I’m selling my Line 6 MM4 that I got Jack Vaughn (jvh3.com) to mod for me. He did his “hi-fi mod” that is basically the Keeley mod. It includes cap upgrades, new input and output buffers (via new Burr Brown op-amps), and decreasing the resistance within said buffer circuit to eliminate the infamous volume drop associated with DL4s/MM4s, as well as trading out the stock LEDs. Got him to put in blue LEDs to match the unit. Jack is the real deal and did a great job with this pedal.

It’s in good condition with a little wear and sounds great. I really wish I could keep it, but it doesn’t make sense to keep while I’m looking for something different.

It comes with original box, manual and power supply. $200 plus shipping.
