Basically I love the tone of my '66 Super Reverb with the bright switch up and volume set between 3.5 and 4.5- below that it's "tinkly" sounding, and anywhere above that it compresses losing bass and high treble. I plan on spending some quality time with the amp for the next few weeks, right now I use 2x12 Weber Cali speakers(like JBLs) and I plan on trying out Weber Michigans(like EVs), which should give me some more volume, plus some bottom end so I can back off the bass tone stack a bit more and increase headroom that way as well. Also trying a ss rectifier, and biasing the amp a tad cooler should help, as well as running a 5751 in the first preamp position. I'm sure all of these little details will add up and hopefully open a wider usable volume range for me, but for future reference I'm interested in amps that feature higher headroom and wider bandwidth- Two rock CR: I read a lot of comments about the clean channel on these sounding like a blackface amp so I'm inclined to skip them, I might as well use a BF Dual Showman maybe? Fender Dual Showman: maybe a slight improvement over what i'm using now Marshall Super Bass: I've heard they have great cleans, the concept of using a bass amp for wider bandwidth makes a lot of sense to me Hiwatt: since these were designed for guitar or bass it should be similar to the Super Bass but the Hiwatt power stage seems like it may break up slower? Any thoughts, negative or positive, on this whole line of reasoning is much appreciated as well as any info on amps that I haven't mentioned.
