Onboard Preamp, J-Retro and U-Retro Onboard Bass Electronics – East-UK.com

East-Professional was formed in 1998 initially to market the J-Retro 01 drop-in retrofit predesigned for J style basses. The J-Retro unit fulfilled a need for creator John East to construct an onboard preamp for jazz and J style basses. Our latest version is solder free. All you have to do is assemble the device via the screw terminal inputs. This led to the creation of further products, such as the U-Retro onboard preamp. Demand for our onboard bass electronics systems has seen the company gain a customer base in the USA, Australia, mainland Europe and Japan. All of our products have been designed and made in the UK, with high quality components used throughout. These include parts such as ‘Switchcraft’ jacks and custom ALPS pots. Hardware, such as the knobs and plates have been designed in house and are custom made. Our range of onboard bass electronics and onboard preamps has been adopted by professional bass players in the last 10 years since East UK came into existence. For instance, a writer for ‘Bass Guitar Magazine’ swears by the U-Retro system. Our onboard bass electronics company is based in rural Oxfordshire, and is just off the M40 motorway, near the A34 and A41 roads. For onboard bass electronics which have been lauded by professional players, East enables you to hit the right notes. For professionals and budding amateurs, you will be blown away.
