I have the Tonelab SE and I really love it. I am glad you pushed to get your Expression pedals fixed, cuz this is the best real sounding wah in a modeler I have heard and I think I have tried them all. Also yes it can do metal fine, my fave cab is the AD412 for dirt and the bassman412 for clean. I really love the control asignability fnctn so you can add a pedal in for a solo. The treble boost pedal adds alot for cutting through on the metal settings. The A/B channel is great for really having 8 presets in front of you at once and For moderate crunch, the AC30 amp can't be beat. specially with some Irish Tours in a strat :D This thing is so real and tubey sounding it's great. Oh, and the boutique clean gives the fender mods a run for their money,although all are good. My only small problem is the Noise Reduction is a little weak. don't put it past 6.5 and you will still have sustain, but a little noise depending on your guitar. It's ace in the hole is the gritty breakup cleans and the blues and blues rock sounds. hope you like it as much as I have so far.
