7 This unit went out of production few years ago, if it suits your needs it may be the best choice for you. 6 LXP-1 justifies the Lexicon quality. But if you want to go deep into it, there's a bunch of parameters to tweak with sysex. With a sysex editor everything is smooth. The manual is very good and detailed, every parameter is clearly defined.
Noise levels are very very very low.
The effects sound just great, can't say no more. If you need great reverb and also chorus and delay, this is the machine for you. Reverbs are full and clear, rich and deep. You get what you pay. I love it.
