The Kldguitar FREQ Booster is a discrete FET preamp pedal with a low impedance output. It is based around the classic Xotic EP booster and produces a shimmering boost tone that adds some high end sparkle and definition.
It features up to 20db of gain on tap with two switches to customize the boost. One is a Bass Boost and the other is a Bright switch. The default setting is Bright on/Bass Boost off. This provides extra sparkle for the darker sounding instruments and is great for that extra edge or shimmer.
The Bass Boost adds just the right amount of low end for single coils to keep up. By turning off the Bright Switch you can get a full frequency boost that is transparent and gives you back what you put in.
It’s review time again and this little pedal from KLD http://www.kldguitar.com is featured today.
This pedal is based off the preamp section of an Echoplex EP-3 there is one volume control that provides up to 20db of clean boost into your signal.
Toggles switches are included on top of the pedal for bass and bright settings. This is a welcome addition as the Xotic EP Booster has these controls located inside the pedal which makes accessibility a hassle, not so with the KLD Booster! Thumbs up here.

These are 100% hand-made in China and the quality of build is excellent throughout with a nice heavy and thick steel enclosure.
The footswitch is heavy-duty and is easy to stomp on and off. The sloped face design is good on pedal board as it makes accessing the pedal with your foot easy. A fairly bright red On/Off LED is included although it isn’t super bright it is perfectly visible when the pedal is engaged. This pedal also features true bypass. Battery access is via a thumb screw on the bottom of the pedal and makes battery changes easy. Also with a current draw of only 5ma you can run this on a 9v battery for many hours.
This is where things get interesting. This pedal provides an enhancement to your guitar tone. With the volume control setup far left (off) there is still a slight boost to your guitar signal when engaged. The tone seems to get uplifted with a fuller sound and more sparkle on the top end. You can tailor the sound by toggling the bright and bass controls giving you a flatter bass response or treble or boosted response for both.
With a valve amp on clean it adds a 3 dimensional sound to you guitar which is excellent. When overdriving the amp with a pedal or the amps onboard overdrive the pedal pushes the signal harder and causes a lovely extra layer of gain without any added compression.
As a lead boost it works very well with the amount of boost on tap. Even with the volume control at noon the tone is boosted significantly. You can get some really creamy lead tones with this pedal pushing your amp. I especially liked this pedal with the following chain. KLD Booster into a compressor and then into an overdrive pedal to amp. this was blues heaven with a fat, round and bold overdrive tone!
If you are looking for a FET based booster for your rig you could do far worse than the KLD Booster! This isn’t just a boost in the tradition sense, this is a tone enhancing pedal and boost. Add some preamp sparkle and low end to your guitar especially when stacking pedals.
Price wise these run about $80 which is far cheaper than the competition.
A great all round pedal no complaints at all with build, features, tone or price.
