Comments about Celestion G12M Greenback 25W, 12" Guitar Speaker:

I am using one of these in my Peavey Windsor Studio combo(20 watts class A tube), driving two more of these and two Seventieth Anniversary 30 watt Celestions in a 4X12 cabinet.Initially I was disappointed,but not long after I realized I had not turned on my EQ pedal.The difference in tone and clarity was astonishing. I play mostly Blues and Rock on LPs ,Strats ,SGs and Jazz Fusion guitars and they all sound fabulous! Thanx Celestion !!
