The EBS multicomp may be nice and all, but its considered subtle as a compressor. I'm looking at you asking to replace your Dynacomp, which is known for its extreme 'squishy-ness'. I don't really have an answer, but I'd still recommend the BBE Opto Stomp and Aphex Punch Factory since they are cheaper and do pretty much the same thing as the EBS.
reyrey: haven't tried the kingston before .. i should you know .. hahah .. i think the finish of the zephyr basses are okay,not fantastic but the burl maple top kinda drew me to it .. hahaha .. it was a nice yellowish-orangey satin finish ..
that's great man .. good to know you have a good bass .. post some clips of it recording soon .. =)
