Alright, so I had some more time to fiddle with the Slampegg and figured I’d write a little bit. Nothing revolutionary here, but it’s so hard to tell what something will sound/feel like without physically trying it. Maybe my prose will help someone else, maybe you’ve heard all of this before! Sorry this will be so lengthy.
So I previously had a Fender Bassman 500, then a Bergantino B Amp, and now a Mesa D800. The Bassman had a really nice rich, heavy, complex mid sound with the Fender tone stack, and I really loved how it would get gradually more saturated in the mids as you turned up the gain, but didn’t really turn buzzy/fuzzy/farty. The B Amp was amazingly versatile, but I could just never get the low end slam I got from the Fender, and the overdrives, while sounding really good, never sounded as good as the Fender. It was always either too thin with the blend all the way, or when mixed with a clean signal, sounded more like an effect where it’s sitting on top of the clean sound. The D800 gives me that low end weight/slam, and I’ve been happy with it. However, that elusive sound…
I’ve played a bunch of different amps in stores and back lines over the years, and there are basically 4 that have stuck out to me as having a distinct sound like what I was describing. They all also happened to have a tube preamp section. So initially I wanted to try a UA to see if I could get that sound from a pedal. Also, 2/4 amps that had that sound were also passive tone stacks, so I figured that might be it (in hindsight, I almost always used my Fender at about 2-10-2, so not sure how much the tone stack was contributing). I saw a Slampegg show up used, and I figured that would be a good starting point since I could always flip it if I wanted to try a UA.
Guess what?
It has THAT sound, that quality that I heard and felt only a few times. It doesn’t lose low end, but more importantly, it doesn’t have to add it back in through a clean blend. It sounds like my bass, just more organically saturated. I’m not one to say you NEED tubes for certain sounds *ducks*, but I will say that I have yet to find this same quality without a tube. This is all very unscientific, but I won’t ignore a pattern.
Sidebar: I also bought a 12AU7 to try out, because I prefer lower gain sounds and not all out breakup. I had watched the YouTube clip where someone compared a space heater with 12ax7, 12at7, and 12au7 tubes. I liked more of the sounds that the U had from that clip, but when trying them myself, I felt like the X had a better sweet spot, even if it’s not as wide. This could be because my bass has fairly low output. I guess I’ll see if I can return the U.
Side-Sidebar: the 4 amps that had those qualities were the Fender (I got rid of it because it was too big, and I didn’t feel like I could get the clarity I sometimes needed), the Markbass Randy Jackson, an Ampeg V4B, and an Aguilar I played long long ago in a music store before they had released the TH.
