its a road case for the space echo.. he only used the Re-301 on stage, except for
like what Web said.
The Re-301 has a spring reverb on it and while he says he doesnt use it, I've seen
close ups at some shows with straycats first reunion and the 'verb knob is slightly
on (this equates to "ambience" not surfs-up sounds)
ps. yes web, an external fender tank ( tube spring reverb) affects the signal path
but Setzer has an AB box on that tank when he uses it, so he can switch it in and out
at will (smart fella that setzer).
