Dunno about the Orange Squash, but I just got a BBE Opto Comp this weekend and it's superb. Solid case, true bypass, good control range - construction is basically boutique-style. It's my second BBE pedal, after my Freq Boost, and I'm very happy with both. They did the basic interface things right. If it's an Orange Squeezer clone, it'll sound like an Orange Squeezer, which is colored but classic. But I'm sure the construction quality is nice, at least.
I didn't think GC sold the Orange Squash as part of the blowout, those were the pedals I was referring to. Unless they have had a recent sale on the OS. I don't know why they'd discontinue the OS, it's a great comp.
