I have some money saved and I'm pondering whether to upgrade my rig: Thinline Telecaster -> bunch of pedals -> Acoustic 270 head -> Jet City 2x12" with Celestion G12H-100's I'm really satisfied with my tone. The Acoustic is rather "dark", which is nice with a Telecaster. The Celestions don't fart out even at higher volumes (the 270 gets LOUD) and they impart a bit of dirty Celestion flavour. I like a "neutral" base tone for my pedals, so it's a good rig for me overall. Not sterile, but "**** in->**** out" (in a good way). GAS being what it is though, I'm wondering if the Jet City cab might be the weak link. Would a more expensive cab really sound that much better? The JC is nice and light plywood and it seems well built. I could take the amp to a music store and try a few cabs, but in the end I'd need to test drive a cab under rehearsal conditions to really know if it would work for me. Has anyone made the jump from a decent mass-produced cab to something like an Avatar or better and felt it was worth the money? I'd reuse the G12H-100's btw.
