicman1-jMSlZ

from Lampasas, TX

Definitely helps warm up the piezo pickup. Little more white noise than I wish...


it's ok

By guitar john

As I've read elsewhere, there is a bit of noise in this unit. It's best as a direct box. I can adjust it for a long time, and then hit the bypass button and prefer the sound of no effects. So what are you adding to your accoustic sound? Well, you are adding an electronic fx/feel. If you want that, why play acoustic? I used two pickups with this unit - the Fishman Piezo was the good one with decent results. If you use a Dean Markley sound hole coil pickup, don't buy this unit - buzz city. I was even thinking of clipping a grounding line on the 1/4" jack to try to case the buzz out. Otherwise, I think only top quality pickups may help the situation. Here's another idea, get a little mixer with fx's and use that in place of this unit. Maybe I'll try that next.
