REVIEW: Monte Allums Boss CS-3 Mod



This is a review for the Monte Allums CS-3 Opto Mod Plus.
cs3modMany claim the Boss CS-3 is a great sounding compressor just as stock. Well, I admit is is not bad…but great? I must respectfully disagree. But then again, I’m no Stevie Ray either so perhaps more talent than I possess is required to make this baby sing. Being that as it may, I just was not impressed with the CS-3 out of the box.

It was my experience with the Monte Allums SD-1 mod that led me to pimp the pedal. After receiving my brand new CS-3 in the mail and using it for a few weeks, I went ahead and put the pedal under the knife once my kit from Monte arrived.

Instantly, I saw why this mod was so highly recommended. The crispness of the compression just floored me, and the sustain was like riding a perfect wave ( putting knob at 12 noon sounded just perfect for me ). A very, very natural sound comes from it now.

The mod even goes so far as to replace the stock on board amp with RC4558P and Burr Brown OPA2134PA Chips. This is done to fix the infamous noise problem, and I can tell you from experience that this does indeed do the trick. You get a clean overdrive signal, and nothing else. Well, unless you pump it into an overdrive and crank it up…but that’s to be expected because now you’re technically simulating distortion.

After this mod, I rarely if ever turned my new CS-3 off just because it made such a fantastic sound. Combine this with a modified SD-1 Overdrive, and you may well have all the pedals you’ll need for most of your jamming. Considering the sorry state of the stock CS-3, BOSS should hire Monte as a technical consultant!

One of my guitar instructors, who is not a Boss fan by any means, was floored when I brought this into my lessons. He didn’t think such a thing was possible for this pedal, even though he had heard about the mod.

The Opto Mod Plus in my opinion, can get no less than a 5 feathers out of 5, for taking something rather vanilla and making it sound so freaking fantastic.

5 Feathers out of 5.
