Moved the NFB to the 8ohm tap. Changed the PPIMV resistance to a measured 220k-230k using a 1M resistor over the pot. Got rid of the cathode bypass cap and the snubber on the 3rd stage. Upped the 1st stage snubber cap to 220p. Got rid of the grid resistors on 2nd & 3rd stages. 3rd stage hot shield removed. Upped the 1st stage coupling cap to 22n. Final stage voltage divider returned to a more typical 470k//470p-470k arrangement. Increased the PI B+ node voltage.

Very nice! What mic are you using to record with? One thing I've noticed with your samples is that you have good mic placement. I'm assuming you pretty much keep it in the same place when you record? Moving that mic just a little bit can completely change the sound on a recording, but it sounds pretty consistent in your recordings.

Thanks. I'm using an SM57, positioned about 25mm away from the baffle, aimed at the outer edge of the cone at a slight angle. Yeah, the placement is very sensitive. I've got it set up on a mic stand that has it's feet butted up against the cabinet. This helps me position it back to the same spot if I happen to move my cabinet. I haven't moved it for some time, so as you mentioned, all the clips should be fairly consistent.

Your welcome. That's a great idea about having it set up against the cabinet in a way that helps you to keep in the same place. I couldn't help but noticed the consistency on your tracks with your recordings. I also figured you were using a SM57. That's what was used for Slash in the studio from AFD to SI, and probably at least first Snakepit album, as Mike Clink was the producer for these albums and has stated that's all he used on Slash's tracks. So if your going to try and nail the sound in a sample recording this mic is key as other mics will have a different sound and frequency response. So good choice! This is a great mic, and I love it for guitars.
