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.

good value and battery life
Color: Purple
Love this!! the keyboard has a good life on it and charges pretty fast. I at first didn't really like that it detaches, but being able to hold the keyboard in my lap and type on the screen while I sit on the sofa is actually pretty nice. the trackpad does have a bit of a learning curve, but gestures/hotkeys are all listed on the bottom so it's easy to check whenever necessary. The material of the case itself also cleans really easy. I spilled a drink on it and it wiped right off. I feel like this is a pretty good value all things considered, especially when similar products at big box stores can eb a couple hudnred bucks. The only downside is that the keyboard, while slim, does add a bit of bulk to the case. It's not a huge deal for me, but my boyfriend who also has an ipad did notice the difference immediately.

Works
Color: Light Gray
Heavy! It is a nice case and the keyboard works good. Turns off randomly, but not too annoying. This case is heavy though! It at least triples the weight of my iPad, which is opposite the reason I got an iPad Air. Too late to return, I just take the keyboard out, but it must be the magnets in the case that are so heavy.

Fantastic keyboard!
Color: Navy Blue, Color: Navy Blue
Pleasantly surprised!! And less than half the price of an ipad folio keyboard - I know, one feels like one has to stay in brand. So I was nervous about buying a keyboard that wasn't made by Apple. But to be honest, the Apple keyboards and mice have betrayed me on numerous occasions. They have not earned my loyalty and need to reassess their dubious life choices. I needed a protective cover to stop my cats doom scrolling while I am asleep. I am OK with them using the internet - even though I have had random people text me back a picture of a large feline left nostril and just the letters WFT? It is what it is. I think they are little geniuses. But they scratch the ipad surface which is annoying. So I thought, what the heck - I am about to do my RN-BSN online and need a way to make my ipad transportable while protected, and set up so I can easily bang out some homework assignments on the run. Easy set up! What a relief! Tech usually hates me - sees me coming from a mile off and starts planning to at best ruin my day, and at worst have me calling my therapist. At first I started reading the instructions and my teeth hurt from the bad translation into English. But even with that negative energy I was able to set it up very quickly. Everything just WORKED!! I know. I set a low bar. These days one has to. This time I didn't need to. The cover is sturdy, soft and coffee resistant, thank goodness. The keyboard just plops on, connects through magic and immediately makes me feel like I am not as stupid as I thought! Absolutely recommend this wonderful keyboard - I dunno who do this voodoo but I am very excited. Crack on my lovelies! Make those dreams a reality.

Great product!
Color: Light Pink, Color: Light Pink
I really love this. The baby pink is so cute! I had my hesitations because I couldn’t see if the pink would be as good in real life. It’s like a soft blush color. Honestly, I was going to drop $350 on the Magic Keyboard for my iPad Air. Which is ridiculously expensive. This is a way better alternative. It fits my iPad pen. The iPad itself fits perfectly. I thought the keyboard was going to be tacky and cheap. But it’s pretty legit too. I love that when I’m done using the iPad, the whole case protects everything, even the keyboard inside and especially the camera lense. The magic key board does not have that feature. Like that it’s magnetic too. The material is so soft to touch. I can see how it can get dirty with ink spot if not careful. Overall, really happy with this purchase!

Sleek, Functional, and Feels Like a Laptop Replacement
Color: Navy Blue
I’m really impressed with this keyboard case. The magnetic attachment is strong and secure, and the keyboard connects quickly without any issues. The trackpad is smooth and responsive, which makes using the iPad feel almost like a laptop. The backlit keys are a great touch, especially with the different color options, and the lighting is even and easy on the eyes. The case itself feels well made and protective, and I like that it’s stain resistant because it stays looking clean. The navy blue color looks sleek and professional. It fits my iPad perfectly and doesn’t add unnecessary bulk. Battery life has also been solid so far. Overall, this is a great value for the quality and features you get. Highly recommend if you want a reliable keyboard case that’s both functional and stylish.
