Simon Jarrett is the founder and designer of Kingsley Amplification. He is a professional guitarist living in B.C. Canada, although he originally comes from the UK. He is a graduate from the renowned Guitar Institute in LA, where he studied with such legends as Scott Henderson. He is a versatile session musician covering many styles from rock, blues and country to latin and jazz.

Simon founded Kingsley Amplifiers in the year 2000, designing and building hand made tube guitar amplifiers and effects pedals.

From Kingsley –

“The Maiden is a tube preamplifier in a pedal format. It 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/power amp simulator or for use as a booster/second clean sound when plugged into the front end of another guitar amplifier.

There are two models available: the Maiden BF, inspired by the classic Fender blackface design and the Maiden D, based on the clean channel of a Dumble ODS type amplifier. These preamplifiers are primarily about clean tones but can also be set for edge of breakup sounds.”

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 250VDC for the tube plates.

The Maiden features controls for Volume, Master, Treble, Middle and Bass, as well as a 3-way bright switch (labelled Mode). In addition, pulling up the Midrange pot activates a mid boost.

Measurements: 3 7/8” wide x 4 ¾” deep x 2.56" tall

Power requirements: 9VDC @ 500mA, centre negative, 2.1mm jack

Weight: 1.27 lbs (575g)

This one is the Kingsley Maiden BF (Blackface) model. Besides its sister, the Maiden D (Dumble) pedal, Kingsley now also make a Top Boost version – the Maiden TB.

But it’s the BF model that we like. It is a super versatile and sweet sounding tube preamp that will bring your rig to life. It’s not just solid state amps that benefit from a Maiden in the loop, but any good tube amp with some clean headroom will just love what the BF brings to the mix.

The pedal can be used through the front of an amp and in this sense, operates as an additional gain stage much like an overdrive or boost pedal.

But the Maiden BF really shines when it is plugged directly into the “return” input of an amp’s effects loop. In this sense, it becomes the substitute preamp section direct into the amp’s power section. When it is used this way the Maiden pedal would be located at the end of the pedal chain and is the last pedal going into the amp’s effects loop return.

When used in this way with either a tube or solid state amp, it absolutely provides the warmth of a Fender Blackface era valve preamp in a most convincing manner.

This pedal presents as new. It is just over a year old and has never left the original owner’s house. You can order a new one from Kingsley, but the wait time used to be many months – and it’s probably more now in the COVID era. Which is why Maiden preamps that actually are for sale and available command a premium price.

Comes in its original Canadian post carton along with its 240v to 9v power supply.
