Hi. I've got a Blues Junior NOS coming because I needed a small, light, low wattage grab-and-go amp. I'll give the stock Jensen in it a listen, but I feel pretty sure I'll be swapping it out for a British style speaker. These are the ones I'm considering: V30 G12H Hellatone 30 (not sure which G12H version this is- the Heritage, Anniversary, etc.) I'd consider a Greenback, but I think I want something that's more efficient for this amp. I'm looking for as much breakup as possible with the ability to dial in some strong mids. I play Americana, rock, maybe a little punk (in the vein of Neil Young, Tom Petty, Drive-by Truckers, the Ramones, Pearl Jam, etc.). I mostly play a LP Jr Special w' P-90's, and I've got a LP Standard and a Tele w/ a humbucker and P-90 so all my guitars can push an amp pretty hard. My other amps are a '76 Marshall JMP thru two Hellatone 60L's, a '66 Pro Reverb thru two Weber Legacies, and a stock 2x12 Blues Deville if that gives you any idea about my tastes. I'm looking for the pros and cons of using a V30 or the different versions of the G12H in a Blues Junior. Thanks in advance for the advice.
