One-Knob Boutique Gain

The MORE preamp pedal made by Union is a clean(ish) boost that does exactly what it says on the tin. With one dial, you can't go wrong in getting the kick up the backside your tone needs.

Union Pedals - Has the Captain Found His New Favourite Overdrive?


A simple volume boost is in effect all the way up to around 2 o'clock. It's particularly great for pushing overdrive or distortion volume or adding a bit of honest gain. Turn it up to 10 and you'll get a rich fuzziness without muddying tone. As with most Union pedals, everything remains classy. MORE is designed to enhance your tone rather than wreak havoc.  

Union Tube & Transistor

Union Tube & Transistor are a small company based in East Vancouver that make high-end, boutique pedals with rich tones. The MORE maintains the company's creative direction in making top quality, honest-sounding pedals.

Here's what Union Tube & Transistor say about the MORE:

This pedal is a guitar preamp capable of sweeping from +5db up to +40db of clean gain. Its maximum undistorted output level is +16dBu and it is intended for use with a tube amp.


The everMORE can offer some nice gain structuring when run in conjunction with other overdrive or distortion pedals but it also has enough gain to clip the converters in many digital pedals when maxed out so keep this in mind when placing it in your signal path. The unit is yours and you are obviously welcome to do with it as you please, our suggestion however is to put it just before your tube amp or if you are running a series of pedals to put it last in the signal chain.


There is a lot of gain on hand so we thought we would tell you a few of the scenarios in which we have found the pedal particularly useful.

Solo - From minimum to around 12 o'clock . In this range the unit will definitely let your guitar punch from a hint to wow!

Sweeten All - From 10 o'clock through 2 o'clock. Leave it on and forget it. This will help tickle your first pre-amp tube and you may find it becoming the missing link in your tone.

Low volume gain/Holy crap - From 2 o'clock through the Maximum there a couple nice features. First by taking a low gain amp and really overdriving the first tube you can attain nice gain structure and have your amp breaking up at 1 or 2 instead of the usual 6-7 (this is like the Sweeten but with more gain). Second if you have a dimed out amp and feel like you can't get any more out of it and want that holy crap factor, go from off to on in this setting and let it rip.
