    I'm trying to find out whether the JMP-1 preamp has special effects built in, but there isn't much info on that on the Internet. If yes, what effects does it come with?

    No, it's just a programmable preamp with an Fx loop.

    Definitely no built in FX. The effects unit that goes hand in hand with the JMP-1 is the JFX-1. It's also a rack mounted unit and they're unreal. None of the fancy unusable effects that you get with a lot of effects units. Just a good collection of very nice usable effects. From memory it even had an analog switching jack built in. This means you can program it to switch channels on a non midi amp. A very handy upgrade if you have an older amp.

    The only effect the JMP-1 has is female orgasm. They are seriously beastly sounding. I love the tone Megadeth got when they used it briefly in the 90's. Something about the way it handled the palm mutes is magic.
