Maker: Goodwood Audio
Model: The TX Interfacer
Condition: New
Description:
The Interfacer is designed to manage all your input, tuning, muting, stereo summing, isolating, phase correction and output needs.
There are two versions of The Interfacer. The TX Interfacer (gold print) and The Interfacer (white print). Both versions have the same features and are made with the same components except that The TX Interfacer adds an audio transformer to give the option of ground lift and phase correction (read more below).
Summing
The Interfacer has two types of summing: Stereo Sum and Split Sum. To access these two modes, use the internal DIP switch to select which mode is best for you.
- Stereo Sum – This is the default mode The Interfacer ships with. In this mode use stereo effects as normal. When summed, the left and right inputs are merged and the exact same signal is sent to the left and right outputs.
- Split sum – Still use stereo effects as normal. When summed, the right input is ignored and the left input is split to both left and right outputs.
Ground Lift & Phase Correction (The TX Interfacer only)
The Interfacer TX comes with ground lift and phase correction for players that want to run more than one amp.
- Ground Lift – There are times when two amps are being used that an audible hum/buzz can be heard coming out of your amps. When plugged into one amp only, the hum/buzz is not present. This is commonly referred to as a ground loop. This happens when there is more than one path to earth. To safely fix this common problem, a transformer is needed to isolate your second amp and create one path to ground. Push the red ground lift button to isolate your right amp from your left.
- Phase Correction – Another common issue when running two amps is phase cancellation. Some amps are in phase in relation to each other and other amps are not. When amps are out of phase with each other they are cancelling each other out. This is most noticeable in the lower frequencies. Normally this would mean you can’t use those amps together. With the black phase correction button you can now put two amps that were out of phase, back in phase and working together. To access this, turn on the transformer (red button) and flip the phase (black button).
Master Mute
Hit the foot switch on The Interfacer to mute your signal before it reaches your amps. No matter what craziness is happening on your board, the master mute has the final say on what does or doesn’t get sent to your amp.
Inputs
There are two inputs on The Interfacer; a moveable buffered input and a passive input.
- Passive Input – Best to use if you have effects on your board such as a vintage wah or fuzz that don’t quite sound the same with a buffer before them. After your last fuzz or wah pedal you can then plug into the buffered input of The Interfacer to make use of the buffer and dedicated tuner output. The passive input can also be used for off-board expression pedals and tap tempo. Permanently connect either a TS or TRS cable from the passive send to a pedal that can receive expression or tap control and then patch an expression or tap pedal into the passive input.
- Moveable Buffered Input – The buffered input can be moved anywhere in your mono signal chain. Simply plug into the passive input, put all the pedals want you want before your buffer here. After the last pre-buffer pedal, plug into the buffered input to make use of the buffer and always on tuner output.
All Interfacers are made with high quality, durable components.
IMPORTANT – Use only 9vDC centre negative plug to power! 100mA
Dimensions including all jacks and switches are: 127mm long x 77mm wide x 73mm high.

Sleek, Functional, and Feels Like a Laptop Replacement
Color: Navy Blue
I’m really impressed with this keyboard case. The magnetic attachment is strong and secure, and the keyboard connects quickly without any issues. The trackpad is smooth and responsive, which makes using the iPad feel almost like a laptop. The backlit keys are a great touch, especially with the different color options, and the lighting is even and easy on the eyes.
The case itself feels well made and protective, and I like that it’s stain resistant because it stays looking clean. The navy blue color looks sleek and professional. It fits my iPad perfectly and doesn’t add unnecessary bulk. Battery life has also been solid so far.
Overall, this is a great value for the quality and features you get. Highly recommend if you want a reliable keyboard case that’s both functional and stylish.

Fairly Priced and Fairly Nice iPad Pro Case
Color: Light Pink
I was on the hunt for a case for my iPad Pro (6th generation), and let me tell you, it was a wild ride! I scoured every review I could find, but it was like trying to find a needle in a haystack. The ones that were reasonably priced had all sorts of issues, and the ones that looked fancy were way too expensive and had just as many problems.
Now, I know what you might be thinking: “You get what you pay for, right?” Well, I was determined to find a case that fit my budget and didn’t have too many complaints. After hours of searching, I finally stumbled upon a case that seemed to be a reasonable match.
Here’s why I picked this one: It has most of the features I wanted. It covers the lens on the back of the iPad, and there’s a holder on top for the pencil allowing it to charge. I’ve gone through two cases before, and they all started to wear out pretty quickly. I didn’t want to spend a fortune on another case that would just fall apart so I found this one to be reasonably priced. The case itself is nice and sturdy, and it’s a great fit for my iPad.
I charged the keyboard for the recommended 5 hours before I first used it, and I haven’t had a chance to test the battery life yet. But after charging, it was a breeze to connect it to my iPad.
A little heads up: the connect button is actually the “C” on the keyboard, not the command or control key. I know, I know, confusing! But once you press the keys, Bluetooth turns on, and connection to the iPad went without any issues.
I’ve seen some reviews mentioning that special characters weren’t working or that the keyboard would just stop working randomly. But so far, everything seems to be working perfectly. I’ll definitely update this review if anything changes.
One thing I really like about this keyboard case is that once it’s connected, you don’t have to reconnect it again. That’s a huge plus! Another cool feature is that the instructions for pairing and using the keyboard are right on the bottom of the keyboard, which is super handy.
Pros:
- style and fit.
- different angles for propping iPad while typing or watching videos
- instructions for pairing and use on the bottom of the keyboard,
Cons:
- The only downside I’ve found so far is that you can’t swivel the iPad from landscape to portrait because the case doesn’t allow for that movement. For me this is a minor inconvenience, because I just close the case and turn it to portrait. If that’s important to you, then this might not be the case for you. Another thing I have noticed is that sometime while I am typing, and I type fast, I will hit something and get dragged somewhere else on the screen. I think this is a user inspired issue, but it is not that big a deal for me.
Overall, this is a good functional case with a pretty good keyboard and iPad protection. I’m giving it 4 stars explained below.
My Stars Explained
5 - Like finding money in your old coat pocket - pure joy!
4 - Almost perfect - like a pizza with just one missing topping.
3 - Like a movie that’s just okay—neither a blockbuster nor a total flop
2 - Like a blind date that went horribly wrong - cringeworthy.
1 - Like stepping on a Lego in the dark - painful.

Perfect fit, secure pencil slot, great touchpad.
Color: Navy Blue
EXCELLENT Keyboard case. I tried several to find the right one. Tried a bluetooth keyboard by itself, but there wasn't the convenience of an "all in one". Tried another one that had a magnetic connection between the ipad and the keyboard, but the ipad was not as positionable as I needed it to be. This "folio-type" case is similar to what I use for all my other tablets and devices - slim, securely closing, perfectly fitting my 3rd gen ipad pro - AND the slot for the apple pencil is PERFECTION! The touchpad is a little stiffer than I like but then I realized I DON'T actually have to press it to use it - just a tap accomplishes the same thing. I rely on the touchpad for a lot and this case is just really exactly what I need.

good value and battery life
Color: Purple
Love this!! the keyboard has a good life on it and charges pretty fast. I at first didn't really like that it detaches, but being able to hold the keyboard in my lap and type on the screen while I sit on the sofa is actually pretty nice. the trackpad does have a bit of a learning curve, but gestures/hotkeys are all listed on the bottom so it's easy to check whenever necessary.
The material of the case itself also cleans really easy. I spilled a drink on it and it wiped right off. I feel like this is a pretty good value all things considered, especially when similar products at big box stores can eb a couple hudnred bucks.
The only downside is that the keyboard, while slim, does add a bit of bulk to the case. It's not a huge deal for me, but my boyfriend who also has an ipad did notice the difference immediately.
