Description

Edit description

This is a full kit of parts that will enable an electronics beginner to build a very high quality KAT Treble Booster.

Firstly, a little info on this TB. For starters, the components provided are the best for the job in-hand. They are the same components used for the builds of many KAT TB’s and Fryer Sound TB Touring, Deluxe and Plus Treble Boosters. The circuit board has been specially designed for the kit so that the build can be easy with all components identified on the board. The case is the same powder-coated, silk-screened folded steel unit used for the TB Touring, Deluxe and Plus, so rugged, durable and yet, attractive.

Sound-wise, this TB has been developed to emulate the 1980’s era of Brian May’s tone with approximately 33dB of gain, so think Queen from the late 70’s through to the end. Think Wembley… Think Live Aid!!

So, what’s in the kit?

Well, everything you need to successfully build the TB except for a few hand tools and a battery.
