Pre-Wired OBEL Jack Plate
Fitted with Switchcraft 12B TRS jacks, and pre-wired with 8-10 inch leads, this is the easiest way to incorporate an obel system into your existing guitar set up. Although this features pre-wired jacks, you will need to solder the other side of the leads to different places within the guitar to insert the OBEL circuit. This plate is a direct replacement for a Stratocaster jack plate. Also available in “plate only” format, without jacks or wires. Includes Carling DPDT switch for use with OBEL.
Instructions:
OBEL Jack:
Yellow: OBEL Send (connects from your OBEL bypass switch - or directly from your buffer out if no bypass switch). Connected to “tip” of northernmost TRS jack.
Blue (or purple depending on stock levels): OBEL Return (connects back to your OBEL bypass switch, on the terminal that returns the signal to your volume knob input). Connected to “ring” of northernmost TRS jack.
Black: Ground (main ground bus) (shared between the two jacks).
OUT Jack:
(same wire as last step) black ground wire to your main ground bus.
Connect the green wire (connected to the ring terminal of the TRS) to your 9V battery ground (black/negative).
White: Output hot (connect from your volume knob output).
Note:
While OBEL systems technically can be implemented in passive formats, using a buffer is highly recommended. In a passive setup, a 250K or 500k potentiometer in the volume position is standard. However, to avoid squeal and other unpleasant sounds, I recommend you use a Waldotronics buffer and 25k or 10k potentiometer in the volume position with any OBEL-equipped guitar.
