I currently split my signal (after compression) into an OC-3 which heads to a bass amp. However, it is a rather synthetic sound (heavily reliant on having a decent bass amp with EQ etc to obtain a decent faux bass sound) and also - at times - it warbles appalling even in Polyphonic mode.

That said, mostly it is quite reasonable. Another gripe is the sustain is rather short, I'm actually pondering another mini compressor AFTER it to smooth out the volume discrepancies between my guitars E, A and D strings and to increase the sustain.
Before I do, I have heard the PS-5 is BETTER?

How about the PS-6?
..and even the MO pedal...
Anyone have experience with these or others?
Thanks!
