Up to a few days ago I was playing my Class 5 head through a standard 1960A cabinet with Celestion G12-75's. I haven't been very happy with the tone; I needed to turn the Bass way down and still it sounded boomy. The high end wasn't doing it for me, either. Out of desperation, I started researching mods and ordered parts from Mouser - I was ready to modify this monster!
About a week ago a pristine 1965A cabinet showed up on eBay, with stock Celestion G10L-35's. I won the auction and got the cab in a few days ago. The Class 5 head fit beautifully on top and I plugged it in. Holy smoke! A completely new tone came out of this combination! Gone is the boomy bass and glass, in comes a glorious sound! I was stunned!
I was originally thinking of replacing some of the stock speakers with Alnico Gold or Greenbacks, but I like this so much I'm not going to mess with it! Oh, and the mods will be shelved indefinitely.......
This is one match made in heaven!
