Fishman fulle circle 用户手册

Upright Bass Pickup

Description

Encased within a sturdy aluminum height adjuster wheel, the
Full Circle pickup offers accurate, transparent sound and
dependable performance. The pickup’s unique position within
the leg of a bass bridge achieves an amplified sound with fast
attack, lots of body resonance and good resistance to
feedback. Unlike many other bass pickups that add their own
signature sound, the Full Circle has little coloration. Plug in the
Full Circle and you’ll hear the sound of the bass, not the
pickup. The Full Circle  is a quick retro-fit on many instruments
with height adjustment wheels.

It is our wish that you are completely satisfied with this
product. If you have any comments or questions, we would
like to hear from you. You may reach Our Customer Service
department at tech@fishman.com or call 978-988-9665.

Retro-fit the Full Circle

to a bridge with installed wheels

Although it is preferable to have a repair-person install the pickup, it is also
possible for the player to retro-fit the Full Circle to a bridge with installed
wheels. Attempt only if you have experience setting up your own bridge and
sound post. The pickup replaces the wheel on the E string side of the bridge.
A matching wheel (without the pickup) is also included for the G string side.
Before you install the pickup, confirm that the threads in the bridge (1/4-20
or 6mm) will match those on the Full Circle.  

Fishman Transducers will not be responsible for damages to the pickup or
the instrument due to improperly installed wheels! 

The pickup is ‘hot’ on the flat face of the wheel; on the side with the non-
threaded post. For good performance it is crucial that the hot side of the
pickup lays absolutely flat with no gaps or voids where it contacts the bridge.
If necessary, sand the wood flat where it contacts the wheel before you install
bridge on the bass. (illustration A)

When you install the pickup, remove the RCA plug from the backside of the
output jack.  Replace the plug after the pickup is in place.

Setup

Once the wheels are mounted and the bass is tuned up, thread the white wire
through one of the wing holes in the bridge and hold it in place with one of
the neoprene plugs from the kit. (Illustration B)

Fasten the output jack behind the bridge and between two adjacent pairs of
strings. Then fasten the RCA  plug into the back of the output jack. 

Mind the Gap! 

For good pickup performance, leave a slight gap between the threaded side
of the wheel and the wood. If you close the gap, the amplified sound will
become choked and muted. (Illustration B)

Height Adjustment

Remove the RCA plug from the back of the output jack so the white wire does
not wrap around the leg as you turn the wheel. Turn both wheels equal
amounts for good contact with the pickup. To prolong the life of the pickup,
do not pinch the white wire where it joins the wheel. 

Plugging In

The Full Circle performs well plugged directly into most bass amps. But note
that for the most accurate sound, the Full Circle works best into an  “ultra
high impedance” (1-10 Mega-Ohm) preamp input. These days many bass
amps, active D.I.s and even some newer mixers have very high impedance
inputs, but many don’t. 

If your amplified sound is not as full and deep as you’d expect, you may have
an “impedance mismatch”.  We suggest you bolster the pickup with an
impedance matching preamp, such as a Fishman Pro-EQ Platinum Bass, Pro-
EQ II or B II. An Impedance matching preamp will strengthen the pickup,
expand its low frequency response and guarantee consistent sound with
whatever gear you plug into downstream. 

Tonal Adjustments 

(Illustration C)

Turn the wheel so the wire is perpendicular to the leg and the pickup will have
an open, resonant response. 

Turn the wheel 45 degrees so the wire faces one of the corners and the tone
will be somewhat drier and more focused, with less output. 

Please take the time to experiment and find the wheel position that best suits
your instrument and playing style.
