0C3 Guitar Amp Controlled Smooth Sag

Thank you K. O'Connor for clarifying your goal and the gentlemanly manner in which you did it.  I'm pretty excited today because while building I use a Variac and old tubes just to avoid damaging anything really decent.  I'm nearing completion now and just got a matched pair set of the Chinese Gold Lion KT-77s.  They bought the name Genalex and perhaps they understand how high end Genalex was back in the day because these tubes/valves are excellent.  They didn't slack on these bad boys. They test strong and they sound superb.

So I have 2 clips for your audio enjoyment and critical listening.  The first one is at the very earliest stages of edge of breakup with single coil pickups.  The guitar is a vintage Silvertone "Lipstick Tube" and the quick 'n dirty phone recording cycles through Neck > Both (parallel) > Bridge.  The amp is playing through an open back cabinet with 2x10 inch speakers from a Bassman 10.  Check out the clean sustain and low noise floor at the end. They are 32 ohm speakers in parallel.

The second clip I think even as nasty as a quick phone recording is, demonstrates the extremely gradual transition into overdrive  which makes this design especially "vocal" according to touch and guitar controls settings.  This clip is wide open in the preamp, both gains dimed, and the Master Volume (which doubles as an FX Return level control) a nudge below "2" out of 10.  It's not loud in the room, likely under 90db.  With this Tone Stack the gain and where overdrive occurs first (in which frequency band) varies wildly with controls this interactive.  However I left the tone controls close to midway throughout and this clip is the single coil bridge pickup only.  Ultimately it's to demonstrate max distortion with single coil pickups but the fist chord you hear is with the guitar Volume Off, then advanced in steps.  It's easy to hear how the transition is wide and gradual.

Anyway my playing skills are horrendous from severe nerve damage but this was just a basic test, so here goes...

Clean-ish




and all out...


DIMED (master less than 2)



I can't wait to hear it with the Jensen C12N.
