Background: I've been playing Twin Reverbs consistently now for the better part of 10 years. While I was a musician in the Army, I had access to a number of Reissues that served me well for a variety of uses. I loved the ones at work so much that I ended up buying my first TRRI back in 2012 and have never been without one since. Over the years, I dabbled in other amps at work and in my civilian playing, but always came back to the twin for it's tone and volume. Not surprisingly, the Twin Reverb became "my" sound over the years. One of the TRRI we had at Ft Bliss had a speaker swap done before I arrived, it had Eminence Legends in there. That amp in particular was fantastic. I remember it being more balanced and perhaps more musical as a result of just the speaker swap. The other TRRI during that time included a then new 68 custom which was a fine amp and my own, a Guitar Center special edition TRRI in white tolex with a oxblood grille. My white TRRI was the exact same amp as the standard 65 TRRI, just with different cosmetics. However, I eventually retubed mine and had the shop bias it hotter per my request. I knew even less back then about amps and it seemed like a cool and easy way to lower the headroom so that I could push the amp harder. That white TRRI sounded incredible and it definitely is the one that got away ampwise. Currently, I have a TRRI from the early 2000s that I bought off the original owner here in Boston for a good price and excellent condition. I did the typical thing and had it looked at and serviced by an expert tech. After playing TRRI's so much over the years, I have begun to wonder if there is something else out there that I can do to mine. I'm not unsatisfied with my amp and it certainly does what I require out of it. Alternatively, my Marshall stack being a completely different approach just begs to be played and I always feel inspired when I fire it up. At this point, I think swapping speakers would be the easiest and most effective method for accomplishing what I want out of the amp. The idea being that different speakers would liven up the sound some. What mods have people done to their TRRI's besides speaker swaps? What amps exist in the same territory as the TRRI? What types of speakers should I consider for a possible swap? Am I just being an insufferable moron who is being incredibly trivial and non productive?
