Tweedy

[ampgeek]

Looking for “Crucial sucky playing and terrible audio” sounds like an invitation that I just can't refuse. LOL!!!

I built-up my Tweedle-Dum in a prototype chassis that I use to "audition" circuits before committing to full-on builds. It has a single input with the V-1 triode sections wired in parallel. Each triode side has its own 1M volume pot. A treble peaker (ala 59 Bassman/5F6A) is strapped across one of the pots to allow the blending of normal and bright tones on-the-fly.

I also have an octal socket wired in parallel at the V-1 position. All else is per the Charlie Wilson provided plan.

These really quick-n-dirty Zoom recordings were made with a red base 5691 (industrial 6SL7) in the V-1 position, an early 70’s Les Paul Custom with SD Holy Grail pick-ups plugged straight in and two stacked 1X12” cabinets (one with a Scumback and one with a Weber Blue Dog).

I had originally installed a Heybor 8K primary OT. It sounded decent……but……not great. Kind of dry and sterile and lacking harmonic “richness” probably describes it best. I subsequently scored a couple of Steve’s (Member: 67Plexi) suggested Schumacher OT (K-58459, 7.5K primary). Those provided a huge improvement in tone and feel!

I will provide a couple of pictures in a subsequent post.

Cheers,
Dave O.

THANK YOU! For the audio. Sounds cool. I just may have to give in to the Tweedy craze.

Sounds and looks very nice!! Very similar to mine.

Here's the link to mine's presentation with the sound samples in the first post:

There are few more sounds posted throughout the thread as well.

Thank you gentlemen!

Although I really...really like the tone and feel of this circuit, I can't see it fitting into my gigging-rig anytime soon. It just doesn't fit my style and configuration at the moment.

Rock on,
