I'm selling my Shiftline Olympic MkIIIS, a perennially out-of-stock,. astonishingly fully-featured tube preamp, cab sim, headphone practice amp... you name it.

This sounds beautiful, pairs well, can be an all-in-one solution, and it also has an FX loop. It's hard to do this justice in a small box so I've included a video so you can hear it in action.

UK postage will be via Royal Mail Special Delivery.

Please note this needs 12v at 650mA.

Manufacturer's description below:

The Olympic MkIIIS is the newest revision of Shift Line's bass preamplifier that combines the classic tube sound with modern audio processing technologies, creating a true "Swiss Army knife" for bass players as a result. Sculpting your signature sound and taking it anywhere you go has never been easier.

The Olympic MkIIIS is a compact, fully-featured tube preamplifier with a warm, deep and characteristically compressed sound. The device's universal connectivity allows to use it even in the most complex setups.

The cabinet simulation is based on the Impulse Response Convolution technology, which provides a realistic and detailed sound while preserving the character of the power amp, cabinet and microphone used to record the impulse.

The device comes with two built-in cabinet impulses: SUNN 200s 2х15 and AMPEG SVT-810E 8х10. The microSD card slot allows users to upload their own cabinet impulses.
