Ampeg has a proven record of producing high-quality amps and cabs with more than a nod towards vintage bass tones. The company’s stompboxes have also worked their way into the rigs of many top-name players.

With its latest launch, Ampeg is making a bold claim that the new SGT-DI gives bassists ‘an entire rig in a single stompbox’, but in trying to cram so much into one piece of kit, will some of the essence of what we have come to know and love about their products be lost in the mix?
