The Volume control acts as one would expect. The TBX has an indent at 5 which is a neutral setting. Turn clockwise and the pickups get more “sparkly” (like a presence control on an amp), counter clockwise and they become more muted a bit more like humbuckers. The effects are subtle but work well when you get the hang of it. The Tone control is interesting and really works as a signal blender. Set to 0 it only lets the sound from TBX and Volume out which I shall call “clean”. Set to 10 and it runs the signal through the mid boost amp only which I shall call “boost”. Anywhere in between and it blends a ratio of the “clean” and the “boost” signals to control the amount of extra mids wanted. Now it then gets very interesting because as the Volume control is increased, the “boost” channel starts to distort like a Tube Screamer and the Tone control allows blending of clean and distorted tones to produce a “transparent” sound which responds well to playing dynamics much like a Klon Centaur does. With the 5 way pickup selector, NoiseLess Vintage PUPs, TBX, Volume & Tone controls you actually have a versatile great sounding small pedal board on the guitar. Now for some notes on installation. I managed to install it without modifications to the guitar woodwork at all. 1) Put the PWB under the bridge pickup. Layer the cavity base with self adhesive tin foil connected to ground. Insulate the board from the foil with plastic and gently screw into place. Cover the top of the PWB with electrical tape to prevent shorting to the pickup poles. It should fit quite comfortably with care. 2) When replacing the output socket, carefully rotate the socket orientation, squeeze the lugs inwards and find a position that just fits the whole assembly. It will help to solder the signal wires to the inside section of the socket to allow maximum room to fit. 3) The battery will fit beside the Tone control if it’s inserted on its narrowest side and pushed against the cavity wall. A bit of double sided adhesive tape will help hold it on place. 4) I used a rechargeable 9v battery and installed a USBC socket through the scratch plate to recharge without having to disassemble the guitar each time. It’s quite time consuming but worth it. 5) The boost amp can become unstable if not properly decoupled from the supply so I placed a 100uF 15v electrolytic across the battery terminals. Keeps it very quiet. 6) Carefully study the TBX wiring as the picture supplied does not make it clear how it should be wired. There are schematics of the “Eric Clapton Mid Boost” on the web. Study those and use a DVM to buzz out the two ganged pots to understand how they work. Anyway that’s it. 3 hours of hard work and my old MIM strat is now an Eric Clapton Special for a fraction of the price. Definitely worth the effort !! Highly recommended !!!! Review: This was a fantastic upgrade for my MIM w/noiseless pups - I picked up a used MIM for use as a back-up guitar. Previous owner had installed Gen4 noiseless pups. It sounded pretty good but a bit too much contrast. Most strats are lacking in mid-tone, but this seemed ever more so. My first thought was to just a tube screamer to boost the mids. The I wondered how I could disassemble that pedal and put it in side my guitar. I did some research and ended up here. Saw this product advertised for $52 and thought how could I not. Installed it this weekend and it's excellent. It does the following: (1) like having a amp gain knob on your guitar, (2) expands the tone range of each pup, and (3) really does boos the mid-tone, although what it's actually doing when you turn the TBX knob is bleeding the treble/bass into a capacitor, effectively boosting mid. A few things to note: (1) if you're new to soldering, I would not attempt this. it's a bit more advanced and you can easily fry these parts if you dont know what you're doing. (2) the output jack did not fit into my MIM because its larger than the stock jack, so I had to dig out 1/4" of wood down inside, not a problem though. (3) the instructions are minimal so you have to do your homework on-line. ## Features - Country Of Origin: Mexico - Model Number: 0057577000 - Item Package Dimension: 11.99999998776" L x 9.49999999031" W x 1.099999998878" H - Item Package Weight: 1.0 lb ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003AYNJVA | | Best Sellers Rank | #51,613 in Musical Instruments ( See Top 100 in Musical Instruments ) #591 in Electric Guitar Electronics | | Color Name | Black | | Compatible Devices | Stratocaster | | Connector Type | 6.35mm Jack | | Customer Reviews | 4.3 4.3 out of 5 stars (119) | | Date First Available | June 8, 2005 | | Is Discontinued By Manufacturer | No | | Item Weight | 0.01 ounces | | Item model number | 0057577000 | | Material Type | Printed Circuit Board | | Output Wattage | 4 Watts | | Power Source | Corded Electric | | Product Dimensions | 11.42 x 7.48 x 3.54 inches | ## Product Details - **Brand:** Fender - **Color:** Black - **Compatible Devices:** Stratocaster - **Material:** Printed Circuit Board - **Output Wattage:** 4 Watts ## Images ![Stratocaster Mid Boost Kit - Image 1](https://m.media-amazon.com/images/I/514HdAUO5VL.jpg) ## Questions & Answers **Q: I have a tele that came from the factory with the Clapton boost. Will the schematic include a two pot setup?** A: the strat kit is only for strat, they make a tele boost kit for tele's 2 knob. **Q: What are the dimenstions of the circuit board?** A: I have a Strat with bathtub pickup cavity and it fits right between the two Lace Sensor pickups. **Q: Does a conventional strat body need to be routed out to fit the pcb board and 9 volt battery?** A: No. You do NOT need to modify the body at all. Just installed this in a Fender Mexican strat without making any body modifications. **Q: What kind of pots are used? 250k or 500K?** A: 250 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gets a fabulous tone out of my strat !! *by T***M on January 25, 2024* Having installed and got it working in my standard strat it just sounds amazing and produces a huge pallet of new tones.

Simple to install and the different sounds are very usable in many different situations. The price is pretty hard to beat. If you can solder then I absolutely recommend this kit. Its pretty simpple to install. However im not sure if some cavities will fit the pcb and the 9 volt. It fits in a usa strat without amy mods. ## Frequently Bought Together - Fender Stratocaster Mid Boost Kit - Fender 5-way Selector Switch - The Art Of Tone Gavitt Pushback Cloth Wire for Electric Guitar, 22awg Pre-tinned Stranded Copper Wire, 10 feet of Each Color, Black/White/Yellow --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/7244943-stratocaster-mid-boost-kit](https://www.desertcart.be/products/7244943-stratocaster-mid-boost-kit) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-05*
