GraphTech PX-8843-BN 4mm Bridge Kits

Supercharger Kit for 4mm Tune-O-Matic Guitars – Black Nickel


Simply put, there is a lot of unused potential in your guitar tone and ultimately your guitar performance. These kits are specifically designed to enhance harmonics, reduce string breakage, and improve tuning performance for your acoustic or electric guitar. You owe it to yourself to hear and feel the difference Graph Tech components will make to your playing experience. Each kit comes complete with two grits of sandpaper to custom fit the components for your guitar.


Graph Tech combines our most popular components in one convenient package. For acoustic guitars, we combine a fully compensated TUSQ saddle that will unlock hidden harmonics and tone from your guitar and pair it with a set of TUSQ bridge pins.


Graph Tech offers two different types of SuperCharger kits for electrics. We have kits for Strat & Tele style guitars as well as guitars with tune-o-matic guitars.

For Strat & Tele style guitars, we combine a set of String Saver saddles, a TUSQ XL slotted nut and a set of TUSQ XL string retainers. We have five different kits for the most popular style guitars.

For guitars equipped with tune-o-matic style guitars, we offer either a 4mm or 6mm ResoMax NV2 bridge (loaded with String Saver saddles) and a slotted TUSQ XL nut.

Do you offer Next Day Delivery?
Yes, we offer a Next Day Delivery service for in-stock orders placed before 1pm Monday-Friday. Next Day Delivery and Saturday Delivery carries an extra charge. Ivor Mairants Musicentre commit to delivering on time, we rely however, on our carriers to fulfil their contract in this regard, and can not be held liable for any failure of third parties in fulfilling delivery expectations.

Can I change my delivery address after I have placed my order?
Once you have placed your order with us, we are unable to change any of the information you have given us, as most orders are dispatched from our distribution warehouse. Our contract carriers however offer various levels of free of charge enhanced service such as DPD PREDICT, which allows the consignee to be alerted by e-mail and/or text message of the delivery window and allows for changes allowed by the contract carrier to the detail of the actual delivery time and/or location. Where such services are available all orders will benefit from auto enrolment in the services. Ultimately, if there is no-one to sign for your delivery, you will be left a card by our contract carrier inviting you to collect from the depot or re-arrange delivery.

If it proves impossible to deliver your goods within the time allowed by our contract carriers, the consignment will be returned to us and you will unfortunately become liable for all redelivery, and/or redirection charges. Please check your confirmation email for the status of your goods before contacting us. Should you need to change your details, for example you have moved house, you can change your details by email at info@ivormairants.co.uk and the new information will be updated within 24 hours. Please note that any orders placed before changes are made will use your old details.

Can I track my order?
The vast majority of our UK and Eire domestic consignments and international shipments are by trackable service. You will be emailed a tracking number with your dispatch information. Please note that tracking numbers are not used for smaller orders sent by Royal Mail or similar postal service. If you require your order to be consigned using a trackable service, please advise us AT THE POINT OF ORDER.
