The J. Everman is very nice, The Fulltone is nice, too.

But if you want the BEST Octavia clone, then get the Prescription Elec. Expereince. Among the studio musicians it is considered the closest to a Tychobrahe.

Ron Sound octave is just as good, if not better than the Exp.

For clean octave, Prescription Electronics makes the C.O.B.(clean octave boost)
