JBL 7510A by FeatherAndTape
Requires either rev log pots or hard-wiring resistors in place of jumpers on the back of the machine to make useable for tracking due to its inherent gainy input.
Once this is figured out, expect a lively yet smokey preamp that fattens up drums, guitars, and certain vocals. It kind of bullies the details of the source--let's all the highs thru but not without pushing them around a bit first.
The gate sounds cool if you're trashing out a sound with gain, but on sources you want to sound like reality, disable it. You can also remove a leg of a resistor and rip an opamp out to iso the preamps from all the auto mixer and gate circuitry. It's not hard to work on and relatively cheap for the sound quality and learning experience.
The JBl / UREI 7510a combined with something clean like a Millenia or Sytek can get a lot of jobs done and teach you something in the meantime.
