I’m running a couple of mother 32s into a Barbetta Sona 31 225W solid-state amp for a clean and wide sonic pallet. I’m wanting to add the ability to have some searing distorted tones ala John Lord albeit without the B3 and 100 W Marshall. I tried adding an MF Drive both in front of the amp and it’s effects loop, but at it’s extreme settings in both locations it only boosted the volume a bit without adding distortion. I also tried the Keeley Filaments, but it’s effects were mild as well.
I recently found the Effectrode Blackbird https://www.effectrode.com/products/effects-pedals/blackbird-vacuum-tube-preamp/ and the Victory V4 Countess https://www.victoryamps.com/v4-the-countess-pedal-preamp tube preamps. They both look like they might work well in front of the Barbetta. Has anyone tried these, or anything else to make the Mothers scream?
