Title: ODD effects ideas...
Post by: sir_modulus on June 19, 2004, 04:43:53 PM
just doing some thinking and thought of of two decent effect schemes . Wonder if they're any good or have been done before.

1: Put driver next to tube, amplify tube output. Driver has guitar signal, and original sig. and tube sig are blended.

2: Two wah pedals, both using a dual pot, or two 100k pots, so one pot is wired correctly and other is wired backwards.

Anyone know how these will sound?

Another idea, is to make an easy talking pedal. You take a bassball filter, and put a volume pedal in front if it. The boost will make the filter pitch go up, and the reduction will make it go down (kinda like a Wah Phaser)

You might want to check out Craig Anderton's Wah-Antiwah.

I haven't built or heard it, but it has two wah pedals set in opposite positions that then travel in opposite directions. There is a model of this effect on the Line 6 FM4 (stompbox) and Filter Pro (rack unit), but I haven't used one of those either.[/url]

I've built a circuit similar to Anderton's wah/antiwah. I used a 9V supply, and   a modest distortion stage precedes the filters, since the added harmonic content seems to add to the "vowel" (http://home.labridge.com/~tpe123/vowels.mp3) effect. The RC values for the filters were tweaked around until I was satisfied.

YES!!! Thats the sort of pedal I was looking for Tim (see previous topic on talking pedals). It's not hard, but produces a good kinda talking sort of effect. What circuit did you use Tim? BTW Tim, I love your site, I'm building Phuncygnosis and T.M.K currently. Thank you Travissk for the schematic, as I was looking for it. I have like 18 dual OPAMPS, and nothing to do with them, so I'm building all the dual opamp circuits I can find (next is a TS-9, with a switch for 9 or 808).

Anyone have ay idea bout the tube thing?
