the RV-3, DD-3, AD-9 and VFE phaser are still fetching a good price if you' re selling
the MXR is of course a classic, what's the VH pedal next to it ?
that Viper, sinceT-Rex went under, the pedals were blown out and are now sold out everywhere, might be worth something one day
but it's not about $
you can make a nice timee/modulation board with those pedals,
my pick would be the DD-3,AD-9, RV-3, Viper, VFE, Digitech CF-7 and ToneLok CF7
hmmm, already 7 pedals but that would cover all my modulation/verb/delay needs
