the highest numbered old-style cp251 i have is 1224, and the lowest numbered new one is 1282. the easiest way to find out is to ask the vendor to open the box. if it has red jacks, it's an old one. if they are all black, it's a new one. also, the attenuators on the old ones are labeled "0 - 10" and on the new ones "-5 - +5". i'm pretty sure analogue haven is all out of the old ones now since that's where i got mine.The Alison Project wrote: The reversing attenuators is a big plus for me, and I plan to buy two CP-251's very soon.
Does anyone know the serial numbers they start at or a way to tell which version you are getting by the box cause I will have to order these online, and don't want to get someone's older stock??
but the best option is to ask the vendor to check. any vendor who won't check this for you is someone you don't want to buy from anyway.
