Too much bass is a guitar player's worst enemy.
We very much agree on this.
Most guitarists don't really understand why this is true, but at the very least, you have to leave room in a mix or a live performance for the bass and the kick drum.
Today I plugged the 20th into my amps with the neck pickup all the way up and the tone all the way up, and I gotta say, it was very bright. I usually roll the tone off a bit to darken it a little.
So definitely, different tones for different players! But our different amps may account for some of this, see below.
I also have a little Glaswerks Zingaro combo (Dumble clone with Skyliner tone stack) and a Dumble ODS clone I made myself that has some strange twists to it and uses what's known as the Classic tone stack.
I played through 50 Watt Two-Rock amps when their amps were more like Dumbles (Custom Reverb Signatures 1, 2, Onyx, and Onyx Signature Proto and Sig 1) for a long time, so I understand where your taste is in terms of amp tones. The cabs I used them with were Two-Rock 2x12 with the oval port and G-12 65s, Bogner Oversized 2x12 with V-30s, Mesa 2x12 Recto cab with V-30s, and Mesa 3/4 closed back 1x12 with their Celestion Black Shadow 90.
Right now I'm playing the guitars I have mainly through two PRS amps - a David Grissom DG30 model, and an HXDA 30. These amps are a little warmer sounding than the Two-Rock amps, and of course, they're not trying to be like Dumbles. They're single channel amps. The HXDA is a Marshall Plexi style amp, and I roll off a lot of the treble because I usually have a bit of gain on and I like to keep it warmer. The DG30 is sort of a combination of Tweed, AC30, and other vintage amps kind of rolled into one package that sounds fantastic, and I run it on "clean to edge of grit" fairly bright, with its bright switch on.
I also have a Mesa Lone Star 212 100 watt combo that I use for certain things; it's more of a Blackface kind of sound clean, with an overdrive channel that's probably unlike their other overdrive amps, it's really a clone of the clean channel with a bit more gain, with an optional additional overdrive circuit that can be switched in or out. I usually switch it in. With this amp, I run the clean side fairly bright.
Since our amps are very different, that may account partly for our different opinions regarding the need for a brighter neck pickup tone. I mostly use the neck pickup with my cleaner amps. And as I said, I tend to run them a bit more on the bright side.
