Boss may not be synonymous with boutique tone, but this modification kit from Fromel Electronics will take your harsh, tubby CS-3 compressor and push it into new and much more desirable tonal territories.


The modification kit adds clarity to chords and presence to single note lines. With snappy pick attack and twangy, in-your-face sustain fueled licks, the CS-3 mod is like giving your tone a bear hug without suffocating it.


Included in this kit are detailed instructions, including photos, and all the parts to turn your CS-3 in to an incredible tone machine. No longer will your tone be weak, thin and full of hiss. Instead, these modifications add richness and
depth, increased headroom, better bass response and full body to the signal. The result is compression that sounds natural, clean and warm.

· 1n34a Germanium diodes replace the silicone diodes in the signal path producing a warmer tone

· Every capacitor in the signal path is replaced with high quality audio grade capacitors for better tone and less noise. Power supply caps are upgraded to allow the pedal to run a up to 18V for more clean headroom. 

· Capacitor values are corrected to produce a rich full tone, and noise free operation.

If you have basic soldering skills and can follow directions, this is an easy project. Don't pay hundreds of dollars for a boutique compressor when you can upgrade your CS-3 for far less.

NOTE: in 2017 Boss produces the some pedals with surface mount technology. This mod kit will not work on the new Boss pedals with a surface mount PCB. Review the image with this product listing for more information.

This is a kit to modify your pedal and there is no pedal included in this kit.

This works as a fancy oil cap remover. I wish my oil cap looked this nice.

Well built
Well made product. I have an volvo xc60 and it fits the oil filter housing perfectly but because of its thickness, there's some interference with the heat shield or it could be part of the skid plate assembly that is next to the filter housing.

Fast delivery and good quality part
Good quality snug fit. Works as should. Only issue I had was whe tightening oil cap back on the 18 ft-lb torque made this part slip. I used material to get a better grip and torqued slow but it still slip before the torque gauge read 18.5 No leaks! So it’s all good 😊
