OK, so here's the questions... I've spent a lot of time reading all the reviews on Ovnilab regarding compressors, and I've narrowed it down to 2 that I like. The MXR M87 Bass Compressor, and the Markbass Compressore. Some things I've noted are: The Markbass is a lot larger, has a 12V requirement (which is no problem for me) and of course has the tube for compression. The MXR is much smaller, requires only a 9V supply (which I can provide from my PP2+) and it has the LED readout. I have the pedalboard real estate for either, so size isn't an issue. Both pedals are +/- $10 of each other, so the price is comparable, both pedals are available at one of two GC's in my area, and both pedals have favorable reviews, both on Ovnilab, and elsewhere on the web. Has anyone actually A/B'd these two? Does one perform better? I'm not looking for deep squashing of my bass, I'm just looking to level things out a bit. Second question.... I play primarily 2 basses live, one is a MIA Standard P, the other is a Parts bass P, using Duncan quarter pound pickups, the Duncan equipped bass is A LOT louder than the other, so I've been using a MXR Micro Amp to bring the level of the stock bass up to match, this has proven to work quite well. My question is...Do I place the compressor before the Micro Amp, knowing full well it's going to be recieving distinctly different levels based one which bass I play, or do I place the compressor after the Micro Amp, where it will recieve a more uniform input level? Sorry for the long winded questions.
