Ok, here's the deal: I'm in the process of assembling a pedalboard. I got the extra large, extra wide model from Rondomusic.net, which is 29 1/2" long by 15 3/4" wide by 5 1/2" deep. Right now I have a Boss ME50B, which I dig a lot, and a Boss DS-1, which sucks all the low end out of a bass. I'm going to use the DS-1 in conjunction with a flanger or sub-octave to experiment with some wacky synth sounds. I also have a Russian Big Muff Pi on the way. I play in a hardcore/metal band with pretty much two levels of dynamics: really loud, and really, really loud, and at my church, where the volume is, ahem, a bit more subdued. With both my band and at church, I try to get a variety of sounds to make things more interesting (hence the multiple effects and pedals). My amp (Kustom Groove 1200) nicely covers all the volume requirements My problem arises when I use the different effects. My overall volume often rises (with the flanger or phaser on the ME50B) or drops (with the DS-1). I know that a compressor will help me out quite a bit, but I'm having a hard time figuring out which one will work best for me. Most of the pedals that I'm seeing are either too noisy (Boss and digitech) or don't offer enough tweaking to be useful for my range of music (BBE). I've been researching the Alesis Nanocompressor and the ART Levelar, and both seem like they might work. I've read that the ART sounds excellent for bass, which is cool, but I'm not sold on it actually working the way I need it to. The Alesis seems like it would work great for me, but I read that it doesn't sound so great for bass alone, that it's more of a PA compressor. HELP!!! Whatever I get will be mounted last on my pedalboard so that it will be compressing the final signal that will go through my BBE Sonic Maximizer into my amp. I can use whatever suggestions you give me.
