Battery clip

Hey guys,
I have a beginners question. If I want to leave off the battery clip, since I wont use the battery anyways, am I right to just connect the DC jack with the Inputs's ring clip?
Thanks

p.s.: the effect I'm building is the Lowrider octaver, which is +9V. I don't need the -9V which is often supplied by a battery.

No. Just leave off the clip. The DC jack gets wired as usual.

Just to make sure I understand that correctly: I do not conect the DC jack to the ring of the input jack and just wire it to the 9V input on the PCB?

thanks for the fast reply!

No, you still connect the ground of the dc jack to the input jack. Just leave off he battery clip and use a mono input jack instead of a stereo jack.
Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

thanks, that's basically what I've done. I'm still using the stereo jack, but just haven't connected anything to the ring. Sleeve is still grounded and the tip is the signal.

Just finished and gave it a first try! Doesn't work yet ;( Guess I have to look for bad solder joints.

Have a look at http://www.madbeanpedals.com/tutorials/downloads/StandardWiring_MBP.pdf
Leaving off the clip has the DC jack wired to (red wires) the 9V pad on the pcb and to the resistor+LED, and (brown? wire) to the sleeve of the input jack.

Thanks. Just what I did.

Still need some time to figure out what I did wrong. The board works now, but the upper octave is fuzzy like hell and the octave downs sound pretty much alike and don't produce a steady tone...
