I had used some of the Avalon preamps in the past for bass but looked around to see if there was something new/better on the Rig Exchange since I had to play bass this weekend and looking for new stuff on the RE is always fun.
I found a bass profile titled 'DRAGON' and it really worked well at home (playing to backing tracks) so used it today at church. Very, very nice...and got a lot of compliments about the tone/FOH sound. Surprisingly, it is just the amp in the profile...I didn't have a compressor or anything else on, but it has a nice natural compression in the amp itself.
Obviously, your mileage will vary (I have an Ibanez SR500 bass) but can definitely recommend!
