Roland AC-90
A transistor
2 x 45 watts power, but small watts
rglages and connectivity standard


Config simple, sounds pretty hollow, the same AC60 ... a little more powerful ...


Bof ...


I've used for 6 months, then sold for a AER Compact 60 ... see anything ... this is not the same price, but the EAR is trs trs far above, and despite its much more powerful 30 watts less on paper!

See Roland site ...
Moult connection ...

Full of possibilities that I explain the Flem! It is very well thought out.
We just put it on one foot, it's pretty rare.


All things


So voila, 2x45W announced the return is a bit limited but it makes him (the AC-60 really has to be just right ...)
The sound is the Roland Hifi trs, we like it or not

The trick is pretty key to SHAPE the gre mdiums almost as if the coup taient paramtriques it will always be some type of microphone (piezo, magnetic or condo) have a good sound. The versatility dtriment of excellence ...
We regret that price even when real mdiums parameter.

The chorus has a stro quite impressive but cradent just the sound of scratching your ... indispensable Footswitch
The reverb is very well.
The delay sucks.


If you are looking for 700 the best guitar sound possible, go your way and type in or AER Ashdown.
If you are looking for a mini portable and versatile sound of singing, guitar or other and have a good sound, this is for you ...

Good business opportunity or in the promotion abroad of around 550/600. Nine in France is expensive ca ...

See Roland site, nothing to reproach him. Pushing a little, we regret the absence of effects loop, but good for the reverb and chorus are very good, which makes the loop a bit outdated.
What I like is the direct output tuner and the ability to control the mute by a footswitch. And also a antilarsen with automatic or manual, works well.
Another strong point is the ability to plug the guitar in stereo for those who have a guitar with piezo + mic and XLR stereo output (2 XLR) for the console.
It can be mounted on a stand or tilt it back.
Delivered in a padded case.


Yes, good sound, easy, it's what an amp!


Neutral to my ears, I had good compliments through the Roland AC-90 connected to the output console.
A large volume (50% of past master) is a little more "tough." I would say between 30% and 50% of the master it produces the best sound. I play a Seagull Mosaic equipped with LR Baggs Duet ibeam, dual source, the sound is faithful and clear.
Power level is entirely satisfactory, provided they do not expect to make a room without passing on the console. In a small bar that does.
I am amazed at the power in comparison with the AER Compact 60. I tried and I'm sorry but the 2 woofer Roland makes the difference is greater and more progressive while the compact 60 gives strong input.


Not much to blame him, I'm surprised he is not better side.
A versatile amp with good sound, true, I read somewhere Hifi, but that's what we demand an amp sound, connections, powerful enough for small cars and stereo XLR DI by transplanting for more large. Very good reverb, chorus and delay correct, but I do not use, antilarsen manual or auto, can mix different from 2 sources (piezo + mic the guitar) or connect a microphone singing ...
