I recently got back from my trip to the bass centre, and i played a josh Paul Cort/Elrick 5er through a GK Backline250 and a 400RB. It was through a GK cab aswell, and no matter what knobs i turned, i couldnt get that punch sound out of it. it had an amazing clean sound, but it felt like it had no ballsy slap sound. Is this just a con about GK or with a bit more playing can you get a good punch outta them? Im really thinking about Gk as my next (and first) 4x10 and head purchase, and with the type of music im playing, i need that ballsy slap sound.
