I'm preaching to the choir too but Friday night was my first gig with my STL 900 and wow! what a great tone. The drummer and guitarist were both very pleased with my huge, punchy, cutting tone. A few friends were in the audience and they all said that the bass sounded great and punchy. I was playing it through 2 Avatar Neo 210s and I felt it moving my pant legs at times. The band leader even took me out of the FOH because he felt like it wasn't needed. What a great amp.
I didn't have a gig bag for the amp so I went out and found a great backpack style laptop bag that fits it perfectly. It came with a special slightly padded cover that the amp fits in nicely and the inside pocket is ideal. It also carries all my cords, pedals, and whatnot. I'll find a link to post because it really is perfect.
Also, yesterday I used my Boss ODB Overdrive pedal and the tones I was getting out of that were really sweet too. If overdrive can even be called grindy, dirty AND smooth this would be it.
Yeah, as I said, most of you already know all this stuff and I'm late to the party but it doesn't mean the party's over. In fact it seems like it's just beginning!
