I wanted to add to the tonal spectrum of my E530, so I decided to get a rack EQ to go with it. I was already using the Boss GE7 and EQ20 with it but I wanted something to fill up that 1u space n my rack. I bought DOD SR430QX. Great EQ unit. So far I've found nothing wrong with it. I read some reviews before buying it that mentioned how the unit is noisy and what not, I didn't find i to be noisy. I think for $100, this unit delivers and does what its meant to do. Its Stereo 15-band EQ. 2 channels with 15 bands per channel. with 2/3 octave controls. -12dB boost/cut per band and input control w/LED meters. Balanced XLR and 1/4" inputs and outputs. Low cut filter at 50Hz with a 12dB/Octave Slope. 20mm faders. Without further verbal bullshit, here are the pics: All set in the rack and good to go! Some pictures with my JVM & 1936 cab.
