I just bought the Boss GT6B effects board, and I am really happy with it!! I posted earlier in the Month that I was looking for advise, and you all helped out "Very Much". The effect takes time to learn, then play around with to tweek "your" sound into it....lots of headroom for creativity as well as keeping the basics "BASIC"...my playing style is that of a progressive edge, "Yes, ELP, Stanley Clark, Geddy Lee" to name a few, so having the true bit bypass as well as the multiple effects is a great plus to my rig. I run it through my rack mount sans amp DI and into a hartke head and it is sooooooo sweet!!! It is for me, worth the ($400.00) investment (IMHO). I can't wait to work with the midi extensions on it. One big plus too for me was the XLR outputs in stereo or mono!!! Bernie "The Tiger" Y.I.T.B.O.T.P.
