Paolo Gregoletto

Paolo Gregoletto, at the age of 19, extensively used the Kustom Groove 1300HD 1200-Watt Bass Amp Head during a tour. His setup included two of these amp heads, delivering powerful 1,200-watt sound, paired with Groove Bass cabinets. Paolo praised the setup for its impressive low-end and stage-shaking power. The only addition to his rig was a Sans Amp pedal for added tonal versatility. This information was shared in a forum discussion referencing details from the Kustom website.

"It was during that tour that then 19-year-old bass player Paolo Gregoletto first truly roadtested his Kustom Groove Bass stage rig. That rig consisted of two Kustom Groove Bass 1200 heads (1,200 watts each), two Groove Bass 410H cabinets (each loaded with four 10-inch Eminence® speakers and compression horn drivers) and one Groove Bass 215H cabinet (loaded with two 15-inch Eminence speakers and a compression horn driver). “Not only have I gotten the tone I want,” says Paolo, “but I am able to crank it with 1,200 watts of immense power! The low end is amazing. It literally shakes the stage every night.” When asked about any other elements of his stage rig Paulo says, “The only thing I use in between my bass and my Groove Bass rig is a Sans Amp pedal to give it a slightly dirtier sound when and if I want that.”" kustom.com

On a forum I saw someone quote the Kustom website. I couldn´t find that article but this was the closest thing I found to what bass amp he uses. (It´s essentially the same as the 4x10 he uses but equipboard doesn´t have that one).

In this interview Paolo says he uses Ampeg SVT profile on his Kemper. He also stated on his twitch channel that he actually owns and uses it.

At 14:52 Paolo proceeds to talk about his use of the Kemper.

He praised the rig for delivering powerful low-end tones, stating, "The low end is amazing. It literally shakes the stage every night." Additionally, he mentioned using a Sans Amp pedal for a dirtier sound when desired. While the forum user referenced a Kustom website quote, they noted that Equipboard doesn't list the exact model Gregoletto used, instead resembling the Kustom Groove 2x15.
