Red Rocket - the best source for photos of Acoustics is in the Acoustic forum, under the thread "Look At The Rigs".
The 2 best features about the 450 (which is my main gigging amp in one band) is 1) the distortion circuit and 2) the EQ sliders. It was designed for both guitar and bass, so the last 2 EQ bands are very high - 1100 and 2200 I believe. When used for bass, especially with the Lead switch on, you get some very interesting harmonic and overtone content in your bass sound if you crank those sliders, and an interesting deletion if you drop them. And nothing else in the world sounds like that distortion. Just my 2ยข. 450 + 106 is def a winning combination.
