This is a decent equalizer for the early 1980s. It does not muddy up the signal path like some other models from this era do, it has a couple neat displays on it, and the 12 bands are granular enough for basic tweaking.
It presents well. Each of the switches has its own LED, along with a few LED indicators on the bottom row. It has a VFD Spectrum Analyzer (those bouncing bars that dance with your music) which is a nice touch, as well as a reverberation depth display which looks really but will most likely never be on...
Oh, yeah. I'm sorry to say that this thing has a built in reverberation generator. This was a fairly popular effect to add to audio systems in the early 1980s and, in my opinion, it sounds absolutely terrible. If you want the shiny reverb lights to play along with your music (fair enough: they look neat), its best not to hook this equalizer up in the signal path. If you plan on actually using the equalizer as I do, I'm sorry, that display will probably remain off most of the time.
Build quality is solidly OK. The front plate is indeed aluminum, but fairly thin and painted black. Most of the buttons are plastic, though the bottom row is possibly aluminum. I hear that burnt out LEDs and bulbs are common for this unit, but I got mine in perfect working order from the Salvation Army. It's possible that you may luck out as well.
Note: if one LED is out, they'll all go out like a strand of Christmas lights.
I like that this unit has very low (16hz) and very high (32khz) adjusters. It's nice to be able to cut off these mostly unused frequencies that can muddy up the sound.
Overall, I'd recommend this EQ for its presentation and fair amount of usefulness. It pairs well with vintage audio gear. Definitely more professional EQs on the market these days, but this can satisfy basic needs and look good doing it.
