I'm considering getting one of these: http://pro-audio.musiciansfriend.com/product/reviews?base_pid=180069&page=2&sc=date&so=desc Mainly for my bass, into my amp, either an Acoustic B200 or a Behringer BX3000t/1X15 rig. I've never played a tube bass amp before and am intrigued by the claims of 'warming up' my tone with the tube. I have played guitar tube amps (I have two) and I also have one SS guitar amp (Fender) and I can honestly say the SS amp sounds as good to me as the two tube amps. I will say that I have played SS guitar amps that didn't sound as good as tube amps. I also like that this one has a built in compressor. I know, it's not the best compressor but money is tight and it may be enough. I've had a few compressors and got rid of them and have been playing without one. Okay, if I do this, would I be better off running bass/ART/amp's main input or should I run it in the effects loop? Okay, another thing I want to try is using it for the mics on our PA. If I do that, could I get away with running it in the board's effects loop? This is for practice/jamming only and right now we're only running vocals through the board. As I said before, money's an issue so if that will work, I can cover the two mics with one unit instead of having to buy one for each mic and then one for my bass. My thoughts are to try it on my bass, through my amp first, and, if I like it, decide whether I need the compressor it offers. If I don't need the compressor, I'll get one of the $29 ones for my bass and use this one for the PA/vocals. If I like the compressor on my bass, I'll get another of these. And I'm NOT looking to get over-driven sounds, just find out what this 'warm, tube sound' is. What do y'all think?
