Hi DNJ . I play predominantly contemporary gospel music . I don't play at excessively loud volumes but I do play to audiences every week of no less than 500-600 or more at church using just this amp . I have programmed my own backing tracks and played them and gone to the back of the autitorium to listen . I play in arranger style , solo piano/electric and organ . I play with live drummers and guitarist and singers . I sing in a group but don't put vocals through the amp simply because we have a great set up at church for vocals . But I don't trust anyone to hanfle my keyboard sound . I have programmed my sound and know what I need to hear . The sound through this amp is just incredible anywhere in the building .

O.k., in the light of day, I agree with just about all the comments above. Except that I tried it with and without sub and for my ears it needs the sub. Cutoff is 100 hz and there is bass below that point that needs to be heard.
However, I will experiment more both ways.
Tonight will be a better test--more people, a little more volume.

That's the beauty of it Don-with or without. The amp stand is great too.

I set it on top of the sub, and it's in a corner right behind me about four feet.

When you are short on space, that is fine but six or better lets you hear the "bloom" of the stereo to better let you hear what the audience hears.

I'm sure. I'm used to hearing a Bose L1 Compact in each ear! I will re-position tonight, and maybe use keyboard speakers for monitors as well.

I made a mistake earlier. The sub is 10". A real cheapie.

Just as good for this purpose. Just don't turn it up to much. A little goes a long way.

Hi Don,
Looks like a great little sub.
I am thinking of possibly adding one for my Bose L1 compact.
Question: does it have a built in crossover or do you need to use an external one?
Thanks
Eric
