Used Xotic RC Boost

is widely considered a modern classic and a staple on professional pedalboards. The "RC" stands for Real Active, and its primary reputation is being a super-transparent clean boost.

Rather than heavily changing your guitar's voice, the RC Booster is designed to make your existing setup sound like "your tone, but better". It is so subtle and musical that many players use it as an "always-on" pedal to sweeten their base sound, enhance natural harmonics, and buffer against signal loss from long cable runs
