The MPX 100 is a true stereo dual-channel procesor with 24-bit internal processing, 20-bit A/DD/A and S/PDIF digital output. Powered by a new version of Lexiconʼs proprietary Lexichip,™ the MPX 100 has 240 presets with classic, true stereo reverb programs such as Ambience, Plate, Chamber and Inverse, as well as Tremolo, Rotary, Chorus, Flange, Pitch, Detune, 5.7 second Delay and Echo. Dualchannel processing gives you completely independent effects on the left and right channels.

This is what I say: Yes, I was really happy with this unit which I bought, with its original power supply, on Ebay, about 6 months ago, except the connection was slightly dodgy, and the unit would flash at me without working properly. I returned it to the seller who told me he could fix it. He did, but a few weeks ago the problem returned, and I haven’t got the patience to get this sorted, mainly because I simply don’t need the unit anymore. If you have the patience and can fix it, you’ll have some classic Lexicon sounds.

The other issue the machine has, is that the Program knob isn’t the original. I knew this when I bought it. So, when I first used it (once the power supply issue had been fixed) whist the button might have been pointing to “Tremolo, Rotary” for example, what it was actually giving me was “Delay Echo”. I lived with this for a few days, but it was so super-annoying, I did a DIY job with some masking tape and a pen. Please see the pictures. Yes, it looks pretty rubbish, but at least it’s now pointing to the right setting! If you can live with this, and you can sort out the power supply issue, you will have yourself a bargain, I’m sure.

The unit's depth, only 10cmm, I found really useful when the machine was part of my home studio.

Thanks for looking, and bidding if you wish to.
