01-Gold-RS.jpg Gold-plated Relays & Switches
The signal from the pickups of an electric guitar or bass is so weak that poor-quality cables, cold joints and cheap contact materials ruin your sound. Switch contacts need to be made of special materials to permit loss-free switching of these low-level signals. All Lehle switchers feature special relays and slide switches with gold-plated contacts for totally reliable, absolutely zero-loss switching.
02-3-band-EQ.jpg 3-band EQ
An EQ is primarily intended to raise particularly desirable frequencies in a sound spectrum as well as filtering out the undesired ones. With the 3-band EQ this can be accomplished very intuitively.
With pot T you control the highs, M is responsable for the mids and with pot B the basses. The treble control is a shelving filter, while the mids and the bass frequencies are boosted or cut via bell filters. The frequencies of the EQ are perfect for upright and electric basses.
05-Gain.jpg Adjustable Gain
Adjustment of volume or distortion using a gain controller is a vital feature in many situations. The gain controllers on the corresponding Lehle products feature black anodized aluminium knobs set back into the housing so that they can be easily fingertip rotated but keep their settings during performances and transportation.
07-18V.jpg Voltage Internally Doubled to 18V
To exploit the dynamics of tube amplifiers to the full, the input voltage of Lehle products bearing this symbol is rectified from the power supply socket, then filtered, stabilized and doubled to 18V.
When we designed the Basswitch Classic Boost we had in mind classic passive P, JJ and PJ basses. This compact preamp combines the Basswitch IQ DI´s boost with a 3-band-eq especially voiced for vintage basses. Additionally the treble control combines a passive high frequencies reduction with an active high frequency boost.
This can substitute the installation of active electronics in the instrument, collectors or owners of vintage instruments will appreciate this, and your vintage bass will receive a new sonic shine without altering the characteristic sound of your instrument.
The Basswitch Classic Boost allows gain adjustment of +/- 15 dB and can be used as a stand-alone booster, it can be teamed up with the Basswitch IQ DI for more options or work as a compact standalone preamp in front of an active monitor or bass cab.
The approved Lehle True Sound Technology ensures a great tone: starting from the discrete JFET input stage, up to the switching via gold-plated relais this booster offers a more than studio-standard dynamic range of over 110 dB with very little noise. The Basswitch Classic Boost works internally with 18 V, but is content with all power supplies between 9 – 15 V AC or DC. The extremely robust construction with its protected controls and indestructable switching mechanism will provide many years of joy with classical boosting!
 
 
Q: What is the effect of an impedance converter?
A: The sound will be freshened up and signal loss through long cable runs will be compensated.

Q: How can I compensate the signal loss on my effects board?
A: By using an impedance converter, which provides a high impedance input socket for the instrument signal and a low impedance output signal that is more resistent against loss.

Q: What is Lehle True Sound Technology?
A: Lehle True Sound Technology is based on individual measures that follow one common goal: transporting the sound and character of the instrument in the best way possible, without any negative alteration. It achieves an open and dynamic sound without losing any detail. The buffers are designed to easily transmit within the megaherz-range. The Lehle True Sound technology uses either goldplated relais or goldplated switches, even the smallest currents will be transported without any degradation for many years to come.
