How´s about some guts ?

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.
Here you go. Hope these help. Do you want some more?analogguru wrote:How´s about some guts ?

If your setup is noisier than his before the pedal (unshielded guitar with single coils?) any trem might 'thump'.
Testing, testing, won too fwee

A schematic would also be helpful too....
Genius is not all about 99% perspiration, and 1% inspiration - sometimes the solution is staring you right in the face.-Frequencycentral.

Sharp photo's of both component and trackside are the first step toward a schematic....

But a schematic should be findable on the internet,shouldn't it?....

Some parts are still unsolved, but I can tell you so far that it is a 4-stage switched capacitor phaser.

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.
I was using my LesPaul with humbuckers with Evidence Audio and George L's through my 63 Pro. Maybe I'll try another amp or guitar. The thing doesn't seem to thump when the rate is 75% - 100%. But, 0-75 thumps with the rate that the pot is set at.Hides-His-Eyes wrote:If your setup is noisier than his before the pedal (unshielded guitar with single coils?) any trem might 'thump'.
BTW, I didn't realize the Twister was still un-schematiced. I'm happy to share pics and info for any of my vintage effects. Maybe I should post them in the circuit analysis section though. This post was for help fixing my Twister. Thanks.

BTW, I think your unit has been on evilbay too, on 22.09.2010.

I am starting to draw PCB for this, and will post it here , but missing all capacitor values........also there are 3 empty places for resistors on yellow PCB..........
any help is welcome...

I am more than happy!!!
thanks...but please can you post cap values too , and what is written on those 3 transistors?
soon I'll correct my layout and make it to look like your original

Values: View left to right with wire connection side of board on top (all caps 100v, except when noted)
Top row: C1 green 102K - C2 green 472K - grey electrolytic? (values hidden underneath, although 35V is visible) - C3 green 222K - C4 green 104K - C13 green 472K
Next row: C15 Red .047K - C5 green 102 K - C8 green 102K - green 474K

Bottom row: Grey electrolytic? 2.2 uf 35vdc - green 103 K - 3 orange ceramic? 47K 1kv - yellow .2uf 200v - C12 green 104K - C14 green 474K - green 102K
Trannys: T1 PN 4303 - T2 NP 4250 ebc - T3 NP 4250 ebc
I triple checked for accuracy, btw.
