***EMERGENCY*** I need Rebote 2.5 help tonite!!

[blanik]

hi all, i'm re-housing my beloved Rebote 2.5 in it's new home with some mods i made (a preset resistor (with a trimpot) mounted on a small switch to select either the delay pot or the preset delay (for a song that needs presise setting à la U-2) wich was easy to do since only 2 wires go to the delay pot...
and the other mod is a footswitch to set the repeat pot to max (endless repeats)
the box is all drilled, with the 2 footswitch and 2 leds... i thought i only needed to short lug 2 and 3 on the pot with the switch and use the other side (DPDT) for the led but shorting any lug won't produce the endless repeats... 

i need the pedal for tomorrow afternoon!  (i tried SEARCH but couldn't find precise info...)

thanks

Hmmm, shorting the lugs might well not work, a better way might be to use your switch like this:

the wire from the wiper of the pot moves to the pole of the switch,
the wiper now connects to one of the switch terminals
the top of the pot (the input side not the ground side) now connects to the other switched terminal

So you are switching the feedback loop level returned to the board from either the wiper OR the top of the pot.
That way you keep the load seen at the input side of the pot the same... AND you still get your LED switching.

Of course, your Rebote does go into endless repeats usually doesn't it............ (just checking.)
Good luck.

a thousand thanks Duncan! sounds interesting,

(((BTW shure i had endless repeats with the pot...  altough i'd like to get a little bit more but i just have to change the 10K for 9k or 8K and it should be perfect (for my taste), but it's pretty good like it's anyway)))

i checked a little with an aligator clip to short the wiper and the ground, i do get a lot more repeats but it's still influenced by the pot, so when the pot is set to many repeats, the shorting of the ground and wiper produce almost the endless rep, but if the repeat pot is set to few repeats, then shorting the wip and the gnd just sets it to longer but far from endless...

but switching the wiper to go on the board OR the ground would add resistance to lug 1 and 2 (by cutting it) so i guess it sounds logic.. i'll try it tomorrow morning... too tired tonite...

thanks..

What I was suggesting was lug 2 to a switch input, lug 3 to a switch input, and the output pole of the switch goes to the 10k feedback resistor. Lug 3 is the side which is fed from the 1uF capacitor NOT the side that goes to ground.

Like this....

THANKS DUNCAN!!!!!!! it works perfectly, i tested it.. now it's boxing time..   (the most annoying part but O so satisfying once over and working... lol)

sorry about the main title, it's not an emergency anymore, i tried to change the title but couldn't... 

i almost ffinished my re-housing/modding... all the tips i got here worked perfectly!!
i'm in my last miles on this effect, it's now fully stereo (actuated by mere insertion of a second jack) and it's got the infinite repeats footswitch...

i ran in a last problem, since the effect is stereo (a dry channel and a wet only channel), when i true bypass the main channel the sounds just stop coming out of the wet output and i need it to come out (dry) from both channels when in bypass mode...  so i rigged the 3PDT as a regular DPDT with a millenium bypass and used the remaining poles to connect a wire from input jack tip to output jack tip on the second output so when i bypass the effect (in stereo mode) it works perfectly (the delay even trails naturally after i bypass!!!!)

the problem is in mono mode (without any jack in the second output (i used a switching stereo jack, so when no jack is inserted the 33K res. goes back on the board like it's designed to do)), (in mono mode) in bypass mode the signal sounds a lot weaker!! when i activate the effect, a sudden sound cut occurs (annoying) and the sound is ok after with the delay... the simple option would be to put a mini switch on the side (that would cut the new wire when in mono) for mono or stereo operation but i'd like to do without it...
