Erm, well, I was never going to sell this piece of gear, but... I ordered and received this from Jack when he had the design complete - Purity preamps were very much a work in progress. That having been said, this unit does not have the 120/240 VAC PSU. BUT it has audiophile / studio grade component in every spot Jack offered one - at a premium, of course! Linkage: Talkbass reviews Jack Read himself giving the 'inside scoop' Pros: * tone, tone, tone. I've a Mark Bass LMK and the Glockenklang Bass Art Classic and had the Demeter HBP-1. None of these can beat Read for tone. * it's a small and rugged unit. No printed circuit boards, just professional-grade point-to-point soldering. * can be serviced by a pro! Cons: * relatively unknown * 1 input * no bass cut in fx loop 500 quid - Pounds Sterling - including an SKB 2U case. Also a trade I'd consider: Kasha Rockmod II or III.
