Tubesteader Gainlord

The Tubesteader Gainlord is a high-voltage, 12AX7 tube preamp built into a compact die-cast aluminum pedal enclosure, voiced after classic British stacks of the Plexi and JCM800 kind¹². It is a dual-channel design: one lower-gain channel and one higher-gain channel, each with its own control set, giving what Delicious Audio calls "two distinct voices for the price of one"¹. Premier Guitar describes it as built on real high-voltage tube circuitry, all in a compact pedal format³.

What it is and what it does

The Gainlord sits in the preamp pedal family rather than being a simple overdrive pedal. Its two channels are voiced after two eras of the same British amplifier lineage: a Blue Plexi channel and a Red JCM800 channel²⁴. Each channel carries its own Volume, Treble, Mid, Bass, Gain and Bright switch².

Delicious Audio describes the two voices in playing terms. The low-gain channel:

while the high-gain channel is:

Flip to the high-gain channel and the character changes: Tubesteader describes it as tighter and more aggressive, with cutting bite that still cleans up when you roll back your guitar's volume¹. A Bright switch on each channel adds presence where it counts¹.

Guitar Pedal X's reviewer Stefan Karlsson heard the same split, characterizing the Plexi channel as "beautifully punchy, and chunky / beefy, with quite a bit of bass in the core signal," and the JCM800 channel as "more focused and searing, exactly as you would expect"².

Controls

The Bright switch is worth a second look for gain-staging: Premier Guitar notes that on the high-gain channel it can act as a subtle gain boost, and Delicious Audio adds that the high-gain channel "even works as a subtle boost" in its own right¹³.

Power and connections

The Gainlord runs on 12V DC at 500mA, through a 2.1mm center-negative barrel connector¹². Its rear panel carries a TS In, a TS Out, and a Mini Remote Switch Port for the remote footswitch².

The remote switch port is what makes the two channels practical on a live board: rather than bending down to a toggle, you change channels from a remote footswitch. Guitar Pedal X reviewed the Gainlord together with Tubesteader's FS-2L remote switch, and a later writeup notes the FS-2L delivered a third channel on the Gainlord 2²⁴.

History and design

The Gainlord was designed by Tubesteader's Olly Balan, and it continues a line of tube preamp pedals from the Canadian builder. Guitar Pedal X places it as the successor to the Vox AC30-style Tubesteader ROY, calling the Gainlord "the even more instantly satisfying Plexi and JCM800" follow-up². Earlier entries in the builder's range include the Orange-voiced Sunkeeper preamp, the Beekeeper and the D-style LIGHTKEEPER V2.

Tubesteader built the Gainlord around classic British stacks, the amps the maker says defined decades of hard rock, with two distinct voices in one pedal: a Blue Plexi channel and a Red JCM800 channel¹⁴. Guitar Pedal X noted the circuit's lineage, observing that after Tubesteader's Vox AC30 style Roy, the Plexi and JCM800 voicings felt like a natural follow-up, and the pedal went on to take Gold as the site's number one overdrive of the year². In that year-end verdict, the reviewer wrote that the Gainlord delivered the most satisfaction of the bronze contenders, in a very close run against the Fuzz Fields overall⁴.

What reviewers said

Guitar Pedal X's year-end verdict was unambiguous:

In the site's overall "best of the best" roundup across all pedal types, the Gainlord placed among the bronze contenders, with Stefan Karlsson writing⁴:

That roundup lists the Gainlord 2 at $349, with Plexi and JCM800 channels, its FS-2L Remote Switch delivering a third channel⁴.

Guitar Pedal X's review also documented preferred settings for both channels, with the Blue Plexi channel set around Volume, Treble and Gain at 3 o'clock, Mid at 2 o'clock, Bass at noon and Bright off, and the Red JCM800 channel run slightly hotter on Mid and Gain². The same review recorded the practical details a board builder cares about: a die-cast aluminum enclosure measuring 4.7" x 5.7" (120mm x 145mm) with a height of 2.75" (70mm) including the tube protectors, and a weight of 1.6 lb (800 g)².
