First off, thanks to DaGeezer for sharing ideas and inspiration for this amp.
He has communicated with me off forum for several weeks about some ideas he was trying.
Originally this amp was a Carolina Overdrive Special (using a D-type tone stack) but was refined to use a 5E3 "tweed" tone control instead of a D_mble type tone control. Now the amp is called a Tweed Overdrive Special
This is sort of a cathode biased D_mble typology amp where I used a 5879 pentode in the second gain stage of the OD.
It has the most sustain, overdrive, harmonics and overdriven clarity of any amp I have built or played.
I can easily get the musical "blooming" type feature playing this amp. I can still get that feature with the VVR dialed down to 1/3!!!!
So it does NOT have to be loud to get those dynamics.
I am confidant the overdrive is in the preamp and OD section.
It sounds closer to what I see on U-toob as a Trainwreck.
It has more crunch, chime, blooming and sustain thatn the cathode biased D_mble that I built.
I can get notes to sustain into feedback and it sounds like a very musical sustain that blossoms.
I tried it with the band & got more compliments on this amp than any that I have brought to play (about 7 or so different amps).
Sometimes an amp sounds good at home but not with the band. This one sounded excellent with the band.
I honestly don't play well enough to fully take advantage of what this amp is capable of doing tone wise.
