V3 is a major up-grade to the V2 with many more features.
The V2 was basically a slightly simplified version of a Maiden D and a Page DS in one box. The new Juggler V3 is based on the same Dumble ODS inspired circuit with two 12ax7s, however it has all of the features of the Maiden V2 and Page DS, as well as some other useful features.

Juggler V3

The Bard’s bias modulating tube circuit provides classic, warm sine wave tremolo tones. The single Tungsol 12ax7 runs at high voltage for a full, rich and dynamic tube sound. The 9VDC power supply (provided) is converted to both 6.3VDC for the tube heaters and 275VDC for the tube plates.

The Kingsley Constable is a tube guitar preamplifier modeled after the classic "plexi" design of the late 1960's. It is designed to push a power amplifier directly but may also be used into the effects return of a guitar amplifier effects loop. While the most authentic plexi tones are achieved by using one of the above methods, the Constable also features a mode of operation that attenuates its output to allow it to be run into the front end of a guitar amplifier or in front of other guitar effects pedals, for a clean boost or mild to medium drive pedal.

The Kingsley Constable uses two 12ax7 tubes running at high voltage (around 270VDC) to get the most authentic valve tone out of its hand wired circuit.

Constable V2

The Harlot V3 is a hand-wired tube overdrive pedal using a single 12ax7 tube running at high voltage and a JFET transistor that is used to push the 12ax7 into overdrive. It covers mild, smooth tones through mid gain crunch to fairly aggressive rock tones. A second footswitch takes the Harlot into a higher gain mode which is great for increasing saturation and aggression for solo tones. The Harlot sounds natural, fat, dynamic and is very touch sensitive.

Harlot V3

The Squire preamp pedal is suitable for running directly into a power amplifier, running into the effects return of an amplifier’s effects loop, recording direct when combined with a cabinet simulator or for use as a booster/second clean sound when plugged into the front end of another guitar amplifier.

There are three models to choose from: the original Squire, inspired by the Dumble clean channel; the Squire BF, similar to a black face fender circuit and the Squire TB, modeled after the Vox top boost circuit.
