NEW(old) TS adjustment

[Gus]

Back in the late 90's or early 00's a friend was unhappy about their live sound at stage volume(they were playing with Berine Worrel).  Using an open back combo and a TS the bass would be over driven and did not sound good in the mids or highs as well.
They asked me if There was something I could do to the TS

Simple and I have not seen anyone post this.  One reason I chuckle at the TS mods you see on the web.

I removed the 1uf coupling cap between the input buffer and clipping stage
installed a .1uf film cap and added a switch to switch in a 1uf film in parallel so you have .1uf or 1.1uf to the 10K
Marked it thin thick

The .1uf setting does not sound that good at low volumes in the house with just a guitar BUT a stage volume with a band the .1uf alone cleans things up.

I just got a TS board from Aion (the Stratus), and this looks like a great mod to use in that build. Thank you Gus.

interesting to know that makes such a big difference, Gus. i did something vaguely similar the other week, but with the 720Hz high-pass and low-pass areas in the TS. i used a pot and paralleled caps to turn the permanent HPF into an adjustable one, removed the LPF after that, and kept a James tone stack in place. so you can basically change the shape of the mid-hump using 2 controls (plus a post-gain Bass pot). there was a gain change of about 20% over the HPF pot's rotation, due to ESR being introduced by one of the caps, but it didn't significantly hamper performance and the guy loved it. maybe the ESR could be offset by carefully surrounding half a dual pot with resistors.

...well, i did say "vaguely". lol
