Re similarities to the C502V, I’d be surprised if the basic compression algorithms weren’t just copy/pasted straight into this. What this has that the C502V doesn’t is, an extensive side chain shaping section, gain reduction range control, peak or RMS detection, and feedback or feed forward for any of the three modes, all of which can change the sound quite a bit obviously. The BM mode also has a fully variable knee, which can really hide the compression nicely.
Also, the THD and drive are not the standard PA add-ons, all of the DSP is from Bettermaker. The THD gives a subtle push, the drive circuit is a zener diode emulation which can be subtle or not. The drive knob maxes out at aggressive soft clipping, but the makeup gain from the compressor also feeds the drive circuit, so you can go well beyond that. With the makeup gain cranked the zeners explode beautifully, and keep the low end in tact longer than they should.
Super flexible and sounds awesome, definite keeper for me.
