[quote="Dietmar"]this is just out of memory - but I'll check if it's correct:

thanks dietmar
yeah apparently sting had one of these in his inventory (tour booklet 1982 states as much) but the phaser doesn't produce that effect. the phase 90 produces that 'swooshy' sound you can hear in very early police sets during some guitar solos and perhaps 'truth hits' but we're talking just the first half of the outlandos tour at that. it wasn't used much after that.
the effect i've referred to (and which the sample demonstrates) is an envelope filter effect of some sort - similar to that used for andy's guitar in 'hole in my life' - otherwise called an 'auto wah'. i just don't know if sting used the same pedal as andy (mutron III) - i hope not because they are expensive, and the clone (Neutron) is hard to make. I am betting it's some kind of auto wah kinda pedal for bass but have no idea which one.
