I have developed a beautiful sound, perfect to play the volume-swell intensive "Cathedral" by van halen through the Spider IV amps. the settings are as follows:
Red metal
Drive: half way
bass: half way
mid: 2 o' clock
treble: 4 o' clock
chan vol: full
no fx 1
no fx 2
fx 3: Digital delay, routing: post, tap: Don't ctrl, time: 20ms, fdbk: 20%, bass: 57%, treble: 46%, mix: 40%
enjoy! Tabs for "Cathedral" are of course on the internet.
