I've had or used the following Boss products, some of them more than once as indicated:Originally Posted by Spudman
Overdrives etc: CS3, OD1, OD2R, OD3 (2x), OS2, BD2, SD1, MZ2 (don't ask)
Modulations: CE2 (x3), CE3, TR2
Delays: DM3, DD3 (x3)
Others: LS2, PSM5, TU12H, ME30 multi
The only references I've got are for the ODs I mentioned in the review. They all pretty much do what it says on the label except they don't quite respond quite like the individual pedals. I could go into (enormous) detail here, but won't. You have to hear them to get the slight differences. You can get those signature tones but don't assume you can just put the knobs where you would on the pedal for the same sound.
It is what it is, an effects box designed for use into an amp, NOT a POD competitor. The GT series are closer to that (and the ME-70 sits in the middle ground). The chorus is much like a CE series (more CE3 than CE2) and the trem doesn't have the wave knob you get on a TR2 (but sounds better IMO). The delays are digital delays rather like a Boss DD3 but with tap tempo and 2 seconds total.
I like the fact that I can feed the front end of my ersatz Fender (or Marshall) amp with something labeled Tube Screamer and get what I expected, which has not been my experience with multi effects in the past.
