Only the last fx in the chain will be stereo, so it comes down to the order you choose to put them in so its a matter of experimenting with the order until you get the sound in your head. Logically it would be mod, verb then delay but then i'd be tempted to try mod, delay and verb. In an recording environment is probably where the individual fx stereo outs would come into there own. The daft thing to do would be to feed a single input into a mixer, then feed three outputs into the seperate inputs of the fx and then feed the 3 stereo out puts into another mixer and feed the steroe output to seperate amps or stereo headblock which seems a good way to waste a lot of time and guarentee a headache lol.
Anyways Hammie bought the reverb fx today and very nice it is too, solid build, proper psu, switches are super smooth, the short/long mode is smart thinking, only downside is i would like centre notching of all the knobs as this would be useful in a dark environment where you want to make changes to yer verb sound quickly.
Set up 72 Gibson les paul, 50w plexi marshall, 120w 4x12 angled marshall greenbacks, Jen crybaby, Ibanez cs9 chorus, Boss HM-2 ( giving serious thought to changing that to one of the ht boost or drive or overdrive pedals.), blackstar reverb. Printed off the pdf suggested setting and tried them out, some very nice creamy tones were obtained, the valve in the blackstar seemed to act as another gain stage into the plexi so was getting great tones at relativley low volumes ( vol knob set to just under 2 ). Found that a sound that suited the front pickup didn't always sound so good on the back one but a bit of tweaking soon resolved that, so diffrent setting required for each choon depending on which pickup used, also founf that the verb smoothed out some of the squareness of the hm-2. All in all hammie would recommend it to anyone looking for geetar verb sounds lot of flexability with some judiscious knob twirling.
Here's a link to hammies my space where you can hear hammies forthcoming album of classic rock choons (no vocals yet there coming lol)
P.s Some blank pdf settings pages would be nice then i could add my own dots to the knobs for me own user presets, getting old and memory not to good lol
