Wow! Cool little amp. I found out about it from the crazy deal $119, free shipping, 12 packs of strings and a tuner... from Sam Ash. So... I got it a couple of nights ago. I played my band practice with it on Saturday. I played it through my compact 2x15 if some of you remember that. It sounded okay. But I was worried about using it in a real venue. So tonight I say, heck with it. It's small and I don't feel like lugging my Ampeg 212/SVT400t setup, and I know that my B100-R is not up to the task volumewise... Wow... It's a great little rig. I found myself turning down a bit because it really had more go than I initially thought it would. The tonal options are very simple, yet give a very wide variety of tonal options. I also like the built in compressor. I am not sure if a bassist who plays with a lot of highs would like it... But for me, I play heavy and finger style... I love good old school thumpin' and the compressor seemed to help keep the notes relatively equal volume. I turned the Low and Med Low to 2 oclock, the Med High to and High to ten oclock, enaged the contour and compression... and my 215 filled the room with plenty of thunder. Me like!!
