If you are searching for the ULTIMATE tone and pedalboard, this review could be a game changer. This month I’m excited to show you several magical boxes you never knew you needed, but once you get them, you’ll never be the same.

The Interfacer, Underfacer, Output, Isolator, Audition, Buzzkill, and a remote switch RMT.

Way down under in Sydney Australia, are a couple tone gurus, Grant and Mikey. They have a unique full service pedal board company called Goodwood Audio. These guys build the coolest custom pedal boards via the mail for top players anywhere in the world (several of them worship guitarists). You send them your dream board specs, and then they assist you with a custom layout. They wire it up virtually with same size pedals, and mail it right back to you! You can also send them your own pedals and switchers, but the virtual way saves a ton on shipping. The good news is, these guys also sell their specialty Junction boxes that do things Pro guitarists need, and now you can get your hands on them too.

Goodwood is still the best-kept secret here in the USA. They have a few dealers and the buzz is growing among the ultimate tone junkies. Their unique Junction Boxes are rock solid, featuring Burr Brown Op Amps, and high-quality jacks & switches that are built for abuse. At first glance, you might be confused on why you need them, what exactly do they do or how they work. If you’re like me, once you get the “aha “ moment it’s all so obvious. For instance, how do I run my stereo rig into a mono amp?


Dual Mono Summing is pure genius! These are the two flagship units. They’re meant to be first and last on your board.

The difference is that the Interfacer goes on top and Underfacer goes underneath the pedalboard. The Interfacer has both Buffered and Passive inputs with a Mute/Sum switch, w/LED on top. The Underfacer has a buffered input and because it’s under the pedal board, it uses the RMT Remote switch jack for Summing & Mute. Both also have a TX (transformer) version that adds an audio transformer for Ground lift and Phase. The Fuzz output goes into the Buffered input of Underfacer. The Underfacer mono out goes to a BOSS ES-8 switching system with loops for all my pedals. Then the Stereo Out from the ES-8 goes back into the Underfacer Stereo input. The Underfacer stereo out goes to my stereo amp setup. For the studio I also take the buffered Tuner out straight into my ProTools rig.

The Underfacer allows your stereo rig to be summed in mono. This is a huge problem solver when you only have one amp. Or if one of your amps dies in the middle of a gig, you can quickly switch to mono. I hate having to unplug a bunch of cables when I go mono. Underfacer gives you the option of two identical Summed Mono Outs so you still get all your panning delays etc but summed in mono. It’s a must have when you play live. I also really love it in the studio when I want to stack two mono doubled tracks. It’s amazing. I tried another thing, where I played a part with mono summing on the verse & went true stereo for the Chorus. If you run a mono pedal board or a two amp setup with one amp wet and one dry, you can set the Underfacer to mute just one side by changing the internal dip switch. This way you can easily mute the dry amp for spacious swells and ambient sounds with no dry signal. The TX versions also have a handy ground lift and phase switch. If you have a hum, or a mic/amp is out of phase it’s a real time saver. Lastly the Master Mute allows you to mute the whole board so you can change your pedals etc silently. I change out stuff all the time in the studio, and it’s a great feature.


Output is basically just the DMS™ Dual Mono Summing section of the Isolator/Underfacer units above. If you just need the ability to mono sum your stereo pedal board, this will do the trick. It’s smaller and can fit on top or underneath your board. It’s perfect for a smaller fly rig. It still has the Burr Brown Op Amps. There’s also a TX (transformer) version that also adds Phase reverse and ground lift. The summing mini switch is on the side. Like all the units it runs on 9v DC.


The Isolator is the perfect way to get a massive sound using three amps in what’s referred to as WDW or Wet Dry Wet. The idea is running all your stereo effects into the left and right amps with your middle amp running dry effects only. The result is a massive sound. I first heard this in LA when Michael Landau would play at the Baked Potato. It was the biggest most jaw-dropping thing I’d ever heard live. In a live venue WDW also gives your FOH a little more control over how much delay & verb etc is in the mix out front. If you kick into a solo he can bring up the dry signal to get you to stick out in the mix. I hear a lot of FOH guys complaining that there is too much FX on the guitar. It may sound just fine in your mix but he can’t get it to cut through. WDW solves the problem. Using the RMT remote switch, you can also mute the dry amp and just have beautiful ambient special sound for pads & swells. Another option is to use one great amp for your dry amp and a stereo amp simulator for the wet left & right. It’s a great solution. Since the stereo wet only signal is all FX, you’re not stressing as much about the perfect amp tone. It’s also a great way you can immediately go from a mono amp live, to WDW without having to buy two more Guitar amps. You just need to add a stereo DI.

Audition is a flexible junction box that lets you add pedals to your signal chain without the hassle of re-patching your pedal board. It’s based on a simple enough idea but Goodwood has brought it to life. It’s another must-have box. I fell in love with it immediately. In the studio I’m continually adding weird pedals for a session that just won’t fit on the board. It’s a pain to pry off the existing pedal, find cables and power, and then put everything back afterwards. Audition can be used for mono or stereo pedals. I could really use two of them on a studio board. I’d place one after my dry pedals, and one in the stereo chain. Super helpful too if you want to run into a piece of rack gear. All you need is a couple TRS to mono Y adaptor cables. For a fly rig you could use it for a Volume or Wah pedal. I usually have a separate Volume pedal on my compact fly rig because it won’t fit. FOUR CABLE METHOD: If you like to use the FX loop on your amp, Audition is the answer. Simply place it after your dry pedals (compressor distortion etc.) run the Send to your amp input. Next take the amp’s FX send back into Audition return and run the output of your wet effects back into the EFX return. The Audition is super handy, and it also has a 9V pass through for convenience.

The RMT remote is a solid tiny remote foot switch for the Interfacer/Underfacer Summing and master Mute and Isolator’s two muting options. Its LED is powered by either unit.

Goodwood Audio has come up with some amazing junction boxes for guitar players.

They’re the secret weapons and missing links of the modern pedal board world. I can’t imagine not having them on my board. I’m sure you will feel the same once you get one or two. If you have a stereo board you really need the Interfacer/Underfacer or Output solution. If you’re playing big venues the WDW Isolator will make your FOH guy happy. Audition is perfect for studio or for a fly rig. The products range in price from $75.00 to $299.00 depending on the options. I highly recommend checking them out.
