A+ by Shift Line Flex with Pavel Paukov

A by Shift Line Flex tube bass preamplifier with Pavel Paukov The A Flex is a tube bass preamplifier aimed at players who prefer the classic East Coast sound. The A Flex is a fully analog preamp based on the 12AX7 tube. The device allows for soft compression and characterful harmonic saturation while also giving you control over your instrument’s tonal balance and volume. The Flex has three outputs (main, balanced and THRU) allowing you to set up multiple independent signal chains. Additionally, you can use the device as a drive pedal or toneshaper due to its bypass switch.
