I love the sound of a Leslie, but I'm on a tight budget, I drive a small car, and my back ain't what it used to be. I snagged a Line 6 MM4 awhile back and I've been using that for a Leslie, but the volume drop drives me crazy. A friend of mine offered me a hundred bucks and a Small Stone for it, so I took the cash and bought a used Boss rt-20 for $98.00. Normally, I steer clear of anything from Boss, but I figured since it was a stand alone effect, it would probably sound better than the MM4's Leslie- and it sounded pretty darn good in the store. I got the rt-20 a couple of days ago and since he hasn't picked up the MM4 yet, I've been A/B'n them. Other than the maddening volume drop, I think the MM4 actually sounds better. The rt-20's fast setting is pretty good, but the slow setting just kinda sounds like a Phaser to me. The drive, of course, is completely useless. I'm starting to think that I screwed up. Has any one else compared these two effects? Could anyone offer any good tips/ settings for the Boss? Thanks!
