Preamps and Amplifiers
for Double Bass

Most piezo pickups require a high input impedance. But most bass guitar amps have only a low impedance input – which may results in a scratchy, thin and brittle sound from the piezo. Therefore, outboard buffer preamps are recommended in order to get the best sound from your pickup.

Most amps we offer already have a higher “piezo-friendly” input impedance - an external preamp may be used, but isn't necessary for buffering/impedance matching.



Headway EDB2 2-channel acoustic preamp

The EDB (Sheer Acoustic Equalizer Direct Blend) is a mega multi-purpose and compact external pre-amplifier box of pro-audio quality. You can completely shape your sound with its five band interactive EQ, switchable input impedance and three way Range Switch which cut unwanted low end tones, below the useable frequency range of the instrument. This cuts body handling noise, unwanted resonances, feedback and bowing noise. Feedback and other resonance problems may be further tackled by a very effective, broad ranging tunable notch filter and a Phase Reverse control.

Inputs are via Mono Jack, Stereo Jack and XLR, via Two Channels, which enable you to blend in an extra pickup, or Microphone and you can plug into them via one or two standard mono jack leads, a jack lead plus an XLR, or a stereo jack lead.

The Input Impedance Switches on each channel, allow you to optimize the voicing for any of the major pickup types, while a huge amount of extra levels can be applied via the Gain controls and additionally by the Master Volume.

Phantom power is also available to Jack In and XLR Inputs, making the unit friendly for use with quality Condenser Mics and Instruments wired with no battery inside instrument, but with active pickups needing powering.

Outputs are via a balanced XLR D.I. out and a line out Jack. If an earth loop is heard causing hum, you may kill it by pressing the Earth Lift Switch. The two outputs also allow you to split the signal, such as between Acoustic Combo amp for stage monitoring and an out front mixing desk.

The EDB can be mounted on its rubber feet, carried with you on the belt clip, or mounted via a mic stand, with an optional bracket. Powering is via two 9v PP3 ( 6F22 ) Batteries, or via plug in DC Power supply.

The “Swiss Army Knife“ for acoustic instrument amplification.

EDB2-HEThe two-channel preamp EDB2 H.E is the current model that Headway launched in 2020 as the successor to the successful EDB2. Once again, the already wide range of functions has been expanded. Each channel now has its own 5-band tone control, and the EDB2 now offers a "High Harmonics Enhancer Switch" (CH.1, CH.2 or both).

Lehle Sunday Driver Preamp/Buffer

Lehle Sunday DriverThe Lehle Sunday Driver is a high end preamp with a convenient compact format. It features JFET-based circuitry and provides two modes of operation, with selection via a mode selector switch with gold-plated contacts:
"D" stands for Driver; in this mode, the signal is amplified, with absolutely no modification, at the input impedance of 1 MOhm, efficiently eliminating losses on the route through leads and effects; the signal remains strong and clear, retaining its full dynamics.
The second setting "S" - as in Sunday - multiplies input impedance by four to 4 MOhm, bringing out previously inaudible details and, as gain increases, imparting to the bass sound a characteristic and unmistakable warmth that has given this preamp its name - the result is a sound "as mellow as a sunny Sunday afternoon" … Even at a 15dB gain setting, the Lehle Sunday Driver always stays clean and absolutely free of background noise, thanks to its studio-standard signal-to-noise ratio of over -100 dB.
With its broad output range of 20 to 100,000 Hz, the Lehle Sunday Driver, powered by a standard 9V (PP3) battery, can be used anywhere, whether as a buffer for piezo pickups, as a cable driver for stadium and other large stages, in complex effects set-ups or as a recording preamp - and not just Sundays!

Lehle Mono Volume

Lehle-Mono-Volume-10The Lehle Mono Volume is a volume pedal equipped with a precise magnetic sensor enabling it to operate almost wear-free. This sensor uses the Hall effect, named after Edwin Hall, to measure the strength of magnetic fields. In the Lehle Mono Volume the Hall sensor, which is made in Germany, is accurately calibrated to the built-in magnet and the control range of the pedal. The pedal moves only the magnet, the distance is measured by the Hall sensor which controls a VCA. Over the entire control range the Lehle Mono Volume transmits the full sound spectrum of the connected instrument. The input and output impedance always stays the same, ensuring that there will be no damping of higher frequencies as with potentiometers. The volume control of the Lehle Mono Volume ranges from -92 dB to 0 dB - so from a virtually muted level to the same volume. With a potentiometer a gain up to +10 dB boost can be additionally adjusted. The Lehle Mono Volume runs mechanically extremely smooth and steady, as it is equipped with low-friction bearings of a high-performance polymer, and there is no mechanical transmission of the pedal to other components. By means of an adjusting screw the mobility of the pedal can be modified very precisely.
The input impedance is 2MegOhms, so there is no need for additional external preamps/buffers when used with a piezo pickup.

  • active volume pedal
  • almost wear-free, no potentiometer
  • volume from -92 dB (muted) to 0 dB (Unity Gain) or +10 dB (Boost)

Acoustic Image

It's almost twenty years ago, when bassist an engineer Rick Jones launched the first series of the Acoustic Image Contra amp. This innovative and unconventional design had a cylindrical housing and a downfiring speaker, and was developped with the double bass player in mind. It soon became a huge success among double bass player around the world.
Rick Jones has continuously developed his amps and speaker cabinets further. The original downfiring speaker has now been replaced by speakers arranged upwards (Upshot) or sideways (Doubleshot, Coda), which provide an omnidirectional dispersion of the bass frequencies.
Acoustic Image Amps are available with one or two channels. Clarus amp heads are compact and lightweight, and even fit in the bass bag's accessory compartment.

AI Clarus SL S4plus (606IA Plus)

AI_clarus_sl The SL series amps are incredible small and light: about 900 gr and less than 20 cm length/depth. But nevertheless, this amp is very powerful (650Watt RMS @4 Ohm).

Also available with 2 channels and phantom power option – klick for comparison chart

Hevos Amps and Cabinets

Hevos is a small company from the Netherlands, specialized in making amps and cabinets for electric bass and double bass.

Midget 10/400C combo amp

midgetcombo10 The Midget 10″ combo is powered by the 400C combo amplifier. The combo amp has a continuous output of 400 Watts. The amp has 2 separated inputs. Additionally, the pre amp has a mute out to tune the bass inaudible, a phase switch for double bass, a -6 dB switch and a 4 band active tone control with a range of +/- 12 dB. The 400C is provided with all kinds of protection devices, such as a switch-on delay, clip indication, protection against short circuit of the loudspeaker output. At the backside of the amp there is an output for a headphone, a mute out and a symmetrical line out with pre/post switch. An extra Speakon loudspeaker output completes the 400C.
The power amp of the 400C is a class-D type with UcD technics and has a switched power supply. The amplifier delivers its maximum power of 400 Watts at 4 Ohms, so connecting an extra loudspeaker cabinet is possible. The Midget combo can ideally be combined with an extra Midget cabinet without tweeter.

  • Inputs: Active, Passive
  • 400 W
  • 10" speaker (24,50 cm) + slot tweeter
  • input impedance 5 MOhms - no preamp required for use with piezo pickups

400S amp head

The 400S is an ultra compact amplifier of 7x23x20 cm, with a total weight of 2 kgs. The 400S is suitable for both bass guitar and double bass. Thanks to the application of the newest technics the 400S is completely quiet, even at full power. The class-D technics takes care of the absence of heat dissipation, resulting in a very compact design. The 400S is an amplifier with a continues power of 400 Watts. The 2 inputs have separate Gain controls. This allows you to connect 2 basses at the same time, or in case of a double bass, 2 pick ups. Both inputs have a separate gain control. The led above input 1 is a clip indicator which turns from green into red as soon as the input signal is too high.
Input 1 has a –6dB switch to reduce sensibility if necessary. This could be the case by using an active bass guitar or double bass with separate pre-amp. The use of a separate pre amp for double bass piezo pick ups is not necessairy with the 400S though. Input 1 is also provided with a phase turn switch, which can be useful connecting a double bass with two different pick ups. By means of the switch one puts one pick up out of phase, resulting in a different sound.
The pre amp is also equipped with a mute out to tune the instrument soundlessly. The internal signal is then interrupted and will be available at the mute out to be sent to for instance a tuning gear. The tone control unit is a 4-band type and is very easy to use. The frequencies are 80, 250, 800 and 2500 Hz , +/- 12 dB. The amplifier has been built in such a way that in normal acoustic circumstances there will be no need to use the tone control.

Zadow amps

ze200_400The ze200 is designed and handmade by German engineer Michael Zadow. His philosophy is: the more knobs you have, the more you try to adjust during a performance … You always think it's not quite perfectly adjusted. Due to its clear frequency response, the ze200 EQ controls can stay in the neutral position in most cases. Nevertheless, the ze200 has a highly effective parametric mid EQ. The ze200 features a downfiring system: the bass speaker is directed downwards. This results in an omni directional deflection of the low basses. As a consequence the bassplayer can be clearly heard by the other musicians, the audience and of course himself. Middle and higher frequencies are directed forewards via a secondary speaker. The rounded housing with minimal wall thickness, offers superlative acoustic properties whilst being both light and robust. For both optical and practical reasons, the whole of the electronics is locatedin the housing. The ClassAB-Power Amp is designed to cope with 300Watts rms. An electronical limiting circuit cuts in at 200W to protect the valuable speakers from possible damage through overloading. The inherent power reserve of the power amp together with the down-firing system provide the ze200combo’s transparent sound and deep, rich bass.
Phantom power is available as an option (50,–€). This 9V powered input suitable for pickups like e. g. Schertler StatB, Vektor Kontramike and Bassbalsereit Aktiv.

  • "Downfiring" bass speaker (10"/25,4 cm) + mid range/tweeter (5"/12,7 cm)
  • input impedance 10 MOhm - no external preamp (buffer) needed for piezo pickups
