An amazing, do-it-yourself system that expands your guitar's tone.

The ToneShaper SW4B 4-Way Switch and Knobs for Telecaster with Two Single Coils replaces your Tele's stock wiring, quickly and easily, without soldering. It provides increased flexibility that you cannot get with any other product. Cool switching options. Customizable tone controls. Built-in solutions for dealing with treble loss that happens when you turn down. Simple installation, simple operation, top-quality components.

Switch Position Active pickups Hum-Canceling
Position 4 Neck No
Position 3 Neck + Bridge In Series Yes (assumes one RWRP pickup)
Position 2 Neck + Bridge In Parallel Yes (assumes one RWRP pickup)
Position 1 Bridge No

The ToneShaper SW4B is available in two basic configurations: conventional controls and reversed controls. Conventional controls are what you're used to seeing on your Tele, while reversed controls put the volume control at the front, the tone in the middle, and the switch at the back. Some people prefer this, as it provides more immediate access to the volume control.

Selectable Volume Pot Value
All Tele ToneShapers now have a selectable volume pot, so you can choose between 250k or 500k operation. The value of the pot affects the overall tonality of the guitar, even when the volume is turned all the way up. 250k is the traditional value used in Teles, and will produce a slightly fuller and warmer tone. Switching the unit to 500k operation will make the guitar a little brighter overall, which might benefit some guitars that are already inherently warm. It's easy to switch between the two values, so you'll be able to try both, and quickly determine what works best in your application.

Top Quality
This unit features top-quality components such as USA-made, 4-layer circuit boards. The two outer layers are ground planes that shield the internal circuitry from Electromagnetic Interference and Radio Frequency Interference (EMI/RFI). This is the state-of-the-art. The pots are CTS audio-taper with solid shafts, custom-made for this application. The switches used are Oak-Grigsby, just like Fender uses on their Custom Shop guitars.

Easy To Install
Mount the ToneShaper and switch to your standard Fender control plate (fits Callaham and Gotoh plates too, as well as most other brands). Your pickup leads and assorted ground wires just plug right in - quickly and easily - with press-and-release terminals. There is NO SOLDERING required. These connectors are simple to use, don't degrade the signal quality, and hold the wire very securely. Enjoy swapping pickups in and out of your guitars? Then you're going to love the connectors on the ToneShaper!

  • Provides for increased tonal variation
  • Revolutionary, patented control assemblies
  • Replaces the existing electronic controls in the guitar without soldering
  • Allows you to customize aspects of your control configuration, such as assigning tone controls to specific pickups, and customizing their functionality

Comments about ToneShaper SW4B 4-Way Switch and Knobs for Telecaster with Two Single Coils:

To get right to the point, this is THE upgrade if you're a tone junkie that likes to try different pick ups in your guitars. I absolutely HATE soldering, and frankly, I'm not very good at it. I also don't like having to pay a tech to do it for me. Therefore, this little gem is a total no brainer.

I purchased a Fender Baja Tele a while back, you know the one with the snazzy S-1 switch. Turns out, I loved the guitar..the neck was perfect and it played beautifully. But I hated the pick ups and the S-1 switch. So I decided to swap out the pups and ditch the S-1 and wire it up regularly with a 4-way switch. I came across the toneshaper, did a little research and decided to buy it and try it out on this Tele. It was absolutely the easiest install I've ever had to do on anything (contrary to the other review on this product). And once I had it all hooked up and chose the set up I wanted, I plugged the guitar in and was blown away. The pickups that had previously been dull and muddy sounding, now sounded...well, awesome. Beautiful Fender clean tones. The lows were thumpy and the highs were chimy, and all were very clear and articulate I guess you could say...just like a Fender should sound. I'm not really sure why this is, but it is. Somehow, this toneshaper thing brought these pickups to life...which saved me a chunk of change having to buy some new pups. Try this thing out. I've ordered another for my main strat, and I'll be ordering one for my #2 strat also and for every fender I ever own from now on. Definately a quality product.

    Comments about ToneShaper SW4B 4-Way Switch and Knobs for Telecaster with Two Single Coils:

    This is a great concept, but you may need to rout the tele bigger to fit it all in there. the wires need to be short as possible, but when they are short it's nearly impossible to get them into the tiny little slots. It's difficult to manipulate the springlock levers to the slots and install a tiny little wire and be able to see it. Just like soldering- you need 3 hands. Gave up and sent the whole guitar to my Luthier, which is what I was trying to avoid in the first place!
