Here's the TS7...

...well pretty much anyways.  I traced out the "hot" switch part of the TS7 to see how it works, and this is what it looks like

They're just using a DPDT switch to change the 4K7/0.047uF setup with a 1K/0.47uF and they're also doing some things with one of the capacitors in the tone control section with the switch too.

I really like the Hot switch setup on the TS7...it really adds quite a bit of extra overdrive and saturation!

Thanks for the schematic Phillip. I have wondered exactly what they were "doing" with that switch myself. I figured it was something similiar to what is on your schematic, but the switching of the cap just before the tone control section is a cool surprise.

This goes back to a Jack Orman note on TS mods where he mentions  changing the stock .22uF to a .1uF to open up the tone control a bit. It will definitely brightens things up. By switching in the .47uF cap in series with the .22uF you would essentially have a .15uF cap when in the "hot" mode.

To my ears I have found that when you start modding TS pedals for more gain it does tend to get a bit more muddy when the gain is at extreme settings. I guess Ibanez felt the need to brighten up the higher gain setting as well.

thanks again for the drawing!

take care,

I know a lot of people dog the tonelok pedals, but i really thing a few of them are great, expecially the TS7, and the DE7  

I just HATE the crappy switches.

other than that they are great.  I think i am going to put one in a 1590bb soon

i have two of them.
