Those amps are not tight by any stretchy imagination. This little or no bright cap either dialing out the bass becomes a major pain in the ass.
I had the Marshall JTM 45 reissue years ago, and I had the Metropoulis Super- Plex too. Monstrous low end that I could not dial out, drove me crazy.
That being said, I’m thinking about the Marshall ST20, after watching Greg Koch get amazing sounds with his.
