JBL/Urei 7110: Urei is famous for their 1176LN, LA2A, and other vintage classic studio compressors; for a while in the 1980's, the brand was owned and manufactured by JBL. The JBL 7110, a mono line-level rack unit, is supposedly based on the Urei LA10; there were also stereo versions, the Urei LA12 and JBL 7112. People disagree about whether the Urei-branded and JBL-branded units are really the same.
 
This one is a single mono channel in one rack unit. It has both balanced and unbalanced inputs, by 1/4", XLR, and barrier strip. However it is only designed for line-level input, it will not operate well with your instrument plugged straight in.
 
It is a fantastic comp for bass, with a big full low end, a smooth warm sound, and low noise. It has one unique feature, a knob to pan between two different modes of compression: peak and average. It's hard to put into words how this works or sounds, but different settings can act/sound more like an optical comp, or more like a VCA comp, and there can be a subtle EQ-like effect as certain frequencies are compressed differently as you pan between the two modes. Unfortunately, setting the knob to 2:00 or higher (towards the peak mode) results in a lot of buzzy clipping on a strong bass signal; but that still leaves enough knob-turn to work with for audible variety. The action is capable of being very punchy or very smooth.
