The Shift Line Stages is an overdrive with an excellent dynamic range and deep tone-shaping capabilities. If you're looking for a pedal with a meticulous response to your playing and great control over the tonal balance, the Stages is for you.

The Stages was primarily designed for use with electric guitar, but you can certainly run other instruments through it as well. For instance, the pedal works really well with bass (even despite the lack of wet/dry mix control).

A+ CabZone X is the new generation of our digital IR-based cabinet simulator. The Impulse Response Convolution technology provides a realistic sound and preserves the unique character of the cabinet and microphone used to record the impulse. We have taken into account user feedback to create a new version of a simple and convenient device that would allow you to play and record without having to use unwieldy cabinets and complex signal chains.

The A+ Flex is a tube bass preamplifier aimed at players who prefer the classic East Coast sound.

Here at Shift Line, we've always been particularly fascinated with bass-focused devices. Our product lineup includes the Olympic preamp with its "California sound", so the introduction of the East Coast-style Flex preamp was just a matter of time. We're extremely happy to introduce the new device, as the Flex can significantly expand your sound palette.

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.

The A+ Prism II is a new version of the Prism-9 complex effect pedal. Combining multiple techniques in a single unit, the device employs an outside-the-box approach to sound processing. The Prism II is comprised of subtractive and additive synthesis elements along with reverberation and various types of modulation (frequency, temporal and spatial). Rather than being lined up in a typical linear fashion, all parts of the system form a single "organism", allowing multiple parameters to be tweaked simultaneously. You could try and replicate it by using a chain of multiple time-synced effects — but that would be no easy feat, as the Prism II has 3 pitch shifting sections, 4 multimode filters, 2 modulation blocks, and a single reverb section. All the elements are organized in two identical chains (as the device works in stereo) with a separate mix section at each stage. The pedal's four LFOs provide extensive control over the stereo field and filter automation. The Prism II can be controlled via the TAP footswitch or synced to an external clock. Additionally, the device offers an expression pedal simulation mode along with a DETUNE function.
