hold on to it, cause seems they've decided to cease the SRH505 model out from the market this year (the 4 string SRH500 is still available though). My SRH505 has become my favorite too. Great sounding bass. If you were aiming to get the SRH505F, luckily they are still on this year catalog. I'd get it ASAP if I were you. Don't know how long they're gonna be available.
