I recently got the chance to play a 4001 (first encounter) at a local music store (it was used.) The sound was very thin and had no low end at all. Is this common? Geddy Lee and Chris Squire's sounds have a huge midrange punch, but the low is there too. Does it require a lot of work to get a good sound out of a Rick? Was this an uncommon bass? I am not bashing in anyway- I think they are cool basses!
