    Hey,

    Wondering if anyone has tried any other IC chips in their Timmy? I'm wondering if an IC swap might take a little of the harsh edge off?

    Anyone tried anything in particular and how did that change the tone?

    Realfi should chime in here - I think he uses an LM1458 and asymetrical clipping mode in his to smooth it out some. Have you tried the dip switches first..?

    I do indeed!

    I find that combo works great for me. I tried a Burr-Brown op amp recently and tried the original JRC4559 chip back in the pedal but I still like LM1458/asymmetrical with the Vox and the Teles. The LM1458 removes just a little bit of harshness while the asymmetrical clipping seems to mimic the clipping of my AC30 turned up a bit louder.

    I should mention my Timmy is pre the recent mods that Paul did that brought it closer to the sound of the TIM.

    Even though I had Paul make me a TIM that can get the asymmetrical clipping sound, I'm actually preferring it in the least compressed mode with the stock JRC4559 as it's just a little smoother than the Timmy anyway.

    I liked the LM1458 better also....then tried the Brown - Burr OPA. So far the Burr is my favorite. The changes are not night and day, but it is smoother and sits better in my rig. It's definitely worth the time and a few $

    Where did you guys get the Bur Brown OPA chips?

    Realfi - how did you go about having Paul make a TIm that has the option for asymmetric clipping? Was it extra cost? Was the wait longer? I'm currently waiting for my Tim, which should be ready any day - is this something I can call Paul about and possibly have him mod this into it now or does it require a lot of additional work?

    I used a RC4558 in my TIM to knock of the Sterile high end that my amp seems to bring out of pedals.

    Where can one buy an LM1458? How are they installed?

    Thanks

    Yet another vote for the LM1458 with asym. clipping. I tried the Burr Brown but it just didn't do it for me- LM1458 is still my favorite.

    I've got some 1458's on the way but, I was going to try them in different pedals. Might have to put one in my Timmy instead. Question, how should the switches be set for assy. clipping? Thanks.

    One up one down.

    Doesn't make a difference which one is up or down if you're using the Timmy on its own but may in combination with another pedal so experiment.

    For you all using the 1458 chip/assymtrcl, what amp are you using?

    I've got a DC-30 that the timmy does seem too harsh with, but it's still stock. i've got a 1458, so i'll probably try that out soon.

    Yup. Like it much more than the 1458, has a cooler character to me...
