The SDE-3 fuses the vintage digital character of the legendary Roland SDE-3000 rackmount delay into a pedalboard-friendly stompbox with a host of modern features.
Released in 1983, the Roland SDE-3000 rackmount delay was a staple for pro players of the era and remains revered for its rich analog/digital hybrid sound and distinctive modulation. BOSS reimagined this retro classic in 2023 with the acclaimed SDE-3000D and SDE-3000EVH, two wide-format pedals with stereo sound, advanced features, and expanded connectivity. The SDE-3 brings the authentic SDE-3000 vibe to a streamlined BOSS compact, enhanced with innovative creative tools for every musical style. The SDE-3 delivers evocative delay sounds that drip with warmth and musicality. The efficient panel provides the primary controls of its vintage benchmark—including delay time, feedback, and independent rate and depth knobs for the modulation—plus additional knobs for expanded sonic potential.
A wide range of tones are available, from basic mono delays and ’80s-style mod/delay combos to moody textures for ambient, chill, and lo-fi music. Along with reproducing the SDE-3000's original mono sound, the SDE-3 includes a powerful Offset knob to create interesting tones with two simultaneous delays. With one simple control, the user can instantly add a second delay to the primary delay. This provides a wealth of mono and stereo colors not available with other delay pedals, including unique doubled sounds and timed dual delays with tap tempo control. The versatile SDE-3 provides output configurations to suit any stage or studio scenario.
Two stereo modes include discrete left/right delays and a panning option for ultra-wide sounds that move across the stereo field. Dry and effect-only signals can be sent to two amps for wet/dry setups, and the direct sound can be muted for studio mixing and parallel effect rigs. The SDE-3 offers numerous control options to enhance live and studio performances. Tap tempo mode is available with a press and hold of the pedal switch, while the TRS MIDI input can be used to sync the delay time with clock signals from DAWs, pedals, and drum machines. Optional external footswitches provide on-demand access to tap tempo and a hold function for on-the-fly looping. Alternately, an expression pedal can be used to control the Level, Feedback, and Time knobs for delay mix adjustment, wild pitch effects, and dramatic self-oscillation.
The new BOSS SDE-3 Dual Delay Pedal will be available for purchase at authorized U.S. BOSS retailers in October for $219.99. To learn more, visit www.boss.info.
TWA CHEMICAL-Z
Roy Z signature overdrive pedal designed by TubeScreamer creator Susumu Tamura. Inspired by Maxon OD808, OD808X, and APEX808 circuits, Chemical-Z features the "Magic" IC used in APEX808 for less compression & more even frequency response than a standard 808. Increased output level. Two footswitch-selectable clipping modes - normal & hot.
Cory Wong—a funky player with his own signature-model Strat wiring.
Guitarist, songwriter, and producer Cory Wong is renowned for his solo work, his band Fearless Flyers (with Mark Lettieri, Joe Dart, and Nate Smith), and collaborations with artists such as Vulfpeck, Jon Batiste, and Dave Koz. His playing style is deeply rooted in funk rhythm guitar, with a heavy dose of rock and jazz. Well-known for playing a Stratocaster, his signature model was released in 2021, and it’s a unique offering. If you want to build your personal Cory Wong Strat, here is your shopping list, starting with the primary structure:
• Alder body, scaled down to slightly smaller than a regular Stratocaster, with Fender American Ultra body contours
• Maple neck with a rosewood fretboard with rolled edges, modern Fender American Ultra D neck profile, slightly larger headstock, 25.5" scale, 10" to 14" compound radius, 22 medium jumbo frets
• Locking tuners with all short posts, a bone nut, and two roller string trees
• Vintage-style 6-screw synchronized tremolo
• Hair tie around the tremolo springs (which mutes them to enhance the rhythm tone)
• .010–.046 strings (nickel-plated steel)
“While these are all interesting features, resulting in a very comfortable guitar, you don’t need to copy every detail to transform one of your Stratocasters into a Cory Wong-style Strat.”
For the physical build, as you can see, Wong and Fender created a real signature instrument to his specs and wishes. While these are all interesting features, resulting in a very comfortable guitar, you don’t need to copy every detail to transform one of your Stratocasters into a Cory Wong-style Strat. My personal favorite of these is the hair tie for muting the tremolo springs. A lot of my funk-playing customers are doing similar things on their Strats to get a dry sound, and they’re using all kinds of funny things in there, like foam, rubber bands, and pieces of cotton, as well as hair ties.
Now, let’s have a look at the electronics:
• Seymour Duncan Cory Wong Clean Machine SSS pickup set
• Standard 5-way pickup-selector switch with classic Strat switching matrix
• 250k master volume pot with a 90/10 audio taper and Fender treble-bleed circuit PCB
• 250k tone pot with a 90/10 audio taper and Fender Greasebucket tone control PCB for only the neck pickup
• 250k audio push-push tone pot with Fender Greasebucket tone control PCB for only the bridge pickup; the push-push switch overrides the 5-way switch and defaults to middle + neck pickup (in parallel) as a preset
• Middle pickup is without tone control
Let’s break this down piece-by-piece to decode it:
Pickups
The pickup set is a custom SSS set from the Seymour Duncan company with the following specs:
• Overwound hum-canceling stacked bridge pickup with a 3-conductor wire and shield in permanent hum-canceling mode (red wire taped off), bevelled alnico 5 magnets, approximately 14.5k-ohm DCR
• Overwound middle single-coil, RWRP, beveled alnico 4 magnets, approximately 7.1k-ohm DCR
• Overwound neck single-coil, bevelled alnico 4 magnets, approx. 7.0k-ohm DCR
The pickups are voiced for clear highs, which perfectly suits Wong’s funky playing style and tone. While a lot of pickup companies will have pickups in that ballpark, it will be difficult to put together a full set that really works as intended. The Duncans in the Cory Wong Strat are available as a balanced set, so if you want to get as close as possible, I think this is your best bet.
5-Way Pickup Selector Switch
Nothing special here, just the standard 5-way switch with two switching stages that is wired like a classic Stratocaster:
bridge
bridge + middle in parallel
middle
middle + neck in parallel
neck
The upper tone pot is assigned to the neck pickup, while the lower tone pot is connected to the bridge pickup, leaving the middle pickup without tone control.
Master volume pot and treble-bleed circuit.
The 250k master volume pot is a standard CTS pot with a 90/10 audio taper found in all U.S.-made Fender guitars. The volume pot has the treble-bleed circuit from the Fender American Pro series, but uses a ready-to-solder PCB from Fender instead of individual electronic parts. The PCB is available from Fender individually (part #7711092000), but I have some thoughts about it. While using a PCB makes a lot of sense for mass production, it has some downsides for us mortal human beings:
• Soldering on PCBs requires some training and also special soldering tools.
• The PCB is quite expensive, while the individual electronic parts are only a few cents.
• The PCB uses ultra-tiny surface-mount parts, so it’s very difficult to repair or mod it to your personal taste.
I don’t think we need a PCB for adding a treble-bleed circuit, so let’s do this project using conventional electronic parts. The treble-bleed PCB contains a 1200 pF capacitor with a 150k-ohm resistor in parallel, plus another 20k-ohm resistor in series. Using individual parts, it looks like this:

In general, a treble-bleed circuit will help you to combat the “volume vs. tone problem” when using passive single-coil pickups. When you turn down the volume (even just a bit), the high end or treble loss is not proportionate. In other words, a small cut in volume creates a far greater loss in your guitar’s treble response. Using a treble-bleed circuit is an easy way to get rid of this problem, as long as it is calculated carefully.

Next month, we will continue with part two of the Cory Wong Stratocaster wiring, bringing it all together, so stay tuned!
Until then ... keep on modding!
