I play a Fender Precision Bass with an EMG-P and a Fender Jazz Bass V with 2 EMG-J's. I am picky sometimes about my bass tone, but this amp helps me dial in the right tone for the right recording or song. This amp is not as quiet at high volumes since it has a MOSFET output, as I explained in the "Features" section. This amp can get a very gritty distortion if the gain is cranked up, but a pedal could help for the most part.
Overall Impression — 10
I play very many styles of music ranging from reggae to Slipknot-esque metal. This amp handles all of that perfectly, regardless of the cab you are driving it with. I have been playing for a good 5 years and would consider myself a tone-freak and love to build good solid tones. This amp has helped me greatly in finding my best bass tone. The on-board EQ has to be my favorite part, and I feel that it is missing nothing. I would definetly go for this head again if I lost it.
Reliability & Durability — 10
This amp, like every other Ampeg, is built like a tank and built to last forever. I take this thing to every show I play and I have had no problems whatsoever. A benefit of the MOSFET output is that I do not have to worry about replacing tubes so it is beneficial in many ways.
Features — 10
I purchased this head in the fall of 2007 so it is relatively new. This amp is the top of the line for bass heads, 450 Watts of pure power. This amp can be used for any style of music you could think of. From funk to heavy metal it will do the job perfectly. The only thing many players will consider that it is not all tube. That is not a problem since this amp features a MOSFET output which means it boosts the output signal but decreases the resistance which I immediately found impressive. Also included is one of my favorite features of any kind of amp is the on-board graphic EQ. I love to make tones and this EQ is very strong and helps shape the perfect tone.
