His clear, well balanced, deep bass.

SOUNDS

Perfect for acoustic guitars.

OVERALL OPINION

I use it for a month. The only negative is the lack of reverb, but when you see the difference in price with the 100 and 150, I prefer to buy the 90 and a reverb apart.
Value for money very good, I had a Marshall AS50 is the day and night!
I would do this choice without hesitation. Very high quality
