Marshall JMP-1 Tube MIDI Guitar Preamp

Sound Quality

I used a charvel model 375(?). At first it sounded very marshally. Then the more I used it and the more setups I tried to put it with the more sterile and one dimensional it began sounding. I tried plugging it in to a 2x12 cab with V30s in it via a solid state power amp. Yes, I agree that a tube power amp would probably sound better, but I don't have one and Marshall wouldn't say, "Hey this preamp sounds great if you amplify it with a tube amp." No, they would say that it sounds great in all situations. Well in that situation every tube combo I had blew it away! Then I tried it in fx loops of my various amps. Sounds shitty. Lastly, I tried it direct into the board and mixed it with my favorite pre-recorded band cd. Again, nothing but flat, sterile sounds. This became more apparent when I recorded a track using my pod 2.0. The pod sounds a lot more round and realistic even though it, too, sounds a bit artificial to me at times. The marshall jmp-1 began to remind me, as the night went on, of my boss guitar driver which, I believe, is a rack mountable compilation of various boss od or dist pedals. Very solid state sounding when plugged in direct. Quite a drag. I was looking forward to a single rack space with lots of marshall goodies. Alas, if it seems to good to be true...



General Comments

I've been playing since 1976. Yeah, that's 25 years. I've owned lots of different amps and preamps. Some good some bad. Some ss some tube. In searching for the tone of a lifetime occasionally I've been suckered into trying/buying things that sometimes common sense says won't work. As a result I tried ADA MP-1. Liked it lots until one day I happend to plug into a real tube combo. WOW! The sound was much more honest, immediate, warm, round, real, and natural. So, I tried a few amps, gigged with 'em then got tired of gigging with idiots, quit gigging and just taught for the last 5 years. In that time I got hooked on the pod concept. Bought one and the DG Stomp. Then plugged into a real amp again. Suffice to say that nothing beats the real thing!! Fortunately, I won't eat the jmp-1. I have another 2 days in which to return it. It goes back tomorrow. Finally, I would like to say that my comments only reflect my opinion. I'm not saying that this is a bad unit. It just didn't work for my ears and sensibilities. I'm sure that there are plenty of people out there that, with their gear, experience, and personality can make great sounds with it. It just aint for me. Viva la difference!!
