- What does OBEL mean?
OBEL stands for On-Board Effects Loop. It is a wiring design inside the guitar which uses a separate 1/4" stereo jack to allow the direct output from the pickups to go to effects pedals and then back into the guitar for post-effects volume control. The purpose of the OBEL is to allow for volume adjustments on the guitar after being processed by effects. You may notice that distortion and envelope filters respond differently with volume adjustments on a standard electric guitar. Using an OBEL allows for consistent response from your effects pedals/processors at any guitar volume.
- What is required to use the OBEL?
We recommend to use a junction box with a stereo 1/4" guitar cable to connect the guitar to a junction box (a stereo Y-cable can be used instead). A junction box looks like an effects pedal. It has a 1/4" stereo input jack on one side, which is where the stereo guitar cable from the guitar's OBEL jack plugs into. The other side of the junction box has 2 mono 1/4" jacks. One of those jacks is a send to the input of your effects the other is a return from the output of your effects. Using one mono guitar fx patch cable, connect the send from the junction box into the input of your first effect pedal, and the the return from the junction box plugs into the output of your last effects pedal in the chain.
- Can an OBEL equipped guitar be plugged in like a standard electric guitar with one cable using just the mono guitar output?
Yes, you do not have to use the OBEL in order to plug in your guitar to your effects. Â You can simply bypass the OBEL using the OBEL bypass mini-toggle switch on the guitar and use the guitar as a standard electric guitar with your effect pedals plugged in-line between your guitar and amp.

- Do I need to have a 9V battery installed at all times to hear sound?
The answer is yes.  You do need a working 9V battery installed at all times to hear sound coming out of the main output, even with the OBEL bypassed.  The pre-amp is always active in the signal and the pre-amp is powered on by plugging in a guitar cable to the main output.  To save battery life, unplug the guitar cable when not playing your guitar.  If you accidentally leave the cable plugged into the guitar, the battery would drain out in about 2 weeks, that's about 14 full 24 hour days of battery life from a single 9V. We do offer a Pre-Amp Bypass Upgrade option for OBEL equipped guitars that will allow you to bypass the Pre-Amp should the 9v battery power drop down too low to power the Pre-Amp properly.
- The OBEL doesn't seem to be working. When I flip the toggle into the OBEL, I get no sound. My OBEL guitar isn't working with the HubBub Junction Box.
The Godfrey Daniels HubBub Junction Box is wired Tip to Send, and Ring to Return. Sometime in 2018, we made sure that PHRED instruments guitars moving forward are wired with the OBEL I/O jack on the guitar to be compatible with the Godfrey Daniels HubBub and HubBub Stage Pro Junction Boxes.
If you are experiencing issues with your OBEL equipped guitar and a Godfrey Daniels HubBub Junction Box, there are few things you can try to troubleshoot the issue.
Test #1
1. Plug a regular mono guitar cable into the Main Output jack on the guitar. The other end of the cable should be unplugged. This is just to power on the pre-amp, if your guitar has a pre-amp. Most guitars with OBEL have a pre-amp.
<!-- wp:embed {"url":"","type":"video","providerNameSlug":"youtube","responsive":true,"className":"wp-embed-aspect-16-9 wp-has-aspect-ratio"} -->
2. Plug another standard mono guitar cable into the OBEL I/O jack, and the other end of that cable directly into your guitar amp.
3. Put the MINI toggle into OBEL mode, and you should get sound if the OBEL jack on the guitar is wired correctly. The volume knob on the guitar won't work in this test, and that's ok, as the volume on the guitar is bypassed for this test. Here's a video that shows how to perform the test above.
Test #2This test is mostly specific to PHRED guitars with copper foil inside the electronics cavity or with a dual output jack plate. If you perform Test #1 above and don't get sound, we'll need to make sure that neither the tip or ring lug on the OBEL jack are grounded somehow to the copper foil inside the electronics cavity. You can visually inspect for this by removing the electronics panel on the back. If any part of the OBEL jack is touching one of the screws that is securing the Dual Output Jack plate, then there could be grounding. The best way to check is with a multimeter. Here's a video on how to test for that.

The FixIf you have performed Test #1 and Test #2 (inspected for grounding of the tip or ring lugs, and there is no grounding, and also no sound from Test #1) then it's recommend to swap the wires that connect to the tip and ring lugs on the OBEL jack. This will require soldering. Here's a video that shows which wires need to be swapped.
<!-- wp:embed {"url":"","type":"video","providerNameSlug":"youtube","responsive":true,"className":"wp-embed-aspect-16-9 wp-has-aspect-ratio"} --> - Do all effects pedals need to be in the effects loop, in other words, can an OBEL equipped guitar have some effects in the effects loop and other effects outside of the effects loop? Â Â
Effects like delay, reverb, noise gate, limiters, and compressors can be placed inline between the standard guitar output jack and your amplifier so that those effects are always on and/or always accessible to you whether the OBEL is engaged or bypassed.

Body
The body features a triple-humbucker setup mounted in a custom pickup plate, with discrete split coil switches and a 5-way pickup toggle for 14 different tone combinations! There is one master volume and 3 tone knobs, allowing you to dial in tone that goes from dark and muddy to crisp and bright. There are two 1/4″ output jacks on the side of the body. One of them is a standard guitar output to plug in a standard guitar cable. The other output is used for the built-in on board effects loop (OBEL), allowing you to gain further control of the sound coming from your effects pedals. Scroll down below to read up on the benefits of having an OBEL equipped guitar. On the back of the guitar, there is a large and accessible electronics cavity and a 9V battery box that powers the internal built-in preamp. The built-in pre-amp boosts the signal a small amount and lowers the output resistance so that the signal is better preserved along the guitar cable to your amp. We offer an optional custom hard shell case to go with the Wolph guitar.
Neck
The maple core neck is attached to the body using very strong wood glue. The back of the neck contour is a C-shape that feels somewhere in between a strat and an LP neck, not too thin, and not too chunky either. The 2-octave fingerboard has 24 medium jumbo frets which are leveled and milled here at our shop in California for a nice smooth feel along the edge of the fretboard. The fretboard features a 12 inch radius which is perfect for soloing and playing chords up and down the fretboard. Topping off the fretboard are custom pearloid inlays designed by PHRED instruments. At the top of the neck, you’ll find a bone nut for good sustain, and white binding all around the fingerboard for a uniform look and feel. The tilt-back 3+3 headstock shape is inspired by Cripe’s headstock with some visual design changes. Under the fretboard is the adjustable double-expanding truss rod, keeping the neck stable in any climate.

13-point Setup
Our 13-point setup and inspection ensures that every PHRED Instruments guitar we ship is professionally setup and ready to play when it’s delivered to you. Setup will include string-height adjustment, intonation, electronics inspection, and the frets are leveled, crowned, and polished, as outlined below.
Fretwork and Fingerboard
1. Debur Fret Edges
This process involves filing the edges of each fret such that the edge of the fretboard feels smooth as you play up and down the neck.
2. Level Frets
Leveling all the frets ensures that you can play at low string action and with clear and articulated notes on each fret.
3. Crown Frets
After leveling the frets, they are crowned. Crowning frets is a process by which the frets are rounded slightly at the top. This makes the frets feel nice and smooth all around, ensures smooth bends, and also makes it easy to slide up and down the fretboard.
4. Polish Frets
After crowning the frets, polishing makes them shine brightly. Polishing them also makes them even more smooth to the touch.
5. Condition the fingerboard
The fretboard wood is cleaned and conditioned using fretboard oil.
Setup
6. Adjust Truss Rod
The truss rod should be adjusted such that the neck is slightly concave.
7. Adjust Nut
The nut height is adjusted to the fingerboard, and the string slots are filed to a perfect height and width for the strings we install
8. Adjust the Bridge Height
As a part of setting the string action, the bridge height is adjusted to our standard measurement of 1.75mm above the 12th fret on the low E string, and 1.5mm above the 12th fret on the high E string. We leave a little bit of room if you want to adjust the bridge a bit lower than that.
9. Adjust the Bridge Saddles
Intonation is set by adjusting the bridge saddles. We tune up and stretch a fresh set of strings, and then adjust the bridge saddle position until the harmonic at the 12th fret compared to the note at the 12th fret.
Pickups
10. Adjust pickup height
The height of the pickup is adjusted such that the perceived volume is consistent between each of the pickups installed on the guitar.
Electronics
11. Inspect and test electronics
Whether you upgrade to our USA wiring option or go with the stock wiring and electronics, we are going to make sure all the electronics work properly prior to shipping. For guitars that have an OBEL jack, we wire it Tip=Send, Ring=Return.
Strings
12. Install D’Addario 10-46 gauge strings
We install D’Addario EXL 10-46 gauge strings on all guitars. If you prefer a different brand or string gauge, contact us and we can accommodate other brands and string gauges, and adjust the setup accordingly to the strings that you prefer to use.
