The DREAMCOAT has the exact specs of the Aiwa TP-1011 reel-to-reel preamp that some classic rock legends used; with some extra features. It can be an unruly, velcro-y, and sputtery beast, but one that can be tamed at low levels for a more classic rock approach. Think of it like a console being blown out but completely under your control. The SKEWER operates similarly to our Naga Viper pedal, but rather than being based on the Dallas Rangemaster, it is based on the Hornby-Skewes Treble Booster—another iconic piece of the classic rock puzzle. All the pedal geekdom about what is in these pedals can be found below.
The DREAMCOAT and SKEWER will be sold exclusively as a box set for one month and at a discounted rate. After the first month, people can get each pedal à la carte but at full retail price. The pedals were designed to be used individually, but they really come to life when used together. The artwork of the two pedals flow into each other as one cohesive piece.
What began as an exploration of a specific '60s and '70s classic rock tone, evolved into a multidimensional gain machine capable of anything between unruly sputtery fuzz and classic rock chime. This is not meant to make you sound like a classic rock god, it is meant to inspire you from using some of the same tools they used that would otherwise be inaccessible in pedal form. The heart and soul of the Dreamcoat is a near-exact recreation of the preamp circuit from the Aiwa TP-1011 reel-to-reel deck that can be found in '60s and '70s classic rock recordings. All of the functionality of that unit is present, from sparkling cleans to powerful crunch and glassy leads, but the “Sat” control gives you an extra layer of grunt, allowing the Dreamcoat to range between near-dry tonal indifference to complete “melting-amp” Neil Young-esque tweed sounds. A certain classic rock sound wasn’t just a tape deck, though. Some players installed a passive inductor-based frequency “booster” into their guitars that cut both sides of the spectrum around the resonant frequency of their guitar, giving the appearance of frequency boost. To that end, we’ve added a frequency booster circuit that doesn’t cut anything, giving you a richer tone with a little oomph where it counts. To top it all off, we’ve included a clean blend circuit that begins after the frequency boost and ends after the tape preamp, so you can EQ the sum of your clean tone and dirt, all while preserving your pick attack and presence. The whole shebang runs at 20V, just a hair higher than the original Aiwa, expanding its capabilities and delivering tons of headroom.
FREQ: This controls the amount of boost at a specified frequency band, from 2.4KHz to 5KHz, which you set with the internal trimmer. When the knob is fully counter-clockwise, it’s out of the circuit. When you turn it up all the way, you’ll get a full 10dB boost at the selected frequency. Warning: a little goes a long way with this control, as ~4KHz is where pink noise and other unpleasantries live.
BLEND: This control blends the signal coming out of the Freq control with the Aiwa deck circuit. Nudge it south-of-max to gain back some of your pick attack, and turn it all the way down to hear just the EQ’d dry signal. When all the way down, make sure you turn your master up to compensate and vice-versa. When your Sat and Mic Vol are cranked and your Blend is just above 0, the resulting dynamic between your dry signal and those more extreme splatty Dreamcoat settings create a truly unique tone.
SAT: Controls the amount of feedback present in the first stage of the Aiwa unit. You can think of it as a “gain range” control. This control was not included on the original unit and was set to a fixed value. The default setting on the original is a hair past noon, everything else is extra. If you find that you are getting too much sputter, turn this control down.
MIC VOL: This is the original “distortion” control of the Aiwa deck and controls the total “distortion” of the circuit.
MASTER: You know what this does. You will never want for volume with the Dreamcoat, it can get punishingly loud. After all, the Aiwa was meant to drive speakers! As you adjust the Blend control, you may need to turn this up.
FREQUENCY TRIMMER: The famous user of the AIWA
TP-1011 tape deck had this passive “boost” tailored to the resonant frequency of their guitar, accentuating pinch harmonics. You may want to spend some time dialing this in. This is definitely a “set-it/forget-it” type of control, as you dial it to suit your guitar best. Of course, you can experiment with different frequencies and let the FREQ knob do the talking.
The DREAMCOAT is very sensitive to how hot your pickups are, what pickup you’re on, and how clean or dirty you set your amp. If your guitar has a super high output, then it’ll be easier to reach that sputtery, blown out sound and so you’ll need less of the SAT control. Your guitar’s volume knob can be a great way to quickly move between DREAMCOAT tones. Full guitar volume could be that blown out sound and low guitar volume can give you a pleasant boost.
The Dreamcoat requires a 9V power supply center-negative and draws 44mA. Any more current than that is A-OK, but you can’t exceed 9V without letting the smoke out. Bad things will happen, including but not limited to shouting expletives and more importantly, voiding your warranty. True bypass.

The TP-1011 was originally designed to accept a microphone input. Microphones operate at as low as -60dBu, and guitars 20dBu higher, so a guitar signal naturally overloaded the front end, creating its signature distortion. Unlike the original Aiwa unit that runs at 18V, the circuit didn’t really do the amp-melting thing until I increased the operating voltage to 20V, and so that’s where we stand. The 20V
operating voltage is supplied via a shunt-regulated charge pump, so plugging a standard 9V power supply into it does the trick.
When you adjust the Blend control, keep in mind that the “clean” sound is actually whatever you feed into the Dreamcoat, so running another pedal up front will allow you to blend the signals in parallel. This is a boon for you gain stackers out there, or you can get creative with it---try plugging in a ADT pedal or a subtle chorus up front and backing off the Blend control to let your cleans really jump out.
One of the most recognizable pieces of gear in the Classic Rock canon is the old Hornby-Skewes Treble Booster, a version of the classic effect used by too many artists to list. While almost all of them used a Rangemaster, the Hornby-Skewes version came stock with a silicon transistor for a more biting sound that cut through even the densest of mixes. The SKEWER stays true to that circuit, giving the old JHS unit the same treatment as our Naga Viper. This lets you dial in the desired frequency range from rich and full to treble-heavy, as well as control the amount of boost. You can also vary the amount of transistor gain for some extra juice. Some players had their original Treble Booster modded to play nicer with the rest of their gear. We’ve taken the liberty of giving you that mod as well, which is fully adjustable via the trimpot inside. Further enhancements include a noise reduction filter and anti-pop switch circuitry. This one bites just a little harder than our Naga Viper, and sounds fantastic with the DREAMCOAT.
SKEW: Adjusts the frequency response of the boost, which also slightly affects the gain. When dialed fully counter-clockwise, you get full range and max gain. When dialed fully clockwise, you get the stock setting of the original H-S Treble Booster.
BOOST: Adjusts the amount of boost. Stock H-S setting is about 2/3 up.
EXTRA: Adjusts level of gain extracted from the transistor. Crank this setting to get rowdy.
INTERNAL TRIMMER: This is a master volume control. It's included because rumor has it that certain players had their TB modded for master volume to make it sound better with their amps. Default is all the way up.
• The Skewer sounds great going into the DREAMCOAT but you should dial the Skewer’s internal trimmer back a bit before doing so.
• The Skewer operates similarly to our Naga Viper pedal, but rather than being based on the Dallas Rangemaster, it is based on the Hornby-Skewes Treble Booster.
The Skewer requires a 9V power supply center-negative and draws 1mA. Any more current than that is A-OK, but you can’t exceed 9V without letting the smoke out. Bad things will happen, including but not limited to shouting expletives and more importantly, voiding your warranty. Accepts 9V battery. True bypass
The Skewer has an incredibly low current draw (1mA), and so a battery will last for months and months. All battery operated effects will continue to drain the battery as long as a cable is plugged into the pedal’s input. However, the original Hornby-Skewes Treble Booster did not have a jack-based battery defeat, and as such, neither does the Skewer.
If you insist on running the Skewer with a battery, please remove it when it’s not on your board or in storage.
