Graeme, I did not play in a band for 12 years, so I just had the little Hartke Kickback 115 for a practice amp. I just joined my current band, The Nailers, a year & a half ago, and I went out & bought the Eden Nemesis RS 400 amp & 4X10 speaker box. So now I use the Hartke for a sub amp & the Eden on top & it sounds AMAZING with the new SC SIgnature!
