Acoustic Pickups

Can I install a BP-100 without clips?
If you have lost a Felted U-Clip that comes with your BP-100, there is an alternate method of attaching the pickup to your bass bridge. Since the U-Clips can be a tough item to locate at your local Fishman dealer, you can use a standard hot-melt glue gun and glue stick as a temporary or even permanent solution. Make sure you have a nice flat surface area on the bridge to affix the pickup. A sanding block is the best tool for this. Once the area is sanded flat, apply a liberal amount of hot-melt glue to the back side of each element and affix to the bridge. Remove any excess glue and use a clothespin (or the remaining U-Clip) to hold it in place until it dries. Once dry, you’re all set. To remove the pickup, just heat it up slightly with your average blow dryer and it will come right off.
Can the Matrix pickup element be cut to fit any length slot?
The Acoustic Matrix undersaddle pickup element comes in a standard length of 2.650″ (67.3 mm), with a sensing area of 2.500″ (66.55 mm), which will fit into 99% of the acoustic guitar saddle slots and string spacings that exist today. For custom length slots, we are happy to manufacture pickups on a special order basis (additional charges apply). Due to the nature of the manufacturing process, the Acoustic Matrix pickup cannot be cut to fit once it is made. Saddle slots over 3 inches can be accommodated with a 2-piece saddle, as we cannot manufacture a 1-piece pickup over 3 inches in length. Please see your local Fishman dealer for pricing and ordering information.
How do I combine an onboard preamp with a soundhole pickup?
A magnetic sound hole pickup can be added to many Fishman onboard preamp systems. The sound hole pickup’s signal wire will be wired to the “Ring” terminal of the output jack and the ground will be connected to the sleeve. If the soundhole pickup is active, like our Rare Earth pickups, you would remove the batteries from the sound hole pickup and install a jumper between the positive and negative battery terminals on the pickup. The battery wire of the pickup would then be connected to the “Switch” lug of the jack, so the onboard preamp and active sound hole pickup will run off the same 9 volt battery.
Narrow, Wide or Split format Matrix pickup - which do I need?
This designation refers to the width of the saddle slot. Some companies, like Martin, have traditionally used a 3/32” saddle slot, which we call “narrow”. Others, like Gibson, use a 1/8” slot, which we call “wide”. Split format is for less common instruments made by some companies, such as Lowden, which feature two saddles: a short one for the E and B strings, and a longer one for the remaining four strings. If you are unsure which model you need, measure your saddle carefully using calipers, or simply show your guitar to your installer. They will usually be able to see right away which size will fit your instrument. If there is any doubt, a “narrow” pickup can fit in a “wide” pickup slot and work reasonably well, but the reverse is not true.
How can I use the Powerchip with an Archtop Guitar?
We have periodically been asked to suggest a way to blend the Fishman Archtop Piezo replacement bridge signal with an existing magnetic pickup on an Archtop guitar. We have found the Powerchip to be an excellent solution to this problem. The Powerchip was initially designed to allow onboard blending of magnetic pickups with our Powerbridge Electric Guitar Piezo Bridge. It will also work on the Archtop and other similar blend situations. Two things to remember are: the Powerchip volume pot acts only as volume control for the piezo bridge. It is not a blend pot (See support topic ‘Powerchip Blend Powerbridge & Magnetic). Secondly, you must have access to a 9-volt battery which is needed to power the Powerchip. Once installed, you’ll have the option of a mono mixed signal or a stereo T-R-S signal from the instrument. The Powerchip is a diverse product that can open up audio possibilities in many instruments.

Amplifiers

Can Fishman acoustic amplifiers be used with electric guitar/bass?
Fishman acoustic amplifiers are designed for accuracy and transparency of acoustic instruments, including acoustic guitar, acoustic bass, mandolin, violin, cello, banjo, and more. Fishman amplifiers can also be used with solid body instruments like electric guitar and bass. For these instruments, acoustic voicing can deliver increased high frequencies when compared to a traditional electric guitar amplifier but the tone is more open and life-like. Fishman doesn’t recommend using distortions or overdrives with our acoustic amplifiers. The speakers are designed for fidelity and are not built to tolerate the square waves that distortions and overdrives produce.
Why are some Fishman amps rated at 24 volt phantom instead of 48 volt?
The Loudbox Artist and Loudbox Performer use a 24v high current phantom power supply standard that allows users to operate condenser microphones and other devices requiring phantom power without issue.  In many cases, the high current standard provides increased power and stability than 48v sources.

Combining the Acoustic Matrix and Rare Earth pickups
Did you know that you can combine the Acoustic Matrix active undersaddle pickup with the Rare Earth series of active magnetic soundhole pickups to create a new dimension in sound? This combination allows you to power both active systems from a single 9-volt battery and results in a T-R-S (Tip-Ring-Sleeve) output. The Acoustic Matrix signal on the tip of a stereo jack, and the Rare Earth signal on the ring, will allow you to send both signals simultaneously to separate amps, or channels in a mixer, to create your own acoustic sound. This modification requires the new Switchjack Equipped version of either the Acoustic Matrix Natural 1 or Natural 2 and any Rare Earth model pickup. We would be happy to email the wiring schematics for this modification, or you can simply check it out in the Wiring Diagram section of our website.
Adjusting Phase settings on the Acoustic, Bass and Pocket Blenders
Many players have questions regarding the correct way to set the Phase buttons on the external Blenders. An easy way to achieve the correct Phase setting is to start with the mic signal only. Listen as you switch back and forth with the mic Phase button. One setting will give you a fuller, richer sounding signal with a little more bass response than the other position. This will be your in-phase switch position. You then simply set the pickup channel the same as the mic. If the button is in the Out position on the mic channel, it should be Out on the pickup channel. Playing in-phase will allow you to get a richer, more feedback-resistant natural sound from your instrument.
Adjusting the microphone level on the Prefix Stereo Blender
There are frequent questions about controlling the balance between the undersaddle pickup and the microphone level when using the Prefix Stereo Blender. Balanced output levels between the microphone and pickup will allow greater control over your sound. We have provided a trim control potentiometer on the underside of the preamp to better enable you to balance these signals. To adjust the microphone signal, set the BLEND slider to the center position and, with a small screwdriver, adjust the potentiometer until both the microphone and pickup levels are balanced.
