After having my Fender Hot Rod Deluxe for a few years now, I finally decided to swap the stock speaker for an Eminence Red Coat “The Governor,” which is a moderately-priced ceramic speaker. What’s difference now? The Hot Rod Deluxe is a very mid-rangy amp in the first place, but at higher gain, the tone became a little flabby. In fact, when I knew I was going to play at gig volumes I had to dial down the bass to about 9 or 10 o’clock, and set the mid and high around 3pm to get a more crisp sound. I was able to alleviate a bit of that flabbiness with better tubes than the stock Groove Tubes, but I always suspected that the speaker had a lot to do with the flabby bottom end. I don’t know why I waited to do this simple, simple modification. It literally took 10 minutes to swap it out.
So why the Eminence Governor? Mainly because I wanted a nice mid-range focused speaker that had a smooth bottom end, and slightly sparkly highs. I had also played the Governor in a couple of different amps, and was really impressed with its brighter voicing. Here’s a frequency response chart for the Governor:
As you can see from the chart, the bottom end portion of the curve is a nice, smooth line. In the mid-range, the frequency response is fairly complex, then in the highs, you get some nice peaks in the 2-3 kHz range, finished off with some subtle motes above 10 kHz. The tone in the amp reflects this well. The bottom end is there, and very tame, and the mid- and high-freq response creates a gorgeous, and spacious tone. I’ll probably have some clips in the next few days, but here are clips directly off the Eminence site:
Clean
Heavy Distortion
Overdriven
All in all, this has got to be the most significant improvement to my Hot Rod’s tone!
