ok, been playing more with my FAB Distortion, and actually i;'ve found some nice sweet spots.
As a full out maxed distortion unit is sounds a bit fizzy, but turn the distortion knob down low and the level up high (level seems to effect the presence) and it gives a sweet crunchy overdrive sound.
Still not amazing but it's usuable!
Also got the FAB Metal pedal today...this ones fun! No where near as good as my boss metalzone for metal (cos it doesn't add any compression), but it gives a really nice fuzzy distortion for powerchords!
However, these are cheap pedals..the FAB metal 9v inout jack doesnt work properly, argh!
