The sovteks should sound good, let me know what you think of them. I can vouch for a Quadverb, been using one in my live rig for years. I posted the settings I use with my standard MP2 patches (light stereo delay and a bit of chamber reverb), I find this quite usable for a variety of sounds. I used to use a nice long delay for solos but seem to have lost it over time.
Do you have a CC expression pedal you can assign to the stereo master (this can only be accessed by CC), I mostly use the one patch and use the pedal to turn it up for solos, also very handy at the end of songs etc to turn the volume off, though I could use the tuner mute on the Quadswitch.
