ONBOARD GUITAR BOOST-EQ PREAMP

WARM CLEAN BOOST WITH GENTLE TILT-EQ AND VARIABLE GAIN

ONBOARD GUITAR BOOST-EQ PREAMP

HEAR IT IN ACTION

PREV
NEXT

From buffer level up to +16dB of clean FET boost with gentle TILT-EQ tone correction and Push-Push True Bypass.

BECOS Micro Boost-EQ onboard guitar preamp takes magnetic pickups signal and delivers a controlable low noise signal boost that pushes guitar amplifier into solo mode on-the-fly. A one-knob finely tuned TILT-EQ may be used to either boost High frequencies while cutting Lows, or viceversa, for better amplifier response when pushed by a boosted signal.

FET AUDIO CIRCUIT

FET preamp circuit design derived from original vacuum tube audio, calibrated for the best sounding clean boost.

TILT-EQ SIGNAL CORRECTION

Tilt-EQ with pivot center frequency around 1KHz allows gentle tone correction of boosted signal. Increase Highs while cutting Lows and viceversa. Leaves signal unchanged in the middle.

VARIABLE GAIN SETUP

Set and use only the right amount of gain needed for your boost needs. On lowest setting can be used as a FET buffer. The reversible knob can be used from either the front or back of the guitar.

PUSH-PUSH SWITCH POT

Replacement potentiometer in your guitar will be wired as Volume or Tone control. Route signal on-the-fly through the booster, with a quick and easy push. Push again to route signal True By-pass to the output.

PIN HEADER CONNECTOR

Allows fast and easy installation, with less soldering and clean wiring. All of the wires are already prepared and ready to connect.

AUDIOPHILE GRADE COMPONENTS

High quality polyester capacitors used in audio circuit assure the best possible sound & dynamics.

FLIP/SLIDE GAIN KNOB

Reverse gain knob to operate it from guitar front. Slide it to adjust height.

FAST INSTALL

Comes pre-wired with all accessories included, for a fast and easy installation.

WELL DOCUMENTED

Installation manual, written tutorials, wiring diagrams and video demos are provided.

BOOST-EQ ONBOARD GUITAR PREAMP

GUITAR SIGNAL BOOST ON DEMAND WITH GENTLE TILT-EQ

BECOS Micro Boost-EQ Onboard Preamp can be installed in any guitar to boost signal from passive magnetic guitar pickups. It is powered by one or two 9V batteries, connected in series; powering using 18VDC means bigger audio headroom (it is also the recommended voltage power for bass pickup boost).

Based on a FET implementation derived from original vacuum tube audio amplifier circuit designs, it was carefully calibrated for best sounding clean boost.

It features a variable gain control which starts from Unity Gain and goes up to +16dB of pickup's signal amplification. On lowest gain setting it can be used as very low noise FET Buffer.

A one-control TILT-EQ section allows gentle correction of boosted signal for better amplifier response, when pushed up front. Rotating this trimmer to one end it cuts LOWS while concomitantly boosting HIGHS and viceversa, when rotated to the other end. Pivot center frequency is around 1KHz. The amount of cut/boost sums up for a total of 12dB of signal correction. Left in the middle position, original signal is untouched.

Tilt-EQ must be used in conjunction to Gain level. Even at buffer level, you can apply a warm and gentle signal correction. The addition of a Tilt-EQ section allows for better frequency balancing of boosted signal. For instance, it is desirable to cut a little Lows from a boosted humbucker pickup while enhancing Highs. Likewise, a boosted single coil signal can be fatten up with some Lows while tampering a bit of highs. The result is a warmer musical response from guitar amplifier, which interacts differently with a boosted signal.

A PUSH-PUSH switch-pot is attached to circuit board, but potiometer side of it IS NOT part of booster's circuit. The switch part of it routes pickup signal through boost-EQ when in up position, and True Bypass when in down position.

Potentiometer side of the switch-pot only replaces the potentiometer in your instrument (volume or tone). It will be wired just the same.

CLEAN FLAT OR GENTLE CORRECTED GUITAR PICKUP SIGNAL BOOSTER

FET AMPLIFYING CIRCUIT INSPIRED FROM TUBE AMP DESIGN

BECOS Micro Boost-EQ is designed for transparent, clean, flat, guitar pickup boost, when TILT-EQ control is left in the middle position. Playing style or following gear setup change may require booster gain setting adjustments. Everything may be influenced by previous component in signal chain. Picking dynamics, gain level set on the booster, amp response on each channel, may all have an influence on the final sound.

TILT-EQ control allows for better ballancing of boosted signal, depending on pickup's characteristics. For example, a flat boost on all frequency spectrum for a humbucker pickup may reveal troubling low frequencies, but with TILT-EQ some of these Lows can be damped while boosting a little Highs. On the contrary, a single coil pickup may scream too thin when flat boosted. Enhancing Lows and cutting Highs a little can make a single coil sound fatter.

HOW TO INSTALL

Two soldering points and rewiring the replacement volume or tone pot. That's all that it takes.

EASY TO INSTALL

WIRING DIAGRAMS AVAILABLE ON SUPPORT SECTION

The booster comes latest in the guitar signal path - basically replacing your output connector. Its electronic circuit is attached to a Push-Push switch-pot which routes signal through booster or TRUE BY-PASS. Potentiometer side of the switch-pot is NOT part of booster's circuit. It will replace volume or tone potentiometer in your instrument.

Beside rewiring the potentiometer, there are only two solder points to make, input and ground. Existing output connector in the guitar is replaced with a Neutrik stereo connector. The booster is powered as long as (mono) instrument cable jack is plugged in. Very little current is drawn from the battery, which will last for months.

FREQUENTLY ASKED QUESTIONS

Find out what people usually ask us about.

YES. Installing it in a Gibson original or a Gibson-like guitar is the easiest installation because there is plenty of room in the electronic compartment. The Push-Push switch pot's shaft precise dimensions (9.8mm) allow for the easiest installation in place of bridge pickup controls (tone or volume), because they are placed on the edge side of the guitar, where the top wood is thinner. We did install it in place of neck pickup tone control though, where the body wood is a bit thicker (around 8 mm), and we still did it. Of course, every guitar is a bit different and the wood may be thicker or thinner from one instrument to another. Sometimes Gibson use "long shaft" pots for their controls, but they are in fact EXTRA long and the length is not always needed nor used, but they use long shafts because it is easier to install. For our case, with a minimal skillful hand and only if it is necessary, a bit of wood trimming with a small cutter around the hole on the inside electronics compartment, can provide up to 2 mm more. This is enough for an installation of our Push-Push pot even in the thicker part of the wood. In fact, our pots are exactly the same as those used by Gibson and other manufacturers for providing such feature, and it is the only one available in the market. So, if they installed it you can do it as well. If you have to trim the wood a bit and/or if you have shielding which add to the wood thickness, you will have to stick a small piece of isolation tape to avoid potentiometer's lugs to touch the shielding. We have a video installation of the Micro Booster in an original Gibson Standard Traditional guitar on our You Tube channel which you can check it up.

YES. Telecaster electronics compartment is very narrow and the bottom between the potentiometer and pickup switch may have to be routed in some Telecaster bodies, so that the 9V battery can be fit inside. Some trimming might be needed as well just near the tone or volume control to make room for booster's circuit. If needed, the booster volume knob can be taken out through the metal plate of the controls, simply by drilling a 6 mm diameter hole in the plate, at around 11-14 mm from the center of the existing control hole. The installation difficulty is medium for a skilled person which can handle sharp tools. We did it from the first time, so you can do it as well. We have a video installation of the Micro Booster in an original Gibson Standard Traditional guitar on our You Tube channel which you can check it up.

YES. There is plenty of room underneath the pickguard for the battery and booster's circuit. If needed, the booster volume knob can be taken out, simply by drilling a 6 mm diameter hole in the plastic pickguard, at around 11-14 mm from the center of the existing control hole. Some wood trimming may be needed in some bodies if booster is to be installed on the bridge/center tone pot. Please watch a Fender installation video on our You Tube channel.
